Electrical Hazard
DANGER
The aerial platform is not electrically insulated.
Death or serious injury can result from contact with,
or inadequate clearance from, an energized
conductor.
Do not go closer than the minimum safe approach
distance as defined by the minimum Safe Approach
Distance as defined by ANSI Standards.
Regard all conductors as energized.
Allow for electrical wire sag and aerial platform sway.
If the work platform, or any part of the aerial platform
contacts a high-voltage electrical conductor, the entire
machine can become electrically charged.
A copy of the Snorkel Limited Warranty is located on the
inside of the back cover of this manual.
If that happens, remain on the machine and do not contact any other structure or object. This includes the
ground, adjacent buildings, poles, and any other objects
that are not part of the aerial platform.
All correspondence relative to this machine, such as
field reports, discrepancy reports, requests for information, etc., should be directed to:
Such contact could make your body a conductor to the
other object, creating an electrical shock hazard resulting in death or serious injury.

LIMITED WARRANTY
Snorkel warrants each new machine manufactured and sold by it to be free from defects in material and workmanship for a
period of one (1) year from date of delivery to a Customer or for one year after the machine has been placed in first service in a
Dealer rental fleet, whichever comes first. Any part or parts which, upon examination by the Snorkel Service Department, are
found to be defective, will be replaced or repaired, at the sole discretion of Snorkel, through its local Authorized Dealer at no
charge.
Snorkel further warrants the structural components; specifically, the mainframe chassis, turntable, booms and scissor arms,
of each new machine manufactured by it to be free from defects in material and workmanship for an additional period of four
(4) years. Any such part or parts which, upon examination by the Snorkel Service Department, are found to be defective will
be replaced or repaired by Snorkel through its local Authorized Dealer at no charge; however, any labor charges incurred as
a result of such replacement or repair will be the responsibility of the Customer or Dealer.
The Snorkel Service Department must be notified within forty-eight (48) hours of any possible warranty situation during the
applicable warranty period. Personnel performing warranty repair or replacement must obtain specific approval by Snorkel

Department within ten (10) days after delivery of the Snorkel product to Customer or Dealer’s rental fleet. Snorkel must be
notified, in writing, within ten (10) days, of any machine sold to a Customer from a Dealer’s rental fleet during the warranty
period.
At the direction of the Snorkel Service Department, any component part(s) of Snorkel products to be replaced or repaired
under this warranty program must be returned freight prepaid to the Snorkel Service Department for inspection. All warranty
replacement parts will be shipped freight prepaid (standard ground) from the Snorkel Service Department or from Snorkel’s
Vendor to Dealer or Customer.

Maintenance and schematics
Maintenance information
The parts drawings located in the repair parts sections,
are designed for use as a guide for proper disassembly
of the machine and components as well as for parts replacement. Always refer to the hydraulic system installation drawings and the electrical wiring diagram before
removing or disassembling associated parts.
CAUTION
Do not attempt to disconnect or remove any hydraulic line before reading and understanding all text
concerning the system hydraulics. In most cases,
disassembly of the machine will be obvious from the
illustration.
When disassembling or reassembling components,
complete the procedural steps in sequence. Do not partially disassemble or assemble one part, then start on
another. Always check your work to assure that nothing
has been overlooked.
The following list is a gentle reminder when disassembling or assembling the machine.
ü Always be conscious of weight.
ü Never attempt to lift heavy objects without the aid of
Parts should be thoroughly inspected before restoring to
service at the time of reassembly. Burrs, nicks or
scratches may be removed from machined surfaces by
honing or polishing with #600 crocus cloth, followed by a
thorough cleaning in an approved cleaning solvent, and
blown dry with compressed air. Do not alter the contour
of any part. If this operation does not restore the part to a
serviceable condition, replace the part. Replace all
O-rings, seals, and gaskets at reassembly. Use new roll
pins or cotter pins. Dip all packing rings and seals in hydraulic oil before reassembling in cylinder and manifold
installations. Replace any part having imperfect threads.
