HIGHWAY AND TRANSPORT OPERATIONS:
Adopt safe driving practices:
Always drive at a safe speed relative to local conditions and ensure that your speed is
low enough for an emergency stop to be safe and secure. Keep speed at a minimum.
Reduce speed prior to turns to avoid risk of overturning.
Avoid sudden uphill turns on steep slopes.
Always keep the power unit in gear to provide engine braking when going downhill. Do
not coast.
Do not drink and drive!
Comply with state and local laws governing highway safety and movement of farm machinery on public roads.
Use approved accessory lighting, flags and necessary devices to protect operators of other
vehicles on the highway during daylight and nighttime transport.
The use of flashing amber lights is acceptable in most localities. However, some localities
prohibit their use. Local laws should be checked for all highway lighting and marking requirements.
When driving the Stinger on the road or highway under 20 M.P.H. at night or during the
day, use flashing amber lights and a slow moving vehicle (SMV) identification emblem.
Plan your route to avoid heavy traffic.
Be a safe and courteous driver. Always yield to oncoming traffic in all situations, including
narrow bridges, intersections, etc.
Be observant of bridge's load ratings. Do not cross bridges rated lower than the gross weight
at which you are operating.
Watch for obstructions overhead and to the side while transporting. Know the height of your
load and overhead obstructions.
Always position equipment in a position to provide maximum visibility at all times. Make
allowances for increased length and weight of the equipment when making turns, stopping
the unit, etc.
January 2005 ——————————————————— Section 1-7
———————————————–——————– STINGER
PERFORMING MAINTENANCE:
Good maintenance is your responsibility. A poorly maintained machine is an invitation to
trouble.
Make sure there is plenty of ventilation. Never operate the engine in a closed building. The
exhaust fumes may cause asphyxiation.
Be certain all moving parts have come to a complete stop before attempting to perform
maintenance of your machine.
Do not attempt to service the machine with the engine running. Always have the lift arm &
tilt assembly, hoist and stack frame assembly, and tailgate assembly at the fully lowered
position and the engine shut off before servicing equipment.
Before working on this machine, stop the power unit, set brakes, disengage the hydraulic
power drive, shut off the engine and remove the ignition keys.
With the ignition key on, hydraulic components can move by pushing a joystick button
even without the engine running.
Do not use the loader as a "jack" for servicing of the Stinger and/or power unit. Use only
equipment intended for such purposes with additional support blocking to retain it in the
raised position.
Always use a safety support and block the wheels. Never use a jack to support the machine.
Always use the proper tools or equipment for the job at hand.
Use extreme caution when making adjustments.
Follow the torque charts on pages 5-2 & 5-3 of this manual when tightening bolts, nuts,
fittings, and hoses.
Never use your hands to locate a hydraulic leak. Use a small piece of cardboard or wood.
Hydraulic fluid escaping under pressure can penetrate the skin.
When disconnecting hydraulic lines, shut off hydraulic supply and relieve all hydraulic
pressure.
Openings in the skin and minor cuts are susceptible to infection from hydraulic fluid. If injured by escaping hydraulic fluid, see a doctor at once. Gangrene can result. Without
immediate medical treatment, serious infection and reactions can occur.

GENERAL OPERATION:
ALL OPERATORS SHOULD READ THE MAINTENANCE AND SAFETY SECTIONS OF THIS MANUAL BEFORE OPERATING THE MACHINE.
Before starting the engine on the machine, a visual inspection should be made of the whole
machine including hydraulic components and hoses to make sure that all are in working
condition.
At this point the hydraulic reservoir should also be checked so that adequate fluid level is
maintained.
Check the whole unit for any damage or wear.
When picking up bales or sliding bales off, the speed of the machine should be approximately 3-5 mph.
When spearing a bale make sure the lift arm assembly and tilt assembly are fully lowered.
To avoid possible contact between the spear assembly and the ground while crossing uneven terrain, always carry the lift arms in a partially or fully raised position until just before
spearing the bale.
