Safety Section 1-2
SAFETY
Never operate the Sweeper until you have read and completely
understand this Manual, the Truck Operator’s Manual, the Auxiliary
Engine Operator’s manual, and each of the Safety Messages found in
these Manuals and those affixed to the Sweeper and its components.
Learn how to stop the Sweeper’s engines suddenly in an emergency.
Never allow inexperienced or untrained personnel to operate the Truck
and Sweeper without supervision. Make sure the operator has fully read
and understood the manuals prior to operation. (SWG-4)
Always maintain the safety decals in good readable condition. If the decals are missing,
damaged, or unreadable, obtain and install replacement decals immediately. Consult your
authorized sales representative for decal replacements. (SWS-1)
All Safety Shields, Guards and other Protective Safety devices should be used and
maintained in good working condition. All safety devices should be inspected carefully at
least daily for missing or broken components. NEVER REMOVE PROTECTIVE SHIELDS
AND GUARDS! NEVER MODIFY OR CUT PROTECTIVE SHIELDS OR GUARDS!
When shields or guards are removed to access areas for maintenance, they must be
replaced and be in good condition before operating. Missing, broken, or worn shields,
guards, and other protective devices must be replaced at once and prior to operation to
reduce the possibility of injury or death from thrown objects, entanglement, or contact. (SWS-2)
The Sweeper must be equipped with a fire extinguisher, rated for all fires, in an accessible
and visible area. The fire extinguisher should be inspected routinely by a certified inspector
for operational use and replaced as needed. Never obstruct access to the fire extinguisher.
(SWS-6)
Repeated or substantial breathing of hazardous dusts, including
crystalline silica, could cause fatal or serious respiratory disease including
silicosis. Concrete, masonry, many types of rock, and various other
materials contain silica sand. California lists respirable crystalline silica as
a substance known to cause cancer. Operation of this equipment under
certain conditions may generate airborne dust particles that could contain
crystalline silica. In those conditions, personal protective equipment
including an appropriate respirator must be used. If excessive dust is
generated, a dust collection or suppression system should also be used
during operation. (SG-41)

SAFETY
In addition to the design and configuration of this Sweeper, including Safety Signs and Safety Equipment,
hazard control and accident prevention are dependent upon the awareness, concern, prudence, and proper
training of personnel involved in the operation, transport, maintenance, and storage of the machine. Refer
also to Safety Messages and operation instruction in each of the appropriate sections of the Truck and
Auxiliary Engine Manuals. Pay close attention to the Safety Signs affixed to the Sweeper. (SWG-5)
SAFETY
DRIVER SAFETY INSTRUCTIONS AND PRACTICES
SAFETY
The operator of the Sweeper must be trained in the operation and safe use of this machine.
The operator must read and completely understand the operator’s manuals of the Sweeper,
Truck and Auxiliary engine manufacturers. New operators should be trained in an open
area clear of obstructions before operating on public roadways. If operation of the entire
Sweeper unit (Truck, Auxiliary engine, and Sweeping Components) is not completely
understood, consult your authorized sales representative for a detailed explanation. Never
allow an untrained or unqualified driver to operate the Sweeper. (SWD-01)
The Sweeper driver must meet the requirements and possess a Motor Vehicle License as
determined by the state in which the Sweeper is operated if used on public roadways.
Contact your local State Department of Public Safety office for special licensing
requirements to operate the Sweeper in your area. (SWD-2)
NEVER use drugs or alcohol immediately before or while driving or
operating the Sweeper. Drugs and alcohol will affect an operator’s
alertness and coordination and therefore affect the operator’s ability to
operate the Sweeper safely. Before operating the Sweeper,
an operator on prescription or over-the-counter medication
must consult a medical professional regarding any side
effects of the medication that would hinder their ability to
operate the Sweeper safely. NEVER knowingly allow anyone
to operate this Sweeper when their alertness or coordination
is impaired. Serious injury or death to the operator or others
could result if the operator is under the influence of drugs or
alcohol. (SWD-3)
Always wear OSHA approved Personal Protective Equipment (PPE) while operating,
servicing, repairing, and/or cleaning the Sweeper. PPE is designed to provide bodily
protection during such activities.
Personal Protective Equipment includes:
• Protective Eye Wear
• Steel Toed Safety Footwear
• Gloves
• Hearing Protection
• Close Fitted Clothing
• Hard Hat-When working around a raised hopper.
• Respirator-Depending on conditions and material being swept or cleaned.
Specialized protective equipment may be required if dangerous or hazardous material is being swept by or
cleaned from the Sweeper. (SWD-4)

Safety Section 1-4
SAFETY
Prolonged operation of the Sweeper may cause operator boredom and/or fatigue affecting
the safe operation of the Sweeper. It is recommended that the operator take scheduled
work breaks to help prevent these potentially impaired operating conditions. If possible,
completely shut down the Sweeper, exit the cab and move around stretching your arms and
legs. Never operate the Sweeper in a fatigued or bored mental state that impairs proper
and safe Sweeper operation. (SWD-5)
Do not operate, or perform maintenance to, the Sweeper while wearing loose fitting
clothing. Entanglement of loose clothing with the rotating elements can result in serious
injury or death. Stay clear of all rotating elements at all times. (SWD-7)
OPERATION SAFETY INSTRUCTIONS AND PRACTICES
Use both hands for support when getting on and off the Sweeper. Use handholds and
steps on the Sweeper for support when boarding the Sweeper. Never use the Sweeper
control levers for support when boarding the sweeper. (SWO-1)
Use available Sweeper handholds and steps to exit the Sweeper. Make sure you have
solid footing before stepping down. Be careful of your step and use extra caution when
mud, ice, snow, or other matter has accumulated on the steps or handrails. Never rush to
exit or jump off the Sweeper. (SWO-2)
Do not attempt to mount the Sweeper or Truck while the machine is moving.
Never attempt to mount a runaway Sweeper. Serious injury or death may
occur from being run over by a moving Sweeper. (SWO-3)
BEFORE leaving the Truck’s seat, always engage the parking brake and/or set the Truck’s
transmission in parking gear, stop the engine, remove the key, and wait for all moving parts
to stop. Never dismount a Truck that is moving or while the Truck and Auxiliary engines
are running. Operate the Sweeper controls from the Truck seat only. (SWO-4)

Safety Section 1-5
SAFETY
PROLONGED EXPOSURE TO LOUD NOISE MAY CAUSE
PERMANENT HEARING LOSS! Sweeper operation can often be
noisy enough to cause permanent hearing loss. We recommend that
you always wear hearing protection if the noise in the Operator’s
position exceeds 80db. Noise over 85db over an extended period of
time will cause severe hearing loss. Noise over 90db adjacent to the
Operator over an extended period of time will cause permanent or total
hearing loss. Note: Hearing loss from loud noise [from sweepers,
chain saws, radios, and other such sources close to the ear] is
cumulative over a lifetime without hope of natural recovery. (SWD-6)
SAFETY
Always wear a seat belt while driving the Sweeper during operation and
transport. Serious injury or even death could result from falling out of the
Truck or from being involved in a collision. (SWO-5)
SAFETY
Start the Truck and Auxiliary engine only when seated and belted in the
Truck’s operator seat. Operate the Sweeper controls only while properly
seated with the seat belt secured around you. Inadvertent movement of the
Truck and/or Sweeper components may cause serious injury or death to the
operator and passersby. Read the Truck and Auxiliary Engine operator ’s
manuals for proper starting instructions. ( S W O - 6 )
Use the right side steering only for sweeping, and never while exceeding 15 MPH. For
travel, the Sweeper must be driven from the LEFT side ONLY. If the Sweeper is to be
operated from the right hand side, make sure the Sweeper’s mirrors are aligned for visibility
from the right hand side steering position. (SWO-37)
Sweep only in conditions where you have clear visibility of the area being swept in daylight
or with adequate artificial lighting. Never sweep in darkness of foggy conditions where you
cannot clearly see at least 50 feet in front and to the sides of the Sweeper. Make sure that
you can clearly see and identify passersby, steep slopes, ditches, drop-offs, overhead
obstructions, power lines, oversized debris and foreign objects. If you are unable to see
these types of items, discontinue sweeping until visibility improves. (SWO-8)