In general, units that have been disassembled can be
reassembled by reversing the order of disassembly.
Remember that the service life of a machine can be increased by keeping dirt and foreign materials out of the
vital components. Precautions have been taken to safeguard against this; shields, covers, seals and filters are
provided to keep air and oil supplies clean; however,
these items must be maintained on a scheduled basis in
order to function properly.
ü Do not allow heavy objects to rest in an unstable
At any time air or oil lines are disconnected, clean surrounding areas as well as the opening and fittings themselves. As soon as a line or component is disconnected,

Maintenance schedules
Snorkel has established a Preventive Maintenance
Schedule that includes Daily Maintenance (Operator's
Inspection), 90 Day or 150 Hour (frequent) Maintenance
and Yearly or 500 Hour (annual) Maintenance, to detect
any defective, damaged or improperly secured parts
and provide information regarding lubrication and other
minor maintenance items.
The Maintenance Schedule following, outlines the requirements of these maintenance checks for each time
interval. The Operator's Daily Maintenance and inspection must be performed by a trained operator. All other
maintenance and inspections must be performed by a
trained service technician only.
Note that the 90 Day or 150 hour (frequent) and yearly or
500 hour (annual) Maintenance, require use of the Preventive Inspection Maintenance Checklist to pinpoint all
inspection items. Retain a copy of these forms for your
records.
They also require that all placards and decals on the unit
are to be inspected.
All placards and decals must be in place and legible. Use
the placards installation drawing and parts listing in the
repair parts section 1 of this manual to check these placards and decals.
Snorkel recommends that you make additional copies of
the Preventive Inspection Maintenance Checklist forms
for your use in performing these inspections.
DANGER
Failure to perform the Preventive Maintenance at
the intervals outlined in the Maintenance Schedule
may result in a unit being operated with a defect that
could result in INJURY or DEATH of the unit operator. Do not allow a unit to be operated that has been
found to be defective.

Lubricants
King pins
Specific lubricants as recommended by Snorkel, should
be used in maintaining your unit. If in doubt regarding the
use of lubricants other than those listed, contact Snorkel
Customer Service Department, St. Joseph Missouri, for
evaluation and recommendation.
King pins (item 1.): Pressure gun lubricate at recommended interval using lubricant as outlined in the maintenance schedule.
Anytime the work platform is elevated to perform maintenance work, properly position the safety prop as outlined on the safety prop decal.
Tie rods (item 2.): Pressure gun lubricate at recommended interval using lubricant as outlined in the maintenance schedule.
DANGER
DO NOT reach through scissors mechanism unless the
safety prop is properly positioned. Injury or death could
occur if the platform is not supported by the safety prop
and should suddenly drop onto personnel performing
maintenance work under the raised platform.
Refer to the above lubrication illustration for location of
item numbers.
Pressure gun application
Service all fittings as indicated in the Maintenance
Schedule and lubrication illustration. Wipe away all excess lubricant from exposed surfaces. Over lubrication
can collect dirt and foreign matter which acts as an abrasive. Lubrication of accessory equipment should be in
accordance with the manufacturer’s recommendations.
4
Tie rods
Steer cylinder ends
Steer cylinder ends (item 3.): Pressure gun lubricate at
recommended interval using lubricant as outlined in the
maintenance schedule.
Wheel bearings
Wheel bearings (item 4.): Clean and repack wheel bearings on non-drive wheels yearly, (or every 500 hours of
operation), using specific lubricants and outlined in the
maintenance schedule.
Clean and repack wheel bearings following normal automotive procedures.
Note:
The wheel bearings used on drive wheels are sealed
bearings and do not require lubrication.
Service information
Batteries
Hydraulic oil reservoir (item 5.): The fluid level should be
kept level with the indicator line of the side of the reservoir and should be checked with all cylinders fully retracted and the platform in stowed position.