If you have speared the bale more than 10 inches off center, DO NOT operate on hillsides
or brake while backing with the front of the truck swinging to the overhanging side. If you
spear the bale more than 20 inches off center put it down and spear it again.
Acceleration of the machine as the first bale is sliding towards the tailgate may cause excessive bale speed, which may damage the bale or the tailgate.
Lower the lift arm assembly enough to pull spears from last bale just before sliding bales off
or just before sliding top four bales into stacking position.
When sliding bales off make sure the tailgate is fully lowered.
When sliding bales off, as the tailgate becomes fully lowered accelerate machine to enhance
unloading.
Wet bales will not slide on bare un-oiled metal rails, do not load bales that are wet on top
unless using the slide oiler and the rails have been oiled. (see Adjustments on pg. 3-7 for
more information)
Some models may have options that need further explanation and adjustments. (see
Options and Adjustments pages 3-6 thru. 3-8)
January 2005 ——————————————————— Section 3-1
———————————————–——————– STINGER
OPERATION OF STINGER STACKER:
ALL OPERATORS SHOULD READ THE MAINTENANCE AND SAFETY SECTIONS OF THIS MANUAL BEFORE OPERATING THE MACHINE.
MAKE SURE STACKING AREA IS CLEAR OF ALL PEOPLE AND ANIMALS
BEFORE STACKING WITH THIS MACHINE. STACKS FALLING BECAUSE OF
UNEVEN GROUND OR SOFT BALES COULD SERIOUSLY INJURE OR KILL
BYSTANDERS.
When loading bales put the bale stop up after loading the first half of load.
Start your stack 1/2 or 2/3 the full height or against backstop before going to full height.
Stacking Procedure
After lining up with the stack, operate “Squeeze In” to center bales (sometimes it may
be necessary to lightly back into stack to get bales off of the rear spears).
Second, operate “Hoist Up” (which will automatically operate “Squeeze Out”).
Third back up to about 4’-5’ from the stack, (which comes quickly with experience) you
raise the hoist all the way without the bottom bale touching the stack.
Forth, back up tight and let “Stack Down” so bales are on the ground but the tailgate
shaft isn’t powered into the ground (which will drag dirt as you pull away).
Fifth, pull forward about 6 feet and “Stack-Up” then “Lower Hoist” (a micro switch
won’t allow the bale stop to go down until hoist is completely lowered).
Sixth, operate “Bale Stop Down” to allow the top bales to slide into place; (you might
have to accelerate forward to help them slide).
Lastly repeat stacking procedure.
This process may seam long written out like this, but with a little experience it all quickly
becomes a habit that is very fast and easy. You should expect to see average bale capacities
to range from 60-120 bales per hour.
If you seem to be having trouble with some part of it or would like more tips with a particular part of the operation please do not hesitate to call.
DO NOT lower tailgate spears while stacking or while the stack frame is in the raised position, as this will result in damage to your cylinders and/or tailgate spears.
You should NOT need to use the slide off function to have the bales reach the ground when
stacking. If you find it is necessary for your conditions it would be better to have longer
stack letdown cylinders. These longer cylinders are available from Stinger.
January 2005 ——————————————————— Section 3-2
———————————————–——————– STINGER
OPERATION: (Options & Adjustments)
Picking up bales without making the proper adjustments may severely damage the
machine.
For best operation the spears should be level for best operation.
Picking bales up with the spears pointed up may cause the bale to tilt late, slamming
down on the main slide and causing severe damage.
For picking up round bales smaller than 5’ in diameter your settings should be the same as
for 4 x 4 bales.
When changing cylinder stops for handling different size bales make sure you have equal
thickness stops on each cylinder to prevent damage.
When changing cylinder stops for handling different sizes of bales you should only use the
thinner 3/4” stops on the tilt cylinders and use the thicker 1 1/4” stops on the main lift cylinders.
It is recommended that you place a small safety wire on the tilt cylinder stops to prevent
them from being lost in rough field operation.