Safety Section 1-6
SAFETY
Transport the Sweeper only at safe speeds. Serious accidents and injuries can result from
driving this Sweeper at unsafe speeds. Become familiar with the driving characteristics of
the Truck and how it handles before operating or transporting on streets and highways.
Make sure the Truck’s steering, brakes, and wheels are in good condition and operate
properly.
Before transporting the Sweeper determine the safe transport speeds for you and the machine. Make sure
you abide by the following rules:
Test the Sweeper at a slow speed and increase the speed slowly. Apply the brakes smoothly to determine
the stopping characteristics of the Truck equipped with the Sweeper. As you increase the speed of the
Truck, the stopping distance increases. Determine the maximum safe transport speed for you and the
Sweeper. When driving down a hill or on wet or rain slick roads, the braking distance increases: use
extreme care and reduce your speed. Do not operate the Sweeper with weak or faulty brakes.
•
Obey all traffic laws and regulations. Never exceed the posted speed limit.
•
The Sweeper has a high center of gravity that may be further increased when carrying a loaded hopper
and/or a full water tank. Use extreme caution when transporting at highway speeds. Slow down for sharp
corners to avoid tipping or turning the Sweeper over.
•
Only transport the Sweeper at the speeds determined as safe and which allow for proper control of the
machine while driving and stopping during an emergency.
•
When operating in traffic, use the Sweeper’s directional indicator or signal lights to indicate your
movement. Always use the Sweeper’s flashing signal lights and other equipped warning features to alert
motorist of your presence and slow moving speed when sweeping in traffic. Be Aware of Traffic Around
You and Watch Out for the Other Guy. (SWO-9)
When transporting the Sweeper between locations, follow all local traffic laws and
regulations. Disengage all Sweeper controls, raise all sweeping components, gutter
brooms, sweeper heads, make sure the hopper is completely lowered, and disengage all
warning signals prior to entering vehicle traffic. (SWO-10)
Before starting to sweep, the sweeping components must be engaged and operating at the
rated speed before moving forward. Sweeping debris before the Sweeper has reached its
rated operation speed may result in debris binding between the sweeping components.
(SWO-54)
Do not exceed the rated operating speed for the Truck and Auxiliary engines. Excessive
operating speeds can cause engine and Sweeper component failures resulting in possible
serious injury or death. (SWO-12)
Sweep at a speed that allows you to safely operate and control the Sweeper. Safe
sweeping speed depends on street condition and the type and amount of debris being
collected. Normal ground speed range is between 1 and 3 mph. Slow down for corners,
curbs, parked cars, protruding signs and other obstacles. Use slow traveling speeds
when operating on or near steep slopes, ditches, drop-offs, overhead obstructions, power
lines, or when debris and foreign objects are to be avoided. (SWO-13)

SAFETY
KEEP AWAY FROM ROTATING ELEMENTS including the Sweeper gutter brooms and
sweeping head to prevent entanglement and possible serious injury or death. Be aware
that rotating elements can pull bystanders into the Sweeper. (SWO-14)
SAFETY
Never reach outside the Truck cab to pick up a foreign item or to clear an obstacle such as
a tree limb or road sign impeding passage. Stop the Sweeper, shut down all sweeping
components, wait for all moving parts to come to a complete stop, and then exit the cab to
handle objects that are hindering Sweeper operation and passage. (SWO-15)
Do not operate the Sweeper if excessive vibration or noise exists.
Shut
down the Sweeping components and the Truck and Auxiliary engines.
Inspect the Sweeper to determine the source of the vibration or noise.
If
brooms are loose, damaged, or missing, replace them immediately.
Do not
operate the Sweeper until all necessary repairs have been performed and the
Sweeper operates smoothly. Operating the Sweeper with excessive vibration
can result in component failure and broken objects being thrown outward at
high velocities. To reduce the possibility of property damage, serious injury,
or even death, never operate the Sweeper with missing or damaged
components . (SWO-16)
Never attempt to sweep debris that is too large for the Sweeper to pick up (oversized
objects such as broken limbs and discarded tires). Such objects may plug the sweeping
components and cause serious mechanical damage to the Sweeper. If possible, carefully
place such objects out of the Sweeper and traffic path until properly removed by another
means. (SWO-17)
Objects such as wire, cable, rope, and chain can become entangled in the rotating parts of
the sweeping components causing mechanical damage. Entangled items caught in the
brooms can sling outward possibly injuring or entangling the operator or passersby. Any
objects that might become entangled in a sweeping component and those which could plug
the suction tubes should be removed from the area before beginning to sweep. (SWO-18)
KEEP AWAY FROM MOVING ELEMENTS including the spinning brooms and moving
conveyer to prevent being drawn into the Sweeper and possible serious injury or death.
Keep items that might be drawn into the Sweeper, such as tools and hoses clear from
moving components. (SWO-55)

Safety Section 1-8
SAFETY
Use extreme caution when dumping contents of the Sweeper. Be aware of
bystanders and animals in the area. Select a dump site on level ground and
clear of overhead obstructions that could be hit when raising the hopper.
Serious injury or death to the operator, bystanders and animals could occur if precautions are
not taken when dumping the contents of the hopper.
When positioning the truck at the dump station, choose an accessible location only on level ground.
Raising the hopper on unlevel ground increases the possibility of tipping.
•
Make sure the area is clear of ground and overhead obstructions.
•
Never raise the hopper bin unless you can clearly see all overhead structures. Make sure you stay clear of
all utility lines.
•
Do not dump the hopper over a pit area where the ground may cave in or is unstable.
•
Make sure the outriggers contact solid stable ground before raising the hopper.
•
Stay in the cab of the sweeper with the windows rolled up when dumping the hopper.
•
Use care when positioning the Sweeper to the dump station. Your vision, especially to the side and rear of
the Sweeper may be reduced by the size of the Sweeper. Use side and rear view mirrors to aid vision. If
you cannot see the dump site clearly, stop the Truck and examine the area. If necessary, request
assistance to guide you while backing the Truck into position.
•
If the hopper will be in the raised position for more time than is normally required to dump, or if someone
is going to get under the hopper for repair, maintenance, cleaning or any other reason, secure the safety
prop into position.
•
Never drive the Sweeper with the hopper in the raised position. Traveling with the hopper
in the raised position increases the chances of colliding with overhead obstructions. In
addition, the center of gravity of the Sweeper is higher with a raised hopper, making the
unit more prone to tipping over. (SWO-23)
Do not allow the Sweeper to come in contact with potentially dangerous and/or hazardous
material. Such hazards may include, but are not exclusively limited to, the following:
•Fire Hazards- Fuel spills, burning material,
•
Chemical Hazards- Chemical spills, discarded chemical containers, batteries,
•
Biological Hazards- Decaying Carcasses, Biomedical Waste,
•
Radioactive Hazards-Radioactive Waste, Radioactive Material,
•
Cutting Hazards-Broken Glass, Lumber with Protruding Nails,
•
Carcinogenic Materials-Asbestos,
•
Corrosive Materials-Batteries, Acids and Bases.
In most areas, these types of material require special handling requirements for safe collection and proper
disposal and should not be collected by the Sweeper, nor can they be disposed of in a general landfill site like
most swept waste. Contact the appropriate authority for the collection and disposal requirements of such
dangerous and/or hazardous material. (SWO-25)

•
SAFETY
Always wear required OSHA approved Personal Protective Equipment (PPE) when coming
in contact with and removing potentially dangerous and hazardous material that has been
collected by the Sweeper or which is obstructing one or more Sweeper components. Pay
close attention to dangerous and hazardous material including, but not exclusively limited
to, chemicals, decaying carcasses and sharp objects. (SWO-26)
SAFETY
Never sweep into hot or burning debris. A burning object, even as small as a lit cigarette,
has the potential of igniting the collected waste inside the hopper, possibly destroying the
Sweeper and inflicting serious injury or death to the operator or passersby. (SWO-27)
Verbal communication near a Sweeper is difficult and dangerous. Operating instructions
and sweeping directions should be made prior to starting the Sweeper. Unclear and
misunderstood communication may lead to operator and bystander injury or death and
equipment damage. If communication to the bystander by the operator is necessary,
completely shutdown and exit the Sweeper. Never allow anyone to approach the Sweeper
while in operation. (SWO-28)
Never allow children to play on, under, or around the Sweeper nor allow children to operate
Sweeper controls. Children can slip or fall off the Sweeper and be injured or killed.
Children can cause the Sweeper components to shift or fall crushing themselves or others.
(SWO-29)
Allow Sweeper passengers only in situations where their presence is involved in the
sweeping operation (operator training, supervision, maintenance inspection). Never carry
passengers whose presence distracts from the safe operation or transport of the Sweeper.
Passengers must be seated securely and belted in the cab’s passenger seat. Never allow
any person to ride on any other location of the Sweeper during operation or transport.(SWO-30)
Extreme caution should be used by the Sweeper operator when operating near passersby.
Stop sweeping if anyone comes within 25 feet of the Sweeper to prevent possible passerby
injury or death from being struck from a thrown object, entanglement with the brooms, or
run over. (SWO-31)
Under certain conditions, the Sweeper’s brooms are capable of propelling objects up to 25
feet. Be extremely careful when sweeping large dense objects, such as gravel or broken
glass, that might become propelled and cause bodily injury to passersby or damage to
property such as windows and vehicles. (SWO-32)
Make sure that no bystander, animal or obstruction such as a vehicle,
building, or street sign are behind the Sweeper when backing up. The design
of the Sweeper impairs operator rear vision when backing. Use extreme
caution to ensure that the Sweeper is not backed into the path of pedestrian
or vehicle traffic. Serious injury or death and property damage could result
from running into, being crushed by, or run over by a Sweeper. ( S W O - 3 3 )