Batteries (item 10.): The batteries and battery cables
should be checked to assure that the connections are
tight and free of corrosion. Fluid level should be maintained to assure that the batteries will maintain proper
charge.
The interior of the reservoir should be wiped out and
cleaned each time the hydraulic oil is changed. The reservoir filler/breather cap should be removed and the cap
breather cleaned yearly with Kerosene, Fuel Oil, or
other solvent.
Any time the hydraulic oil is changed or added, it is absolutely necessary that only clean hydraulic oil is used.
Note:
If it becomes necessary to add or use an oil other
than the recommended fluid, it is important that it be
compatible and equivalent to the factory fill. Local oil
suppliers can generally furnish this information.
If questions still remain, contact Snorkel Customer Service Department, St. Joseph, Missouri, for further information.
Return filter
Return filter (item 6.): The hydraulic oil return filter is
mounted in the right hand tray close to the hydraulic oil
reservoir.
Check the batteries specific gravity per the maintenance
schedule.
The batteries are enclosed within a tray located on the
side of the machine. For access to the batteries when
the machine is lowered, position the machine on a hard
level surface, unlatch and open tray.
DANGER
Lead-acid batteries contain sulfuric acid which will damage eyes or skin on contact. When working around batteries, ALWAYS wear a face shield to avoid acid in eyes.
If acid contacts eyes, flush immediately with clear water
and get medical attention.
Wear rubber gloves and protective clothing to keep acid off
skin, if acid contacts skin, wash off immediately with clear
water.
Lead-acid batteries produce flammable and explosive
gases. NEVER allow smoking, flames or sparks around
batteries.
The filter element is a throwaway type filter and should
be changed after the initial break-in period (approximately 50 hours operation time).
The filter condition should be checked at the 90 day or
150 hour Preventive Inspection Maintenance interval or
more frequently under extreme working conditions.
When changing the filter element, the oil inside of the filter element, should be examined for deposits of metal
cuttings, which if present, could indicate excessive wear
in some of the system components.
Door hinges and latches
Door hinges and latches (item 7.): Lubricate at recommended interval using specific lubricants as outlined in
the maintenance schedule.
After lubricating, remove any excess oil or over spray so
it will not collect dirt and debris.
Slide pads
Slide pads (item 8.): Check slide pads for excessive
wear and replace as required. Slide pads do not require
lubrication.
Scissor arm bearings
Scissor arm bearings (item 9.): Scissor arm bearings
are self lubricating. Check bearings for signs of damage
and excessive wear as outlined in the maintenance
schedule. Do not lubricate scissor arm bearings.

Service information
Pothole protection interlock test
Perform this test using the lower controls.
1. Stow the platform and position machine on a
smooth, flat, level concrete slab.
2. Remove all persons and materials from the platform.
3. With the swing-out trays closed, check the ground
clearance under the pothole protector skids (refer
to Figure 1). Clearance should be at least 3-1/4
inch on both sides of the platform.
7. The board will prevent the skid from lowering fully.
Raise the platform while watching the skid. When
the skid contacts the board, the platform should
stop raising and an alarm should sound at less than
six (6) feet platform floor height. The alarm should
then sound when the platform switch is activated.
The platform should not raise any further.
8. Lower the platform, Place the board under the skid
on the left side.
9. Raise the platform while watching the skid. When
the skid contacts the board, the platform should
stop raising and an alarm should sound at less than
six (6) feet platform height. The alarm should then
sound when the platform raise switch is activated.
The platform should not raise any further.
DANGER
The potential for an accident increases when safety
devices do not function properly. Death or serious
injury can result from such accidents. Do not alter,
disable, or override any safety device.
Figure 1–Pothole protector skids
4. Raise the platform wile watching movement of the
skids. The skids should lower to less than one (1)
inch ground clearance when the platform is raised
approximately twelve (12) inches.