For information on what adjustments need to be made to handle each size of bale see
pages 3-4 thru. 3-5
January 2005 ——————————————————— Section 3-3

Set-up for handling mid-size
bales (3x3 & 3x4):
1. Install two 3/4” cylinder stops
on each tilt cylinder and remove
all cylinder stops from the main

2. If needed change the number of
spears in tilt assembly.
3. Depending on bale weights you
may need to adjust the proximity switch settings. (See page

OPERATION: (Options & Adjustments continued)
Tilt Control Switch; is intended to control the degree of angle the bale is tilted off the
ground while it is being lifted onto the main slide
assembly.
--The adjustable proximity switch sends a signal to the
main control valve that stops flow of oil to the tilt
cylinders.
--The initial set point for this switch is set so that at
1200-1500 RPM the tilt stops parallel with the lift arm
assembly.
--If you have any trouble with the bales not clearing
the nose cap you should adjust this switch so the tilt
stops sooner.
Lift Arm Deceleration Switch; is intended to slow the speed of the lift arm assembly at the
top end of its stroke and give it a more cushioned stop.
--The adjustable proximity switch sends a signal to the
main control valve that decreases the oil flow to the
main lift cylinders and also puts the tilt cylinders in
“float” position allowing the bale to gently lay onto the
main slide assembly.
--By adjusting this switch you can set how hard and
fast the lift arms come to a stop at the top end of their
stroke.
--To slow the front end sooner, move the switch forward; and to slow the front end later move the switch
backwards.
Adjustments should be made when picking up bales. Bale sizes and weights will effect the
momentum of the bale and how the switches should be set.
January 2005 ——————————————————— Section 3-5
———————————————–——————– STINGER
OPERATION: (Options & Adjustments continued)
Quarter Bale Turner & Letdown; is intended to allow operators to stack bales on the
strings rather than on edge.
The 1/4 Bale Turner can be used on one bale and then turned off for the next. The only
change to be made is the ON-OFF switch in the cab.
The 1/4 Bale Turner should be turned ON or OFF before picking up the bale you want to
make the change on. (Always flip the switch when the front end is in the down position.)
For the location of switches see page 2-6
Hints for using the 1/4 Bale Turn Option
1. The 1/4 bale turner is not supposed to start to turn the bale over until the spears are
completely out of the bale.
2. If you are having trouble turning bales it can be caused by a combination of things.
Some of these things include: bale weight, spear length, density of the bale (square tight
corners). If you are having problems give us a call and we will do what we can to help.
January 2005 ——————————————————— Section 3-6
———————————————–——————– STINGER
OPERATION: (Options & Adjustments continued)
Slide Oiler; is to be used only when you are going to pick up wet bales.
To function the slide oiler press and hold the button on the armrest console for approximately one second. The longer you hold the button the more oil you spray onto the slide.
For the location of switches see page 2-6
Hints for using the Slide Oiler
1. To get started either press the slide oiler button for a second and then slide a few dry
bales to wipe the oil down the rails, or use an oily rag to wipe the rails first.
2. Stinger fills the oiler reservoir with AMOCO Packer Tech Oil which is a food grade
petroleum based oil. If this is not available to you locally you can call and order it direct
from us, just call 1-800-530-5304 DO NOT use vegetable oil (Soybean, Corn,
Canola,…)!!! It will do damage to the paint and be very difficult to remove.
3. Check to see that your spray nozzles are properly pointed and making a uniform pattern
for best operation.

OPERATION: (Options & Adjustments continued)
Stack Retrieval Grapple; (Optional) is intended to be used to assist in retrieving bales.
To retrieve bales:
1. Raise hoist to vertical position.
2. Back into the stack, and when tight against the stack; function “Grapple In”.
3. Lower hoist fully and release grapples from the bales.
To carry a full load of retrieved bales slide first four off and individually load back
over the front with the bale stop in the up position and retrieve second set of bales.