Safety Section 1-10
SAFETY
Make sure no bystanders or animals are within 25 feet of the Sweeper when
dumping contents from or cleaning the hopper. Hopper contents, which may
exceed several thousand pounds, could fall and crush a bystander or an
animal resulting in possible injury or death. ( S W O - 3 4 )
Do not operate the sweeper or start the auxiliary engine with the sweeper broom cover
open or missing. The broom can throw objects or entanglement in the rotating broom can
result in bodily injures. (SWO-36)
If the sweeper is powered by CNG or other petroleum gas products, the sweeper must be
stored outside or in a properly ventilated building to prevent the build up of escaping gas.
Accumulated gas can be ignited by a spark causing an explosion. (SWO-40)
Avoid body contact with collected debris in the hopper. Use protective clothing including
gloves and eye protection when servicing or working in or around hopper.
Collected
debris in the hopper can cut or puncture resulting in serious bodily injuries and the
transmittal of diseases. (SWO-42)
Use extreme caution when operating the Sweeper in traffic. To alert motorist of the
Sweeper’s presence, the Sweeper is equipped with warning signals, flashing lights, and a
built-in arrow board. Optional electrical lights, flashers and a warning bar light, strobe, or
beacon may be positioned on top of the cab. Use all equipped warning signals to alert
motorist and pedestrians of the Sweeper’s presence and relatively slow speed. Serious
injury or death and property damage may occur if a vehicle collides with the Sweeper. (SWS-3)
Before starting a sweeping operation, make sure all the warning signal lights are
connected, visible and working. Routinely inspect the Sweeper’s headlights, brake lights,
backup lights, and turn signal lights for operational condition. Immediately repair nonfunctioning lighting. Always follow all local traffic regulations while operating the Sweeper.
(SWS-4)
Always turn on all safety lights and flashers when you operate the Sweeper. It is
recommended that you preset the beacon/strobe light switches to ON, so lights go on
whenever the auxiliary engine is ON and lights go OFF whenever the auxiliary engine is
turned OFF. This presetting action has the additional benefit of alerting the operator if the
auxiliary engine is inadvertently left ON. (SWS-5)

SAFETY
Never crawl under the hopper bin while the hopper is in the raised position unless properly
secured with the safety prop in position. Accidental operation of a lifting lever or hydraulic
failure may cause a sudden drop of the unit with injury or death by crushing. (SWM-7)
Use proper protective equipment (gloves, safety eyewear, face shield, arm protection,
possible respirator or particle mask) when handling gutter and sweeper brooms during
replacement, adjustment, and maintenance. Broom bristles, which are sharp and coarse,
could inflict puncture and stab wounds to the hands, arms, and/or eyes if proper protective
equipment is not worn. (SWM-8)
Always shut down the Truck and Auxiliary engine completely and wait for all motion to
come to a complete stop before working on any Sweeper component. (SWM-36
Escaping pressurized hydraulic oil generated by hydraulic pumps has the potential to inflict
serious injury and possible death. Never attempt to repair a pump or hose or tighten a
connection while the system is pressurized. Always shut down the Truck and Auxiliary
engine and relieve hydraulic oil pressure before performing any repairs to the hydraulic
system. (SWM-11)
Hydraulic pressure must be relieved from the Sweeper’s hydraulic circuit prior to doing any
maintenance or repair work and when the Sweeper is parked at the end of the day. Place
the Sweeper’s gutter brooms, sweeper broom, suction head, and outriggers on the ground
or securely blocked up with the safety pins installed. Make sure the hopper bin is lowered
onto the chassis or secured in the raised position with the safety prop in position. Turn off
the Truck and Auxiliary engine then engage the hydraulic remote cylinders several times to
relieve hydraulic pressure prior to performing any maintenance or repair work. (SWM-12)
Water pressure generated by the high pressure water pump has the potential to inflict
serious injury and death. Never attempt to repair a pump or hose or tighten a connection
while the system is pressurized. Always shut down the Truck and Auxiliary engine and
relieve water pressure by activating the system before performing any repairs to the high
pressure water system. (SWM-13)
NEVER work on or near any engine component that has generated heat until it has cooled
down. Use extra caution around the exhaust manifold near the water valve and the turbo
charger manifold tubes. NEVER check or replenish the fluid levels of the Truck and
Auxiliary engine coolant or hydraulic circuit oil levels until sufficient time has passed (up to
2 hours) to allow the system to cool down. Contact with a hot engine component or
operating fluid may result in serious injury from burns, scalding and possible death. (SWM-14)

SAFETY
Never crawl under any raised Sweeper component (gutter broom, sweeper head,suction
head, hopper bin) unless the component is securely supported or blocked up and hydraulic
pressure relieved. Accidental operation of the lifting lever or hydraulic failure may cause a
sudden drop of the unit with possible injury or death by crushing. (SWM-9)
SAFETY
Never remove debris from or unclog jams in the suction hoses, gutter brooms, pickup
brooms, and all other areas of the Sweeper until both the Truck and Auxiliary Engine have
been completely shutdown, all sweeping components have come to a complete stop and
are lowered to ground level and hydraulic pressure relieved. Always wear PPE when
removing collected material from the Sweeper. Serious injury or death may occur if any of
these precautions are not followed when removing plugged or jammed sweeping
components. (SWM-15)
SAFETY
Use extreme caution when working in confined areas of the hopper bin or water tank for an
extended period of time. Confined work areas may pose a danger because of the physical
constraints imposed on the body. Routinely exit the confine to stretch and correct posture
to prevent physical stress imposed on the body before bodily injury occurs. (SWM-16)
Use extreme caution when entering confined areas of the hopper bin to perform repairs,
maintenance, and cleaning. Depending on any hazardous contents and/or fumes
contained within the hopper bin, specialized Personal Protective Equipment such as a
specialized respirator, artificial oxygen source, and protective body suit may be required.
Always use the buddy system when hazardous or oxygen depleting material is contained
within the hopper. Never enter an enclosed area without Personal Protective Equipment if
contents are unknown, possible injury and death may result if required precautions are not
taken. (SWM-17)
Use extreme caution when refueling the Sweeper, fuel is highly flammable and explosive if
not handled safely. Always follow these precautions to reduce the dangers involved in
refueling:
•
Completely shut down the Truck and Auxiliary Engines before refueling.
•
Do Not refuel while smoking or near an open flame.
•
Do Not store Sweeper with fuel in the tank in a building where fumes can reach an ignition source.
•
To prevent a fire and explosion caused by static electric discharge while filling the tank, use a plastic funnel. Avoid using a funnel that has a metal screen or filter.
•
Avoid spilling fuel. Fuel is corrosive and can damage plastic and painted surfaces. Clean up spilled fuel
immediately.
•
Store fuel and all oils at a site protected from moisture, dirt, and other contaminants.
(SWM-18)
Never run the Truck or Auxiliary engine in a closed building or without adequate ventilation.
The exhaust fumes can be hazardous and deadly to your health. If it is necessary to run
the Truck engine in an enclosed area, remove the exhaust fumes from the area to the
outdoors with an exhaust pipe extension. If you do not have an exhaust pipe extension, or
if it is not possible to use one (Sweeping within a building), open doors and circulate
outside air into the area. (SWM-19)
Engine Exhaust, some of its constituents, and certain vehicle components contain or emit
chemicals known to the state of California to cause cancer and birth defects or other
reproductive harm. (SWM-20)

INTRODUCTION
The Schwarze M6 Avalanche mechanical sweeper is a heavy-duty, four wheeled,
self-propelled sweeper designed for optimum efficiency and service under varying
conditions. The sweeper is designed to be mounted on a standard production truck
chassis. Several options are available including dual steering and air conditioning.
The mechanical sweeper works by picking up the debris from the roadway and
moving it into the sweeping path, where the rear broom sweeps the debris onto a
conveyer system, which in turn carries the debris to the 5 cubic yard hopper. With
steel brooms, this equipment is made for heavy debris found on larger industrial sites,
new construction areas laden with mud and gravel and other such demanding
maintenance areas. Used extensively on highways to remove grime and debris,
mechanical broom sweepers are the workhorses of the construction and asphalt
industries. Once the material is conveyed into the debris hopper, it can be dumped
from a height range of 16” to 138”, providing maximum flexibility in your operations.
For your convenience and safety, the Schwarze M6 Avalanche sweeper is controlled via a console located in
the cab of the truck. This console allows for remote operation of the hydraulic, dust suppression, and lighting
systems, as well as the sweeper’s auxiliary engine, if in the twin engine (TE) configuration.
Your new Schwarze M6 Avalanche sweeper may also be configured in the single engine (SE) configuration. In
addition, there may be other options that would be added prior to the sweeper leaving the factory or dealer
installed. For more details about the many available options, contact a Schwarze Industries sales
representative at 1-800-879-7933.