5. Fully lower the platform while watching movement
of the skids. The skids should raise to their original
position when the platform is lowered to approximately twelve (12) inches.
6. Place a 1-1/2 inch thick board, such as a 2 x 4, under the skid on the right side (refer to Figure 2).
10. If the platform raise function is not disabled, or the
alarm does not sound, remove the platform from
service until the problem is corrected.
Level sensor interlock test
Perform this test after verifying proper operation of the
pothole protection interlock.
1. Position the platform on a smooth, flat, level surface.
2. Remove all persons and materials from the platform.
3. From the lower controls, raise the platform to access the level sensor at the front of the chassis (refer to Figure 3).
Level Sensor

5. If platform does not stop raising or the alarm does
not sound, remove the machine from service until
the problem is corrected.
DANGER
The potential for an accident increases when safety
devices do not function properly. Death or serious
injury can result from such accidents. Do not alter,
disable, or override any safety device.
Battery care and maintenance
The following information about battery care and maintenance was supplied by Interstate Batteries and is reprinted here with their permission.
1. New batteries need to be cycled several times before reaching full capacity (20-50 cycles, depending on type). Usage should be limited during this
period.
2. Always recharge batteries fully, immediately after
use. Batteries perform best when they are fully
charged. More capacity and longer life will result
from this practice.
3. The deeper the discharge, the fewer number of cycles a lead-acid battery will deliver. Deep discharges deteriorate the battery quicker than lighter
shallow cycles.
4. Battery cables should be intact, and connectors
kept tight at all times. Systematic inspection is recommended.
5. Vent caps should be kept in place and tight during
vehicle operation and battery charging.
6. Batteries should be kept clean -- free of dirt and
corrosion -- at all times. Always keep the top of batteries clean. A film on top of the battery can cause
the current to migrate between the posts, accelerating self discharge.
7. Never let the electrolyte level of a lead-acid battery
fall below the plates. Lack of maintaining the electrolyte in a lead-acid battery causes damage to the
exposed portion of the plate which reduces capacity.
8. Always check electrolyte level before charging. Do
not add water to individual cells unless plates are
exposed. Batteries should be watered after charging unless the plates are exposed before charging.
If exposed before charging, the plates should be
covered by approximately 1/8” of water. Check water level after charging. Water should be kept 1/4”
below the bottom of the fill tube in the cell cover.
9. Water used to replenish batteries should be distilled or treated to not exceed 200 T.D.S. (total dissolved solids... parts per million). Particular care
should be taken to avoid metallic solids (iron).
10. A full charged battery will give you the best and longest service. Be sure the batteries are fully charged
before testing or using. A fully charged battery,
without a drain or load, after the surface charge has
dissipated, is 6.35 volts for a 6 volt battery.
11. Batteries should not be discharged below 20% of ca6.30 volts = 93% charged
6.27 volts = 89% charged
pacity (approximately 1.8 volts per cell under normal
operating load; 1.98 volts open circuit; 1.145 specific
gravity). Proper battery sizing will help avoid excessive discharge.
12. Battery chargers should be sized to fully charge batteries in an eight hour period. Chargers should be
kept in proper operating condition.
13. Do not use a mismatched charger of any type; i.e.,
a 12 volt charger on a 24 volt pack or a 24 volt
charger on a 12 volt pack. An undersized charger
will never get the job done, no matter how long it
tries. An oversized charger will cause excess gassing and heat that could possibly result in a battery
meltdown and/or explosion.
14. Never charge a lead-acid battery with a sealed (gel
cell) battery charger. The lead-acid battery needs
higher voltage to finish its charge. Without it the
battery will never come back to 100% and sulfation
can occur.
15. Always allow batteries to cool off after charging.
The cooling time is very important because heat is
generated during the recharge and discharge cycles. Without the cooling time the heat grows, accelerating grid corrosion which is one of the major
causes of battery failure. Charging practice should
enable batteries to cool before use.