If the grapple is used to assist in stacking or starting a stack:
1. The grapple is to be engaged when the hoist is raised about 60%; and the
bales should be against the stack before the hoist is completely extended
because the hoist extends past 90 degrees.
2. Then operate “Grapple Out” before lowering stack (the micro switch on the
grapple won’t allow you to function the “Stack Down” until the grapple is
disengaged).
For the location of switches see page 2-6
Hints for using the Stack Retrieval Grapple
1. The grapple has a disconnect switch on the armrest console. This switch allows you to
shut off power to the grapple function to help you avoid accidentally engaging the
grapple teeth.
2. If the grapple is engaged into the bales the “Stack Up” & Stack Dn” functions will not
work.
January 2005 ——————————————————— Section 3-8
———————————————–——————– STINGER
FOLLOWING OPERATION:
Refer to Following Operation in the Safety Section of this manual (page 1-6)!!!
The tilt assembly, lift arm assembly, hoist and tailgate assembly should be in their fully
lowered position.
If you leave the tail-gate in the up position or the hoist or lift arms in a partially up position
they may bleed down over a period of time which could cause damage to whatever is under
them.
At the end of the season or before a long period without use, wipe a light coat of oil or Slip
Plate #1 on the top of the rails.
January 2005 ——————————————————— Section 3-9
———————————————–——————– STINGER
MAINTENANCE:
ALL MAINTENANCE PERSONNEL SHOULD READ SAFETY SECTION OF
THIS MANUAL BEFORE WORKING ON THIS MACHINE.
After the first 500 bales, and periodically thereafter, check all bolts and pins for tightness
and wear.
Give special attention to tightness of spear nuts and 1 1/4 x 7 bolts on the tilt & main lift
cylinders.
The slide rails should not be allowed to become heavily rusted or the bales will not slide
well.
At the end of the season or before a long period without use, wipe a light coat of oil or Slip
Plate #1 on the top of the rails.
Light sanding or applying slip plate will help if rust causes bales not to slide.
Proper cooling of your chassis engine is of great importance and should be closely monitored to avoid costly engine failure.
Never let the hydraulic pump run without oil.
With front engine pump, the hydraulic system must have oil any time the engine is running,
even for a few seconds, or damage will occur.
The hydraulic oil installed at the factory is AMOCO 1000 fluid. We recommend oil of this
quality or comparable (J.D. High Guard, Case I.H. Hy-Tran).

TROUBLE SHOOTING AND GENERAL INFORMATION:
Main relief in solenoid control valve is set at 2500 PSI.
Piston Pump is set at 2250 PSI.
At 1200 RPM the tilt and lift movement will take approximately 5-6 seconds for the complete up stroke.
A hydraulic cylinder with an internal leak past the piston will feel noticeably hotter than the
other of a matched set.
If the tilt assembly and lift arm assembly won't hold a bale up in a partially lifted position
without bleeding down, feel for excessive heat on one of the four cylinders after the bale has
been lowered to the ground.
If tailgate is bleeding down during operation, check cylinders for excessive heat with tailgate in the down position.
The tailgate will bleed down over a prolonged period of time (this is natural/expected).
If the “Stack Up” & “Stack Down” functions will not work check to see that the grapples
are fully disengaged and that the grapple micro switch is tripped and connecting the ground
circuit.
(The Grapple Warning Light on the armrest console will be on if the ground circuit
has been disconnected.)
If the “Bale Stop Down” function will not work check to see that the stack frame is down
and that the stack frame micro switch is tripped and connecting the ground circuit.
(The Stack Frame Warning Light on the armrest console will be on if the ground
circuit has been disconnected.)
If the micro switches need adjustment; loosen the arm set screw and adjust arm slightly and
then retighten set screw.
See Wiring Diagram for problems concerning the control valve and check that you are getting 12 volts as specified by wiring diagram.
The wiring & hydraulic diagrams state which coils should be energized with each function
so you will be able to trace the power or oil flow on each respective circuit.