13. GUTTER BROOM AND MAIN BROOM DOWN PRESSURE CONTROL
Broom down pressure control consists of four electronic regulators located in the rear sweeper compartment
and four switches located on the sweeper console. These four electronically controlled electronic regulators
vary down pressure on the main boom broom and gutter broom(s). The operator makes the adjustments on the
sweep screens. Adjustments range from 0-100 PSI, 0 PSI has the greatest pressure on the broom, while 100
PSI makes the broom lift off the ground.
When the sweeper is in position to start sweeping, lower the brooms by using the broom controls, Six Sense or
STANDBY. The brooms are lowered by the air cylinders that are mounted in the gutter broom mounts and the
cylinders that support the Main Broom. With the brooms on, create a scuff pattern on the pavement. Move the
sweeper enough to examine the pattern left by the brooms. Press the down pressure switches up or down to
change the pressure in each cylinder (raising the pressure reduces the down force on the booms) and the
amount of broom contact with the pavement is adjusted.

operating the sweeper perform all preparations (including daily maintenance and lubrication) and a pre-trip
inspection fulfilling DOT regulations in your area.
NOTE: If the vehicle is over 26,000 lbs. GVW the driver, in most states is required to have a CDL license.
14.1 Getting to the Sweeper Site
Before you drive:
1. Complete the Start-Up Checklist
2. Before the truck moves verify that the following conditions exist:
•
The Main Broom is fully raised.
•
The Gutter Brooms are fully raised.
•
The scissors lift and hopper is in the lowered position with the hopper door shut and latched and the
conveyer is completely seated in the hopper.
3. PTO or auxiliary engine should not be operating while in transport mode.
14.2 Sweeper Operation Sequence
The following are basic sweeping guidelines that will generally apply to all sweeping applications and will aid
the operator in becoming familiar with the sweeper and its controls.
After the engine has been started and warmed up, (oil warmed to 120º F) sweeping may be accomplished.
1. Start the engine and allow it to warm up. If the sweeper has been traveling, stop the sweeper.
2. Press the service brake and place the transmission shifter in NEUTRAL.
3. Press the PTO button to engage PTO and pumps. Allow the sweeper to roll slightly to ensure the 2-speed
axle is engaged (single engine units only).
4. Lower the gutter brooms to the pavement using the control switch(es) on the console.
5. Lower the Main Broom to the pavement with its control switch (this lowers the conveyer, drag shoes, and
dirt deflector).

Operation Section 3-20
OPERATION
6. Select and turn on the desired water spray.
7. Place the transmission shifter in FIRST GEAR.
NOTE: Engine will speed up to 900 RPM when the PTO button is engaged.l The maximum travel speed of the
sweeper while the PTO is engaged is 30 mph (Single Engine Units Only).
Be SURE the Parking brake is OFF. The instrument panel light (Parking Brake) should not be burning at this
time.
Sweeping should be done at low speeds to be effective and safe. Suggested maximum speeds for various
conditions are as follows:
1. For heavy sweeping, with dirt caked on the pavement, 1-MPH (MAY REQUIRE BRAKING).
2. For lighter sweeping, which still involves moving a lot of material, 1-3 MPH.
3. For light sweeping when only occasional dirt and light trash is encountered, 3-8 MPH.
4. The lightest sweeping, with very little dirt, can be done at 8-10 MPH. For additional information, see
Maintenance Section - Sweeping Performance Troubleshooting.
14.3 Leaf Sweeping
Left sweeping requires raising the conveyer from its normal sweeping position. The conveyer is suspended at
the rear by slotted links activated by an electrically controlled air cylinder. For normal sweeping, these links are
in the lower position. When leaf sweeping is required the conveyer can be raised three inches by activating the
conveyer raise position from the control console.
14.4 Stop Sweeping
To finish sweeping a segment of roadway:
1. Toggle the broom switches once to turn off and to raise them.
2. Turn off the water valves using the corresponding switch.
3. Continue to sweep with the Main broom for about a half a block to pick up debris left ahead of the Main
broom.
4. Turn off the front/Main broom spray water if in use.
5. Toggle the MB/Conveyer switch once to stop and to raise the Main broom and conveyer.
6. Bring the sweeper to a complete stop.
7. Disengage the PTO button (Single Engine Units Only) and allow the sweeper to roll forward to shift the rear
axle into high.
8. Shift the transmission into Drive to transport to another sweeping site or too the dump area.
NOTE: At the end of sweeping the STANDBY switch can be used to turn off water, conveyer and show all
brooms. Safety light will remain on.

Operation Section 3-21
OPERATION
If the Parking Brake light is illuminated and/or the alarm is on, DO NOT move the sweeper, i.e., “Drive-Thru”
the Parking Brake. Determine why the brake is still on and correct before trying to sweep.If the air Parking
Brake will not release, the alarm will not stop until the air system achieves 80 PSI.
OPERATION
15. DUMPING
Before you dump verify you are on a firm level surface.
Before you dump from the hopper into a dump truck always check the level of fill in the truck
bed and adjust the dump off height prior to dumping to avoid door damage.
15.1 Getting to the Dumping Site
OPERATION
Use the right side steering only for sweeping. NEVER for travel exceeding 15 MPH.
If you are operating the sweeper from the right side and the dumpsite is NOT at the sweeping site, do the
following:
1. Stop the truck in a safe area and take the truck engine out of gear (putting it in neutral).
2. Set Parking Brake.
3. Temporarily exit the cab to remove the ‘Slow Moving Vehicle’ emblem.
4. Switch driving positions.
5. From the cab console control panel, toggle warning light and safety flasher switches OFF.
15.2 Dumping Operation Sequence
Use the following procedure to empty the hopper.
1. Be sure that the sweeper is on level ground and completely stopped.
2. Shift the transmission selector to NEUTRAL (N).
3. Apply the Parking Brake.
4. Check for overhead obstructions, power lines, etc.
5. Press the PTO ENGAGE switch (Single Engine Units Only)
6. Push the HOPPER UP control switch in the console forward to the UP position.The conveyer will raise out
of the hopper and then the hopper will raise.
NOTE: The hopper will not lift or dump until the conveyer is fully raised.
7. Continue to hold the HOPPER UP switch until the hopper reaches the desired height. The hopper can be
dumped at any point from 1” the lowered resting position to full lift extension.
Do not move this equipment with the hopper raised. If you must reposition the equipment,
lower the hopper and then move the equipment.
Do not operate this equipment within 20 feet of high voltage lines, or other overhead
obstacles.
8. Push the HOPPER DUMP switch to tilt the hopper for dumping.
9. After dumping is complete, push the DUMP switch down until the hopper is fully settled on the top frame of
the lift and the hopper door is closed.
NOTE: The hopper lift must be raised slightly for the door to close.

OPERATION
10. Push and hold he HOPPER DOWN switch to the DOWN position allowing the hopper to com down and
settle onto the sweeper frame. Hopper tilt light will turn off. Continue to depress down until the conveyer is
fully seated inside the hopper.
11. Press the PTO button to disengage the hydraulics (Single Engine Units Only) or idle auxiliary engine down
and turn off.
12. Press the Service Brake, disengage the Parking Brake and select the desired transmission range to move
the sweeper.
DO NOT attempt to move until the hopper and conveyer are fully down.
Your new sweeper has been quality engineered to provide years of dependable service. By following the
procedures in this section you will maximize the life of your sweeper by minimizing rust and part abrasion.
End of shift clean up is a major factor in keeping your unit in like-new condition. Generally, a high volume of
water leans best; using a fire hose with a high-velocity nozzle is the quickest and simplest cleaning method.
Other cleaning methods include the optional high-pressure wash down nozzle or regular garden hose.
WARNINGS:
1. Exercise caution when cleaning moving mechanisms.
2. Before you begin this operation, verify that:
•
The truck is OUT OF GEAR.
•
The parking brake is ENGAGED.
NOTE: Allow at least half and hour at the end of a day’s sweeping to properly clean the unit.
3. While engines cool down at fast idle, on the cab console control panel, toggle the following switches:
•
Main broom DOWN
•
Left gutter broom DOWN
•
Right gutter broom DOWN
4. The broom are lowered.
5. After the brooms are lowered to the sweeping surface, toggle the following switches:
•
Main Broom / OFF
•
Left gutter broom OFF
•
Right gutter broom OFF
NOTE: DO NOT raise the brooms.
6. Run the conveyer as slowly as possible.
7. Thoroughly hose down the brooms conveyer flights, center dirt deflector and hopper.
NOTE: You can use the conveyer wash-down to clean the inside of the conveyer.
If clay was swept during the day, thoroughly wash it off the conveyer and flights. Clay
hardens as it dries and can break the conveyer flights during the next sweeping operation.
8. Turn the auxiliary engine OFF.