16. Deep cycle batteries need to be equalized periodically. Equalizing is an extended, low current charge
performed after the normal charge cycle. It helps
keep cells in balance. Actively used batteries
should be equalized once per week. Manually
timed chargers should have the charge time extended approximately 3 hours. Automatically controlled chargers should be unplugged and
reconnected after completing a charge cycle.
17. In situations where multiple batteries are connected in series, parallel, or series-parallel, a replacement battery's should be of the same size,
age, and usage level as the companion batteries.
Do not put a new battery in a pack that has 50 or
more cycles. Either replace all the batteries with
new batteries or install a good used battery's in
place of the bad. New batteries should be given a
full charge before use.
7
Service information
18. Periodic battery testing is an important preventative
maintenance procedure. Hydrometer readings of
each cell (fully charged) give and indication of balance
and true charge level.Imbalance could mean the need
for equalizing and is often a sign of improper charging
or a bad cell. Voltage checks (open circuit, charged
and discharged) can locate a bad cell or weak battery.
Load testing will pick out a bad cell when other methods fail. The point is to look for the abnormal. A weak
cell or battery will cause premature failure of companion cells or batteries respectively.
19. As batteries age, their maintenance requirements
change, Generally their specific gravity is higher and
gassing voltage goes up. This means longer charging
time and/or higher finish rate (higher amperage at the
end of charge). Usually, older batteries need to be watered more often and their capacity decreases.
20. “Opportunity charging”, a short partial charge during an
extended duty cycle, is a controversial subject. Generally, the practice is a “crutch” to make up for undersized batteries. The correct approach is to install
adequate battery capacity. If this is impossible because
of lack of space in the battery compartment or extreme
operating conditions (24 hour intermittent use, as an
example), “opportunity charging” is better than excessive battery discharging. However, the practice can
cause batteries to over heat, require more watering,
and usually will shorten battery life. “Opportunity charging” is a trade off; something to avoid if possible. One
charging cycle per day is preferable.
21. Extreme temperatures can substantially affect battery performance and charging. Cold reduces battery capacity and retards charging. Heat increases
water usage and can result in overcharging. Very
high temperature can cause “thermal run away”
which may lead to and explosion or fire. If extreme
temperature is an unavoidable part of an application, consult a battery/charger specialist about
ways to deal with the problem.
Battery charger
SL 20 units are equipped with an onboard automatic
battery charger. This charger has an electronic circuit
that will completely recharge the batteries and automatically turn off after the charge cycle is completed.
The charging cycle may last 1-1/2 to 16 hours depending on the state of charge of the batteries. If the charging
cycle should exceed 16 hours without the batteries being fully recharged, the charger should be shut off and
the batteries should be checked.
If the batteries show no signs of problems and the specific gravity readings are within the range indicated previously, then the charger should be checked.
General charging cautions
1. Do not recharge batteries unless Electrolyte level
has been checked. Operate charger in accordance
with the battery charging instructions outline in this
manual. Place BATTERY DISCONNECT switch in
the “OFF” position before charging batteries.
2. Do not smoke or introduce a flame or spark in the
charging area.
DANGER
Lead acid batteries generate highly explosive Hydrogen gas, especially during charging cycle. To
avoid the possibility of an explosion, charge batteries only in a well ventilated area away form sparks or
flame.
3. Use protective face and eye equipment when
checking the condition of charging batteries.
22. An overly discharged battery might need to be cycled a few times before it can recover fully. If a battery begins to heat before coming up to a full
charge, it might be necessary to discharge the battery and recharge it a few times. The charge and
discharge cycle might help the current acceptance
of the battery and facilitate its recovery to a usable
condition.
23. Inactivity can be harmful to deep cycle batteries. If
they sit for several months, a “boost” charge should
be given -- more frequently in warm climate (about
once a month) than in cold (every 2-3 months).
24. Never store a battery in a discharged state. The sulfate that forms during discharge can make the battery impossible to recharge fully.
