.

CAUTION

means one of two things: (1) an action, about to
be performed, is potentially hazardous and might
result in minor personal injury if not done
correctly, or (2) an action, about to be performed,
can harm the SR if not done correctly.

QUALIFIED OPERATORS

T

SR aerial platforms have built-in safety features
and have been factory tested for compliance with
Snorkel specifications and industry standards.
However, any personnel-lifting device can be
potentially dangerous in the hands of untrained
or careless operators.

Training is essential and must be performed by a
QUALIFIED person. Become proficient in
knowledge and actual operation before using the
SR on the job. You must be trained and
authorized to perform any functions of the SR.
Operation of the SR must be within the scope of
the machine specifications.

Before operating an SR you must read and
understand the operating instructions in this
manual as well as the decals, warnings, and
instructions on the machine itself.

Before operating an SR you must be
AUTHORIZED by the person in charge to do
so.

The following rules will help ensure the
safety of personnel and help prevent

needless downtime because of damaged
equipment.

1. Only TRAINED and AUTHORIZED operators
shall be permitted to operate the equipment.

2. All manufacturer’s operating instructions and
safety rules and all employers’ safety rules and
all OSHA and other government safety rules
must be strictly adhered to.

3. Repairs and adjustments shall be made only
by QUALIFIED TRAINED maintenance
personnel.

4. No modification shall be made to the
equipment without prior written consent of the
Snorkel Engineering Department.

5. You must make a prestart inspection of the SR
at the beginning of each shift. A malfunctioning
machine must not be used.

6. You must make an inspection of the work
place to locate possible hazards before operating
an SR.

DANGER

Misuse of this machine can result in DEATH
or SERIOUS INJURY.

Do not operate this equipment unless you are
TRAINED and AUTHORIZED and have read
and thoroughly understand all information
given in this Operator’s Manual and on all
DANGER and CAUTION signs on the

SAFE OPERATION

T

The following safety information is vitally
important for safe operation of an SR. Failure to
follow these instructions can result in personal
injury or DEATH.



Pre-start Inspection

Prior to each shift, the SR shall be given a visual
inspection and function test. (See the “DAILY
INSPECTION & MAINTENANCE” chapter in this
manual for a list of items to inspect and test.)

Do not operate an SR unless you are trained and
authorized, understand the operating
characteristics of the SR, and have inspected
and tested all functions to be sure they are in
proper working order. (See the “DAILY
INSPECTION & MAINTENANCE” chapter.)



Work Place Inspection and Practices



Do not use an SR as a ground for welding.
Ground to the work piece.

Before an SR is used, and during use, check the
area in which it is to be used for possible hazards
such as, but not limited to:

drop-offs or holes,

•

side slopes,

•

bumps and floor obstructions,

•

debris,

•

overhead obstructions and electrical

•

conductors,

hazardous locations,

•

inadequate surface and support to withstand

•

all load forces imposed by the aerial platform
in all operating configurations,

wind and weather conditions,

•

presence of unauthorized persons,

•

other possible unsafe conditions.

•

Before using the aerial platform in any hazardous
(classified) location, make certain it is approved
and of the type required by ANSI/NFPA 505 for
use in that particular location.

A recommended safety practice is to have
ground personnel, who are trained in the
operation of SR emergency controls, working in
the immediate vicinity of an elevated SR. In the
event of an emergency, they can assist the
platform operator.

1. SAFETY

1. SAFETY

1. SAFETY

When moving the platform, check the clearance
around the SR to avoid contact with structures or
other hazards. Always look in the direction of
motion.

Keep ground personnel from under the platform
when the platform is raised.

Secure all accessories, containers, tools, and
other materials in the platform to prevent them
from accidentally falling or being kicked off the
platform.

Do not engage in any form of “horseplay” or
“stunt driving” while operating an SR.

Do not permit riders on the machine anyplace
other than on the platform.

Remove all loose objects stored in or on the
machine, particularly in the platform. Remove all
objects which do not belong in or on the
machine.

When other moving equipment is in the area,
take special precautions to comply with local
regulations regarding warnings.

Never steady the platform by positioning it
against another platform.

Do not operate an SR that is not functioning
properly, or has been damaged, until the
machine has been repaired by a qualified
maintenance person.

Do not operate an SR that does not have all its
decals and placards attached and legible.

Drive the machine with care and at speeds
compatible with conditions. Use extra caution
when driving over rough ground, on slopes, and
when turning.