MAINTENANCE
1. PARTS INFORMATION
Schwarze sweepers are carefully designed and built with quality materials and should be maintained using
quality parts. These parts are made and tested to Schwarze specifications. Non-genuine “will fit” parts do not
consistently meet these specifications. The use of “will fit” parts may reduce the sweepers performance, void
warranties, and present a safety hazard. Use genuine Schwarze sweeper parts for economy and safety.
MAINTENANCE
2. GENERAL MAINTENANCE
In this part of the M6 Avalanche manual we include checking, adjustment and/or replacement procedures for
all major sweep systems and devices.
For some systems and devices, such as daily examination of the ‘Y’ strainer, maintenance is regular and
ongoing. For others, we include a beginning statement to tell you when adjustment or replacement is
necessary. For example, you know that right or left gutter broom dust suppression system nozzles should be
cleaned or replaced when water flow is restricted and that broom.
For many devices we also include a table of maintenance tasks and identify the section(s) of the manual to
access for related procedures.
2.1 Maintenance Logs
To help you keep your Schwarze M6 Avalanche in top operating condition, we have provided maintenance logs
for Sweeper and Truck Pre-Operation Inspection Sheets to be used before every sweepeer operation. These
forms can be found in the beginning of the Operation Section of this Operator’s Manual. Please make copies
and store them in a file to keep them accessible and clean.
• Record the sweeper identification number
• Record the date
• Checking off inspection/maintenance tasks
• Signing your name
Additionally, each form has a Comments Section for:
• Providing detailed information on a listed item
• Noting information about items not listed
• Noting additional concerns
• Specifying a needed replacement part
• Recording the date a replacement part is ordered
The completed forms can be complied in a notebook. Over time this will come to represent a comprehensive
inspection maintenance record for your sweeper.

4. CLEANING
Cleaning is an important part of any maintenance program because it extends the life of the sweeper by
reducing rust and abrasion. Additionally this gives the opportunity to inspect for any damaged or worn parts
needing service or replacement.
For a general description of cleaning procedures see Operation Section of Manual, ‘END OF SHIFT CLEANUP/MAINTENANCE”.

6. BROOMS
6.1 Broom Adjustments
6.2 Broom-To-Pavement
With the sweeper parked on a typical road surface, the parking brake applied with the engine running, and
transmission in neutral, rock the broom motor switches to their up (normal rotating) position. Allow the brooms
to sweep long enough to establish a sweep contract wear pattern on the pavement.
Shut off the broom motor switches, raise the brooms and inspect the contact areas of all brooms. The gutter
brooms should form an arc pattern in the positions show. The rear (pick-up) broom should form a rectangular
pattern that measures 4-6 inches. The gutter brooms should measure 4 inches.
NOTE: The main broom contact pattern must measure the same all the way across the pattern or “Coning” of
the broom will occur.

Maintenance Section 4-7
MAINTENANCE
A daily inspection of the brooms is essential to prevent premature and uneven wear. Broom-to-pavement
contact patterns are observed to determine the need for adjustment.
1. Gutter broom adjustments include:
A. Pressure adjustment
B. Tilt adjustment
2. Main (pickup) broom adjustments include:
A. Main broom suspension chain
B. Main broom drive chain adjustment
MAINTENANCE
6.3 Gutter Broom Adjustments
MAINTENANCE
Downward pressure is exerted by the weight of the broom itself. The downward pressure can be reduced by
decreasing the air pressure setting in the gutter broom air suspension cylinders.
6.4 Down Pressure Air Adjustment Flotation
The gutter broom down pressure adjustment is done “From the Cab” by the gutter broom down pressure
adjustment switches. To increase broom down pressure, press and release the bottom side of the switch. This
will decrease pressure in 1-2% increments. Low broom down pressure will result in higher pressure on the
pavement. Zero (0) psi is maximum down pressure. One hundred (100) psi will lift the broom off the pavement.
NOTE: New gutter broom bristles are approximately 13 inches long. A broom is considered worn out when the
bristles are only 5 to 6 inches long.
NOTE: Too much downward pressure on the broom, when it is not needed, causes premature wear of the
bristles.
NOTE: Propulsion engine must be running and system air pressure must be achieved.
6.5 Tilt Adjustment
The tilt of the gutter broom is adjustable so that despite the sweeping conditions, the gutter broom will throw
debris squarely against the center dirt deflector for the most efficient sweeping. If the outward tilt is too great,
debris is thrown ahead of the dirt deflector and it the tilt is too little, debris is thrown too far back under the
sweeper and misses the dirt deflector.
To adjust tilt, loosen both lockouts, loosen tilt-adjusting rod, push or pull broom to desired tilt, tighten adjusting
rod and then tighten lockouts.
Optional Hydraulic Gutter Broom Tilt:
To adjust tilt the gutter broom must be running, actuate the gutter broom tilt switch on the operators control
console until the desired amount of gutter broom tilt is achieved.
NOTE: Prior to raising the gutter broom return the broom tilt to a neutral position as brooms in the extreme
condition may cause the broom bristle to contact the pavement during transport.

MAINTENANCE
6.6 Gutter Broom Segment Replacement
To repair or replace segments containing worn bristles, perform the following steps:
For disposable type:
1. Remove the worn segments from the mounting plate by unscrewing the bolts that hold each segment to its
mounting plate. Replace disposable segments with new ones.
2. Adjust the gutter broom air suspension for the increased weight of the refilled broom.
During sweeping, the gutter broom(s) will rotate in a clockwise fashion. However, rotation of the gutter
broom(s) may be reversed so debris is thrown outward, instead of in under the sweeper for certain applications
(for example, to spread material or to sweep debris off curb-tops or road shoulders).
Never reverse the direction of the gutter broom(s) rotation with the broom(s) in motion.
To set the gutter broom for reverse rotation:
1. Press the reverse side of the gutter broom switch on the operator console (See figure shown to right).
Broom will lower to pavement.
2. A message shows up on the operator screen to pin gutter broom, then acknowledge that broom has been
pinned. Place the reverse pin through the holes that line up in the motor mount and gutter broom mounting
plate. Once the appropriate broom(s) have been pinned, acknowledge the on-screen prompt by pressing
the “F6” button on the display.
3. Press the reverse side of the appropriate gutter broom switch to start the broom running in reverse.
4. When finished sweeping, press the reverse side of the appropriate gutter broom switch. The broom will
stop rotating, and a message to unpin the gutter brooms will display. Unpin the brooms and stow the
reverse pin. Once all brooms are unpinned, acknowledge the on-screen prompts by pressing the “F5”
button on the display.
When sweeping with the gutter brooms in their normal direction of rotation, their centrifugal force keeps them
pulled away from the sweeper, thus, it is not necessary to lock them in place except for reverse sweeping.
When not in use, stow the reversing pin in the hole provided for this purpose.
Never retract the gutter broom when the reversing pin is in place. The pin blocks the
retracting mechanism and the resulting strain is very likely to damage part of the gutter
broom assembly. Be very careful not to bump anything while the gutter broom is running in
reverse, because it is now essentially a rigid unit. The forward motion of normal use pulls the
gutter broom from under the sweeper and it bounces back under the sweeper if it strikes
anything. This cushioning effect is absent in reverse rotation.
6.8 MAIN BROOM ADJUSTMENTS, AIR SUSPENSION
The main broom is floating on two air cylinders, one on each end, that are pressure regulated using the control
switches located on the in-cab console. Separate regulators are used to control slightly different pressures, if
needed, to maintain a good 4 - 6" pattern with the main broom. Zero (0) psi is maximum down pressure. One
hundred (100) psi will lift the broom off the pavement.
6.9 Main Broom Alignment
The main broom should be aligned so that there is 1/8-3/16" clearance between the end plates on the broom
and conveyer sides and even gap between the broom struts and guide bars. This is accomplished by setting
the gap between in place and locking in place using the set screws on each bearing lock collar on the broom
core shaft between the bearing and the end plate.