Know and understand the job site traffic-flow
patterns and obey the flagmen, road signs, and
signals.

Watch for bystanders and never allow anyone to
be under, or to reach through, the machine and
its equipment while operating.



Electrocution

SR’s are all-metal, NON-INSULATED, aerial
work-platforms. Do not operate an SR near
ELECTRICAL conductors. Regard all conductors
as being energized.

Do not operate outside during a thunderstorm.

platform before attempts are made to free the
platform using ground controls.

Do not exceed the platform capacity nor the
platform-extension capacity shown on the
capacity placards located at the entrance to the
platform and on the toeboard of the platform
extension.



Tipover & Falling Hazards

On scissor lifts, like the SR, personal fall
protection is not required by ANSI, Federal
OSHA, nor Snorkel. However, fall restraint might
be required by work regulations. If so, the user is
responsible for fitness and method of use.

The guardrail system is your fall protection. Make
sure the guardrail system is properly installed
and that all gates and fasteners are in place.

It is best not to transfer from the platform to
another structure or from the structure to the
platform, unless that is the safest way to do the
job. Judge each situation separately taking the
work environment into account. If it is necessary
to transfer from the platform to another structure
the following guidelines apply:

Where possible, place the work platform

•

next to a roof or walking structure to do
the transfer.

Transfer your anchorage from one

•

structure to another before you step
across.

Remember that you might be transferring

•

to a structure where

personal fall arrest

is required.

Do not raise the platform if the SR is on soft
ground. Raise the platform only on a firm surface
capable of withstanding all load forces imposed
by the aerial platform in all operating conditions.

Do not allow wires, cables, hoses, rope, or other
materials to trail down from the platform or be
entangled in the platform.

If you have to level an SR, that does not have
outriggers, be sure the shoring you use is strong
enough to support the weight of the SR and that
the SR wheels are chocked so that the SR
cannot be driven.

Do not jerk the controls. Move the controls slowly
and deliberately to avoid jerky and erratic
operation. Always stop the controls in the neutral,
off, position before going in the opposite
direction.

Do not use the platform for any purpose other
than to position personnel, their tools and
materials.

Do not use an SR as a crane, hoist, or jack.

Do not operate an SR in winds, or wind gusts, of
28 mph (12.5 m/s) or more.

Do not add anything to an SR that will increase
the wind loading (billboards, banners, flags, etc.).

Use the platform entrance, do not climb

•

over the guard rails.

Maintain a firm footing on the platform floor.
Climbing on the guardrails is prohibited.

Do not use ladders, planks, or other devices to
extend or increase your work position from the
platform.

Do not operate an SR from a position on trucks,
trailers, railway cars, floating vessels, scaffolds,
or similar equipment unless the application is
approved in writing by Snorkel.

If the platform or elevating assembly becomes
caught, snagged, or otherwise prevented from
normal motion by an adjacent structure, or other
obstacles, such that control reversal does not
free the platform, remove all personnel from the

Crushing

Always look in the direction of travel. Avoid
overhead obstructions.

Make sure the area below the platform is free of
personnel before lowering.

P/N 569300

GENERAL SAFETY PRECAUTIONS

T

Personnel Precautions



If you encounter any suspected malfunction of
the aerial platform, or any hazard or potentially
unsafe condition relating to capacity, intended
use, or safe operation, cease operation and seek
assistance from management.

Operator General Precautions



Make sure that all protective guards, cowlings,
and doors are in place and secure.

Mounting & Dismounting Precautions



Use three points of support when getting on or
off the platform. Keep the platform clean.

Do not jump off the machine.

Do not dismount while the machine is in motion.

1. SAFETY

Do not attempt repairs unless you are trained.
Refer to manuals and experienced repair
personnel for help.

Charge batteries in a well-ventilated area free of
flame, sparks, or other hazards that might cause
fire or explosion.

Use extreme caution when removing radiator
caps. Park the machine and let it cool down
before opening a pressurized compartment.

Fuel Handling Precautions



Do not smoke or permit open flames while
fueling or near fueling operations.

Maintain control of the fuel filler nozzle when
filling the tank.

Do not fill the fuel tank to capacity. Allow room
for expansion.

Starting and Stopping Precautions



Do not start until all personnel are clearly away
from the machine.

Before leaving the operator’s station, place the
machine in the stowed position.

Remove the starter key from the
set the
the machine parked or unattended.



Do not modify an SR in any way.

Do not override any of the safety features of an
SR.