MAINTENANCE
6.10 Main Broom Replacement
When worn brooms become too short to exert sufficient down-pressure for satisfactory operation, broom
replacement is necessary.
NOTE: The main broom, core, and shaft should weigh approximately 225 lbs. Other brooms that are available
to use, as replacements must be able to meet above weight requirements of the geometry of the air support
mechanism will be ineffective.
To replace the main broom, perform the following steps:
MAINTENANCE
1. Lower the main broom.
2. Remove the main broom drive coupling guard.
3. Unbolt the main broom drive coupling lock collars and set aside.
4. Remove the half of the main broom drive coupling closet to the broom.
5. Remove the four bearing bolts from the bearing on each end of the broom shaft and let the broom drop or
be pulled away from the broom arms.
On “Compression Lock” cores
1. 1. Remove fiber-retaining end plate from one end of the core by removing the four flat head Allen screws
holding it in place.
2. Loosen the three Compression Lock Allen screws on each end of the core. This will allow the compression
disc to relax and loosen the core from the tube on which the broom is wound.
3. Pull the compression lock core out of the worn broom.
NOTE: On “tufted” type (18 removable segments) it is not always necessary to remove the broom from the
sweeper. Simply remove the four bolts holding fiber retaining plates on the RH side of the broom and slide the
segments out of the mounting tracks.
Install the Compression Lock core in the new as follows:
1. Insert the Compression Lock core into the new broom all the way, using the fiber-retaining end plate as a
stop.
2. Finger-tighten the three Compression Lock screws on each end of the core. Using the Allen wrench tighten
each screw one-quarter turn, progressively. Repeat, in quarter-turn increments, until the screws are finger
tight. This should require about (3/4) three quarter-turns on each screw. (Do not over-tighten by using an
extension on the Allen wrench). This should be equivalent to about 30 foot-pounds of torque on each screw.
3. Attach the fiber-retaining end plate to the end of the core from which it had been removed.
4. On the wafer style brooms, The broom retainer plate is also removed from one end. Worn wafers can then
are removed and new wafers installed. Replace the broom retainer plate.
5. The main broom is ready for installation on the broom arms by replacing the spacers, bearings, sprocket
chain, and cover.
7. CONVEYER
7.1 Conveyer Adjustments
Use the following guidelines to determine when an adjustment is needed and how to accomplish it.
Flight Chain Adjustment
When flight chains have stretched to a point where the top strand is sagging near or touching the bottom
strand, use the adjusting bolts on each side of the elevator, maintaining equal spacing of the upper and lower
elevator shafts.
M6 Avalanche 09/13
©2014 Alamo Group Inc.
Maintenance Section 4-10
MAINTENANCE
Flight Chain Adjusting Cylinder
NOTE: When shortening the chains or installing new chains, it will become necessary to remove the grease
fittings from the chain adjusting cylinders and push the old grease out of the cylinders by retracting the cylinder
rods.
Conveyer Flight Adjustment
1. The new rubber flights should be just touching the floor of the conveyer or up to 1/16” off the floor as they
come around the top sprocket. The flights will wear and start leaving the floor farther down the floor plate.
As the flights wear clearance can reach up to ½” before adjustment is required. As long as good discharge
into the hopper is occurring, there is no need to make unnecessary adjustments just to maintain this
clearance. Depending upon the material being swept, ¼" to ½" wear of the rubber can occur before
adjusting.
NOTE: Smaller clearance must be kept for best
results, when sweeping extremely wet material.
M6 Avalanche 09/13
©2014 Alamo Group Inc.
Maintenance Section 4-11
MAINTENANCE
Watch the flight chain as you extend the adjusting
bolt. Take about 1” of sag out of the chain on each
side, moving from side to side until the chains are 3”
apart.
A worn chain becomes longer and adjustment will
prolong the life of the chain. The right hand chain
will usually
wear faster than the left, so the right hand sag kept
the same as the left will start to push the right hand
top sprocket ahead of the left sprocket. At some
point during the chain adjustment, check the
distance between the top and bottom shafts. Do not
allow these two shafts to become more than 3/8”
farther apart at the sprockets to prevent excessive
wear on the chain and sprockets. When the chains have become worn enough to use the maximum 3/8”
difference in shaft centers, less than 3" sag on the longer chain will operate until the need for adjustment again.
At that time, shortening the chains by a half-link and swapping sides with the chain (putting the left on the right
and vice-versa) will extend the life of a set of chains.
MAINTENANCE
2. Make any needed flight adjustments at the same
time as one of the chain adjustments. Start the
chain adjustment procedure as described above
and when the chain sag is 1-1/2” to 2” stop and
adjust the flights to the floor plate. Adjust the
rubber flights as follows:
A.
MAINTENANCE
B.
C.
Turn conveyer until a flight is under the
sprockets of the top shaft
Loosen the bearing bolts and using a pry
bar in the top of the conveyer and against
the shaft, move the bearing along the slot
until flight rubber is touching to 1/16" off
the floor of the conveyer.
Snug the bolts and adjust the other end of
the shaft. Check both ends for proper
adjustment and tighten the bearing bolts.
3. The bottom shaft is adjustable in the same
manner, but the need for adjustment is even less frequent than the top shaft because material pickup is not
greatly affected until considerable flight wear has taken place. Flight replacement may be the only
adjustment necessary at the bottom shaft. After worn flights are adjusted or when new flights have been
installed, finish the flight chain adjustment to the proper sag of 3". The flight adjustment to the floor will be
easier if this adjustment is made before the chains are fully tightened.
7.2 Conveyer Height
The conveyer-to-pavement relationship is set by the slotted links that suspend the rear end of the conveyer.
Normal sweeping height of the lower edge of the conveyer floor plate off the pavement is approximately six (6)
inches. Actuation of the in-cab control of the conveyer raise switch will raise the conveyer by 3" yielding a total
9" of clearance. This is especially helpful when sweeping bulking materials such as leaves.
7.3 Conveyer Stall
The conveyer has a stall detection system that will indicate when the conveyer has slowed or stopped. A
pressure switch will enable an alarm to display. This alarm is located on the monitor (HMI) screen. An optional
audible alarm may also sound when a stall condition occurs.
With the monitor set the conveyer will run from a normal speed no indication of slow down or stall will occur. If
the conveyer pressure increases to pre-stall levels an alarm will sound.
If, during heavy sweeping with the conveyer really working hard, the light and alarm come on, then the
overload condition exists and the operator can slow the sweeper to allow the conveyer to clear itself.
The monitor is indicating that the shaft speed has dropped and the motor is on around 2900 psi operating
pressure which could mean that the conveyer is completely stalled. If slowing the sweeper for a few seconds
does not allow the conveyer speed to pick back up (light and alarm will go off), stop the sweeper and reverse
conveyer by pushing the CONVEYER REVERSE switch. This switch operates the main broom and conveyer
for sweeping and will re-verse the conveyer, but does not reverse the main broom. Reversing the conveyer will
usually clear the obstruction.
If reversing the conveyer does not clear the obstruction, then removal by hand is necessary. Switch off all
broom and water functions, place the transmission in the Neutral position, apply the parking brake, and allow

the engines to idle for 2-3 minutes to allow essential cooling before turning off the ignition and secure the keys
for safety.
Never attempt to inspect or work on the conveyer while the engine is running.
Remove the cover above the conveyer to determine the cause of the stall.l Carefully dislodge and remove any
jamming object. Check for any damage: bent flights, broken chain, etc. Make any repairs necessary and check
the conveyer for needed adjustments.
Be sure that the wiring is correct.
The pressure switch is factory set at 2900 PSI, and should not need adjustment.
8. HOPPER MAINTENANCE
If you are not familiar with the hopper system and its operation see Sections Hopper Dump and Hopper
Operation.
The hopper is a simple component and needs little in the way of maintenance. Clean the hopper daily to
prevent debris build-up and follow the Lubrication Schedules.
8.1 Hopper Replacement
Hopper replacement is a big job, and for that reason we have separated the process into the categories of
Preparation, Disassembly, Removal, and Replacement.
You will need for this replacement:
• Two workers
• Overhead crane
• Support blocks
Removal
To remove the hopper.
Preparation
1. Lower the hopper door and remove the access cover located on the hopper floor center adjacent to the
hopper dump door hinge.
2. Raise the hopper just above the cab line inches and place blocks in the scissors lift slides to support the
scissors lift.
3. Lower the hopper onto the support blocks.

5. Use the crane to lift the hopper clear and set to the side.
6. Replacement
7. Reverse the above order to re-install the hopper.
8. Lift the replacement hopper into position aligning the hopper pivot eyes. Drive the hinge pins back into place
through the hopper and the top of scissors frame.
9. Replace the original bolts and retaining washers in the ends of the hinge pins.
10.Reconnect the hydraulic hoses and electrical connections under the access plate and install access cover.
11. Swing the tilt cylinders into position and reconnect the cylinders to the hopper with pins.
12.Unchain the hopper from the crane and move to the side.
13.Start the engine (See Section Auxiliary Engine Start-Up) and lift the hopper so the safety props on the frame
can be removed.
14.Lubricate the grease fittings on the cylinders and hinges. (See Section Weekly Lubrication Points).
NOTE: If your unit is equipped with the optional Auto Lube System, actuate the system to assure the
lubrication points have received lubrication prior to the timer setting.
9. HYDRAULIC SYSTEM MAINTENANCE
System Description:
The system consists of:
1. A hydraulic tank with a 35 gallon capacity. Tank s considered full when the oil level mark is at the 120ºF
point on sight glass with the hopper lift in the down position.
2. A 10-micron filter element with 25 psi bypass.
3. An oil cooler located inside the rear compartment with an electric fan that is controlled by the sweeper
console power. The fan will come on when the console is powered up and the hydraulic oil reaches 120ºF.
4. Hydraulic motors and cylinders that are industry standard mobile hydraulic components.
Hydraulic Reservoir
The hydraulic reservoir for the Twin Engine is located in the center of the rear compartment of the sweeper
behind the water tank. At least once a year or 2000 hours drain and clean the hydraulic reservoir. Change
filters at 400-hour intervals.
NOTE: Change filters after the first 50 hours of operation and every 400 hours thereafter or after a component
failure. Change oil in addition to filters after a hydraulic component failure. Operational service includes
maintaining the proper level of hydraulic oil, keeping the oil clean and keeping the system’s exterior surfaces
free of dirt to promote easier detection of wet lines, bolts or oil leaks.

Maintenance Section 4-14
MAINTENANCE
Following are the basic points of maintenance and service for the fluid reservoir and filter.
1. A daily check of the hydraulic oil level is essential, by viewing the reservoir sight gage. Remove the fill-cap
and add fluid (See Lubrication Chart) from a clean, previously unopened container.
2. Regularly inspect the condition of the entire system checking for leaks, cracked valves, fitting or chaffed
hoses.
3. Change the hydraulic oil and filters at the recommended intervals listed above:
B.
C.
Drain Reservoir - The drain for the reservoir is a pipe plug located underneath the hydraulic tank. To
drain this reservoir, simply remove the pipe plug and let the oil flow out into a suitable disposal
container. The reservoir holds approximately 35 gallons.
B. Remove Filter - Remove the cover from the filter housing, then gently remove the element from
inside the housing to avoid depositing any contamination inside the filter housing. Single Engine
filters are spin off filters located in the rear compartment.
Refill - Replace the elements and cover, and refill the reservoir with hydraulic fluid as necessary.
NOTE: For operating in 0ºF below, fill hydraulic system with Tellus 32 or equivalent. For normal operating
conditions use Tellus 68 or equivalent.
The main hydraulic system consists of a single variable displacement piston type pump and electric control
valves. The control valves are responsible for raising and lowering the hopper and all broom functions.
The pump is located behind the transmission and is driven by a PTO mounted on the transmission on single
engine (SE) units.
The pump is mounted to the rear engine bell housing and is driven by the rear engine on twin engine (TE)
units.
NOTE: When removing the pump, be extremely careful to keep all the parts clean and free from any
substances, which might contaminate the hydraulic fluid. Failure to comply may void warranty.

sweeper. The working pressure of any function can be measured from this port.
Main Pump Settings:
1. Standby Pressure is 500 psi (900 psi on TE)
2. Maximum Compensation pressure is 3200 psi.
MAINTENANCE
When testing for pressure and flow, be sure the oil temperature is 120ºF and the engine speed is 900 RPM
(2200 RPM for the twin engine).
NOTE: The broom system pressure should never exceed 1500 psi when testing brooms on smooth concrete
while the sweeper is stationary. If it does, the broom down pressure or standby pressure could be too high.
Compensation Pressure
The compensation pressure is the maximum pressure produced by the pump. This setting is adjustable and is
called the Compensation Setting.
Broom Compensation Pressure
The broom pump should have a compensation setting of 3200 psi. To measure the compensation pressure the
engine is on, the park brake is engaged and the transmission is in neutral.
1. Turn all brooms off.
2. With all brooms off, raise or lower one of the gutter brooms.
3. When the cylinder has reached the end of its stroke the pump will go to full pressure (compensation) and
the pressure displayed on the gauge will be the compensation setting.
4. To adjust the compensation setting, locate the adjustment screw on the lower left-hand side of the pump (a
hex head adjustment knob). Loosen the locknut and turn the screw clockwise until the correct compensation
setting is achieved.
Standby Pressure
The standby pressure is the pressure generated by the pump when all hydraulic functions are off.
Broom Standby Pressure
The standby pressure in this system is the pressure drop between the pump and the load. The pump would
have a standby pressure of 500 psi, which is set at the pump.
NOTE: When measuring standby pressure, all hydraulic functions must be turned off.
The broom circuit “Load Sense” system for all broom functions. A series of shuttle valves delivers a signal to
the broom pump to come on, stroke, and deliver the needed flow and pressure.

13. ELECTRICAL SYSTEM MAINTENANCE
In order for the electrical system to continue to function properly, it is important that the electrical wiring and
components be protected from abuse that could cause premature deterioration. This can be accomplished by
conducting periodic inspections of the system and repairing any defects noted. The following should be
included in such an inspection:
1. Check all wiring for damage that could cause a short circuit.
MAINTENANCE
2. Check for loose connections at components and mating harnesses.
3. Check for broken or improperly secured wires.
4. Check for blown fuses (if applicable) and/or tripped circuit breakers.
5. Check battery, mounting and connections to make sure proper voltage is being supplied.
6. Make sure components remain clean and free of dirt, fuel, water or other components.
NOTE: Although it may be desirable to perform some trouble shooting checks with the electrical system
energized, it is suggested that the negative battery cable be removed prior to performing work on components.
This will reduce the chance of accidental arcing that may cause damage to components or injury to personnel.
13.1 Introduction
The electrical system requires minor maintenance to keep it functioning. The batteries located under the cab at
the right will need periodic inspection The circuit breaker panel is in the front of the console.
13.2 Fuses
The control system utilizes a multiplexed Cooper Bussman module, located in the box on the RH truck body
door. It contains fusing to power the controller, the console, and other high current devices located on the
sweeper. Inline fuses are also included vendor furnished components. Always replace fuses with the same size
and type of component.
13.3 Circuit Breakers
The power in the console is protected using thermal type self-resetting circuit breakers. These circuit breakers
are located inside the in-cab console. All power to the sweeper is provided using a constant duty power
solenoid, located on the side of the battery box. This solenoid is energized when the chassis key switch is in
the RUN position.
A.
B.
C.
If a breaker kicks out wait for reset and continue to operate. A malfunction in that circuit is usually the
cause of the breaker kicking out and will happen again. If it does, check out that circuit to see what is
causing the overload.
If after inspecting wires, connections, etc., nothing can be found in the circuit to cause a problem,
check the amperage of the circuit at the breaker. Excessive draw still indicates a circuit problem
internal in a component, etc.) and the problem must be identified and corrected.
If the load at the breaker is at or below the rating of the breaker (rating is shown on the breaker) then
the breaker is faulty and must be replaced.
13.4 Rocker Switches
Most of the manually controlled switches are located in the rocker switch panel. These switches are powered
either directly from a circuit breaker or indirectly through an appropriate relay.
Most of the manually controlled switches are located in the in-cab console. These switches act as input devices
to the control system and do not directly power output devices. Possible exceptions are dealer installed options

such as extra lighting or a front cab mounted magnet. All switches in the console are three position momentary
switches. They are all OFF in the center position.
Two-position OFF/ON switch powered by the appropriate circuit breakers. The switch indicator light illuminated
when the switch is ON. All are powered only when the ignition switch is in the RUN position.
Level Sensing Switches
Low Water Level
The water level sensor, mounted inside the water tank on the right side, contains a reed switch that is activated
by a magnetic float. The switch provides a ground to the control system in-out and will cause a visual alarm to
display on the HMI. Gages are powered through the panel lights circuit breaker and read once grounded.
Hydraulic Oil Level
The oil level sensor, mounted inside the oil tank on left side, contains a reed switch that is activated by a
magnetic float. The switch provides a ground to the ground system input, and will cause a visual alarm to
display on the HMI. When the alarm is displayed, the control system will shut down the PTO function (SE) or
Auxiliary Engine (TE) if the oil level is below safe operating levels.
Proximity Switches
There are four proximity switches located on the sweeper. They provide inputs to the main controller to enable
and disable functions. They have two sets of light on the body itself. Green lights indicate that the switch has
power supplied to it. Amber lights indicate that the switch is sensing the correct position, and an input is being
supplied to the control system. They are located on the following places:
1. Conveyer In Prox:
This switch is located on the passenger side of the sweeper, mounted to the scissor manifold tower. This switch
provides feedback that the is fully seated into the hopper and is in the sweep position.
2. Conveyer Out Prox:
This switch is located on the drivers side of the sweeper, mounted to the truck body frame with a bracket. This
switch senses that the conveyer is in the back position, allowing the hopper to be raised.
3. Hopper Down Prox:
This switch is located under the hopper, on the drivers side of the sweeper. This switch senses that the hopper
is in the fully seated position.
4. Hopper Door Prox:
This switch is located inside the hopper and senses that the hopper door is in the closed position. When the
door is open, an audible alarm will sound.
Relays
For control and/or electrical load purposes, the sweeper is equipped with several coil-operated relays. Relays
are located inside the cab console on the fuse blocks.