Do not exceed the side-pull forces listed on the
capacity placards located at the entrance to the
platform and on the toeboard of the platform
extension.

Limit travel speeds according to conditions. Take
into account: grade, surface, congestion,
visibility, side slope, location of personnel, and
other hazards.



Do not use your hand to search for hydraulic oil
leaks. High pressure hydraulic oil can easily cut
and penetrate your skin — a very serious injury
that requires immediate attention by a medical
specialist trained in that type of injury. Use a
piece of cardboard or wood to search for
hydraulic oil leaks.

proper venting may result in pressurization of the
tank.

Never use fuel for cleaning purposes.

For diesel engines, use the correct fuel grade for
the operating season.

SAFETY DECALS & PLACARDS

T

There are several safety decals and placards on
an SR. Their locations and descriptions are
shown in this section. Take time to study them.

Be sure that all the safety decals and placards
on the SR are legible. Clean or replace them if
you cannot read the words or see the pictures.
Clean with soap & water and a soft cloth. Do not
use solvents.

You must replace a decal or placard if it is
damaged, missing, or cannot be read. If it is on a
part that is replaced, make sure a new decal or
placard is installed on the replaced part. See
your Snorkel dealer for new decals and placards.

Refer to the PLACARDS AND DECALS

Level Sensor

The level sensor alarm warns the SR operator
that the SR is not level. If the tilt continues to
increase, the SR will eventually tip over. When
you hear this alarm, immediately lower the
platform completely down. When the platform is
completely down, determine and correct the
cause of the tilt before raising the platform again.

NOTE: While the alarm is sounding it is not
possible to drive the SR nor raise the
platform.

FLASHING LIGHT

T

The flashing light alerts people that the SR is
present and that the SR is moving. The light
flashes at about one flash per second any time
the SR engine is running. There is no ON/OFF
switch for the flashing light, it cannot be turned
off while the SR is running.

LANYARD ANCHOR POINTS

T

There are four anchors on the floor of the
platform, one at the front of the roll-out deck, one
at the back of the platform, and one on each side
of the platform.

NOTE: These anchors are not for lifting or
tying down the machine.

You should attach your fall protection to the
anchors if work rules require it.

AIR FILTER

The air filter gauge is located between the air
filter and the intake manifold. The gauge
measures the vacuum (air pressure) between the
intake manifold and the air filter. As the filter
clogs, the vacuum increases (pressure drops).
As the vacuum increases, a red indicator raises
toward the clear area of the gauge. When you
can see the indicator in the clear area of the
gauge, it’s time to change the air filter.

The indicator stays at its highest setting, it does
not go to the bottom of the gauge when the
engine is turned off or the filter changed. After
the filter is changed, press the small reset button
to reset the indicator to the bottom of the gauge.

7. OPERATION

7. OPERATION

This chapter explains how to start and run an SR
that has either a gasoline or diesel engine.
Starting a gasoline engine that is set up to burn
LP-only or dual-fuel is also discussed in this
chapter.

To use this chapter, first decide whether you will
be starting and operating the SR from the base­control panel or the platform-control box. Go to
the section entitled “OPERATING FROM THE
BASE-CONTROL BOX” if you intend to start and
run the SR from the base-control panel. Go to
“OPERATING FROM THE PLATFORM­CONTROL BOX” if you intend to start and run
the SR from the platform.

After you have made the “base-control / platform­control” decision you need to know whether the
SR has a gasoline or diesel engine. If it has a
“gasoline” engine you further need to know
whether it is set up to burn LP-only, or dual-fuel
(LP or gasoline). If it is set up to burn dual-fuel
you have to decide whether to burn gasoline or
LP. The simplest way to tell what kind of engine
set up you have is to look in the fuel
compartment on the left side of the SR -- open
both fuel compartment doors.

the following:

1. Set the

BATTERY

switch (1) to ON.

1. If the only fuel source you see there is a
tank labeled GASOLINE FUEL, the SR has a
gasoline engine set up to burn gasoline.

2. If the only fuel source you see is a tank
labeled DIESEL FUEL, the SR has a diesel
engine.

3. If the only fuel source you see is one or
more LP tanks, the SR has a special gasoline
engine set up to burn LP-only.

4. If you see a GASOLINE FUEL tank and
one or more LP tanks, the SR has a special
gasoline engine set up to burn either gasoline
or LP.