MAINTENANCE
Various level sensing switches are installed for controlling specific functions and indications:
MAINTENANCE
There are two relays located inside the console. These relays are used to control cab mounted lighting options
(LED beacons, barlights, or strobes).
Relays are also contained in the MVEC, or Multiplexed Vehicle Electronic Controller, that is located inside the
drivers side fender of the sweeper. This MVEC is used to power the following items: 2 oil cooler fans, the water
pump and it’s three solenoid valves, the auxiliary engine starter and fuel pump. Each relay is individually fused
for circuit protection.
MAINTENANCE
Solenoid Valves
Many sweeper functions are controlled by electrical solenoid operated valves:
Sweeper functions are controlled via three manifolds located on the sweeper. All functions are controlled via
cartridge style hydraulic valves for increased reliability and fewer leak points. Cylinder functions are controlled
using 4 port, 3 way valves, while motor functions are controlled with 2 port valves. Reversing functions are 4
port, 2 way valves.
Valves are controlled electrically by solenoids activated by the appropriate signal from switches Relays etc.
Although the solenoids vary in configuration troubleshooting is to be accomplished. Generally by checking to
see if the solenoid shifts the valve when energized. Similar to a relay a CLICK can be heard if the valve is being
shifted by the solenoid. Another check for the solenoid coil is to perform a continuity test across the coil wires.
Lack of continuity indicates coil failure. Replace the solenoid coil. Sometimes solenoids fail to operate due to a
poor ground. Verify that a sufficient ground is present.
Fans
The following fan/blower is installed:
Hydraulic Oil Cooler
Included as part of the cooling coil assembly, located in the rear compartment, this fan is activated when the
sweeper control console is energized and the oil reaches 110ºF operating temperature.
Visual Alarms
Visual indicators and alarms are located on the monitor (HMI) screen and are displayed when alarm conditions
are met or when certain sweeper functions are operated.
Diodes
Refer to wiring schematics for functions of various diodes in the electrical system. These are provided to block
flow in a reverse direction in a circuit, for whatever reason necessary. Failure of a diode is usually evident when
signals that are blocked in one direction normally will either fail to operate or will allow current to flow in the
undesired direction. If this occurs replace the diodes as needed.
Water Pump(s)
The water pump(s) is mounted in the rear engine compartment. They are powered from MVEC. Power is
available while sweeping except when the EMPTY light is illuminated on the water level panel. This is done to
protect the pump(s) from being run dry.

MAINTENANCE
Temperature Sensing Switches
Temperature sensing is done using an analog temperature probe located inside the hydraulic tank.
Temperature is fed into the main controller and is used to control various alarms, gauge, and engine shut down
sequences. Hydraulic oil cooler fans are set to turn on at a temperature of 110 degrees F. High oil temp
shutdown occurs at 190 degrees F.
14. DUST SUPPRESSION SYSTEM MAINTENANCE
You refill the water reservoir using the 25-foot hose stowed in fill hose box directly behind the right-hand rear
fender.
To fill the water reservoir:
1. Attach the hydrant fill hose to an approved fill source.
2. Turn the 2-1/2” hydrant hose and allow the water to run for a short interval so any rust and/or sediment
trapped in the water line can be cleared.
3. Attach the hose to the end of the fill pipe located under the right hand access door.l This pipe feeds the airgapped fill opening of the reservoir.
4. Allow the reservoir to fill until water gushes from its overflow.
14.2 System Winterizing
Freezing weather calls for complete drainage of the system.
1. Open front sprays bar valves, drain the tank, remove discharge line from the pump and run the pump to
clear it of any water.
2. Remove the strainer cap and stainer and leave them off until time to re-fill the tank.
3. Running the pump until clear will not completely empty the tank (pick-up tube is 1-2 inches off the bottom),
but this amount of water when frozen will not harm the tank.
4. Attach an air hose to the water valve using the air nipple provided. Turn on all water nozzles allowing the air
pressure to force any residual water out of the system.
5. Remove water cap and actuate flusher/fill valve several times to drain any trapped water from the fill pipe or
flusher cap. Reinstall.
In addition to the above, check the spray system for any low places where water might be left
standing. Drain or blow out any of these parts.
14.3 Water Manifold Solenoid Cleaning
The water manifold solenoid should be cleaned when one of the following conditions exists:
• Water leaks (perhaps even sprays weakly) from nozzles for that solenoid, indicating that the solenoid does
not fully close.
• Little or no water flows from the nozzles for that solenoid, indication that the solenoid does not fully open.
NOTE: Before you use the following procedures, thoroughly check the following:
•
•
Electrical circuit related to th faulty valve
Possible clogged nozzles
Never use ANY type of cleaning fluid to clean the solenoid valve plunger assembly or seals.

MAINTENANCE
Make sure all electrical current and pressures are OFF before you begin this procedure.
To clean the solenoid valve:
MAINTENANCE
Examining the Inside of the Valve
1.
2.
3.
4.
•
Shut OFF all electrical current and pressure.
Remove the nut at the top of the solenoid valve.
Remove the nameplate, coil and housing from the body.
Choose one:
If the valve is NOT leaking from the seat and the plunger does NOT stick in the energized position, the
problem is electrical.
• If the valve IS leaking from the seat or the plunger DOES stick in the energized position, proceed to the
next step.
Examining the Sleeve Assembly
5. Use a wrench to remove the sleeve assembly.
6. Examine the soft inserts in the plunger for evidence of dirt and/or wear.
7. Examine the inside of the sleeve assembly for evidence of dirt and/or debris.
Cleaning or Replacing the Faulty Part
8. Choose one:
• If the inserts show excessive wear, you must replace the plunger.
• If the valve emits a loud buzzing noise, examine both the inside of the sleeve and upper portion of the
plunger and remove all foreign matter.
Be careful not to damage the sleeve seat or plunger face If you mark either surface, you
must replace the entire sleeve and plunger assembly.
If you must remove the entire valve assembly from the line, be very careful during
reconnection that foreign matter gets into the valve. Pipe-thread chips in either the seat or
the soft insert will cause valve malfunction.
NOTE: Order replacement parts bearing the valve number, voltage, and frequency specified on the name
plate.
9. After part cleaning or replacement, verify that both the flange seal and the return spring are in place.
Reinstalling the Valve
10.Loosely screw the sleeve assembly into the body.
NOTE: Do not connect the valve to the electrical circuit.
Checking for Leakage
11. Before you tighten the sleeve assembly to the body, choose one:
• If the valve has a sleeve port, cap the port and apply pressure to the port leading to the body chamber.
• If the media is air or gas, apply water to the joint and watch for air bubbles.
12.Reattach the name plate, coil, and housing to the body.
13.Carefully tighten the nut at the top of the solenoid valve.

MAINTENANCE
NOTE: Excessive tightening of the nut can cause unnecessary strain on either the sleeve assembly or the coil
under the housing.
Restart electrical current and pressure.
14.4 Water Pump Maintenance
The unit is equipped with an electrically driven diaphragm pump:
NOTE: Set water pump relief over 50psi with all spray nozzles in the off position. Do not set at a higher
pressure. This can damage the pump.
To maintain the pump:
6. If freezing temperatures are expected, (See Section - Dust Suppression System Winterizing)
14.5 Nozzle Cleaning & Nozzle Replacement
A dust suppression system nozzle needs cleaning when it is clogged and water flow is restricted.
Due to dusty conditions encountered during sweeping operations, dirt and debris particles entering the dust
suppression system are sometimes small enough to pass through the Y strainer. These particles can build up
within a nozzle’s openings, restricting water flow. When this occurs, the nozzle must be cleaned or replaced.
Besides the seven nozzles located in the front spray bar mounted to the front of the truck, three nozzles are
mounted in front of each gutter broom. Additionally, an optional rear spray broom containing five nozzles can
be mounted to the conveyer frame just in front of the main broom.
To clean or replace the nozzle.
1. Remove the spray tip.
2. Wash the strainer and examine it.
3. Wash the spray tip and examine it.
4. Choose one:
• If the spray-tip opening is clogged, insert a small-gauge wire into the spray-tip opening to clear any debris
lodged inside.
• If the spray tip is damaged, get a new one
5. Reassemble the nozzle, replacing any damage parts as necessary.