Once you have determined the type of engine
installed and the type of fuel you will burn you
should go to the corresponding subsection that
explains how to start that type engine. Read the

5. Engine coolant

The Kubota engine is liquid cooled. At operating
temperatures the coolant should be at the HOT
level (1). When cold there should be
approximately 1 inch (2.5 cm) of coolant in the
bottom of the reservoir.

The coolant is half water and half ethylene glycol.

Visually inspect the entire length of the fuel line,
from the engine to the fuel tank, for leaks.

4. Engine oil

To add coolant:

Remove the cap (2) from the coolant
reservoir.

Add coolant and replace cap.

6. Radiator cap

Keep the oil level between the marks on the
dipstick (1).

The distance between the top and bottom
dipstick marks corresponds to about 1 qt. (one
liter). Add oil, if needed at the cap (2) on top of
the engine.

NOTE: See the “SPECIFICATIONS” chapter
for the correct engine oil grade and weight.

10. Battery terminals

Battery terminals should be clean and free of
corrosion.

11. Hydraulic tank cap

10. DAILY INSPECTION & MAINTENANCE

13. Hydraulic oil leaks

DANGER

Leaking hydraulic oil can cause burns, fires,
falls (slipping), cuts, and puncture wounds (if
under high pressure). Do not tolerate
hydraulic oil leaks. They are dangerous.

Hydraulic oil leaks are easily visible and can
show up anyplace. Visually inspect the entire
machine for hydraulic oil. Check the ground
under the machine for leaked oil.

Check to see that the cap is in place and is tight.

12. Hydraulic oil level

To check the hydraulic oil level:

Completely lower the platform.

The hydraulic oil level should be at the full
level.

If necessary, add hydraulic oil at the Hydraulic oil
tank cap. See the “SPECIFICATIONS” chapter
for type and grade of hydraulic oil.

Check for loose fittings at the valve.

Pay particular attention to the cylinders, check to
see that there is no oil leaking from the seal, also
check all hoses that run to the cylinders.

P/N 569300

10. DAILY INSPECTION & MAINTENANCE

14. Tires and wheels

SR tires are foam filled. Punctures of the type
caused by bolts, screws, or nails are not a
problem. Look for large holes or long cuts
completely through the tire body: holes or cuts
where foam is being forced or eroded out of the
tire. Also look for large imbedded objects, such
as angle iron, that can rip a tire body open under
some conditions.

(OPTION-BIG PAW Tires)

15. Bolts and fasteners

Visually inspect all fasteners to see that none are
missing or obviously loose.

DANGER

Death or serious injury can result if an SR
tips over. An air-filled tire that has an air leak
or blow-out is a tip over hazard. Do not raise
the SR platform if any tire has an air leak or is
in such condition that a blow-out could
occur.

Some Big Paw tires are air-filled. Air-filled tires
should be visually checked several times a day
to see that they are properly inflated. Air-filled
tires should be checked very carefully for
imbedded material, cuts, punctures, or abraded
areas. Do not tolerate a suspect tire, it can be
fatal.

Pay particular attention to all of the wheel nuts.
None should be visibly loose, missing, or
deformed.

16. Structural damage & welds

10. DAILY INSPECTION & MAINTENANCE

19. Bubble level

Visually check to see that the bubble level is not
damaged, that it is full of fluid, that the bubble
does not exceed the diameter of the center black
circle, and the surface on which the bubble level
is mounted is not deformed or bent out of level.

20. Guides, rollers, and slides

(machines with outriggers)

Visibly inspect all welds for cracks, all structural
members for deformity, and all sheet metal for
dents that could interfere with machine
operation.

17. Guardrails

Pay particular attention to the guardrails. Make
sure the guardrails are properly installed, that all
the fasteners are in place, and that the safety
chain or swinging gate is in place and works
properly.

18. Lanyard anchorages

(option)

GFCI OUTLET

The GFCI (ground fault circuit interrupt) is
located under the platform-control box. To use
the outlet the SR must have the AC
GENERATOR option or you must plug the
power cord, at the base-control panel, into a
source of power. Set the

The GFCI will protect against short circuits to
ground. When there is a short to ground the
GFCI will shut off power to the outlet.

To reset the outlet:

Unplug the equipment being used.
Press the reset button on the GFCI outlet.

This should restore power to the outlet. If it

The outrigger controls are on the upper left side

The outriggers are used to level the SR (for
complete outrigger operating procedures see
the “OPERATION” chapter).

NOTE: The SR must be on a firm surface
capable of withstanding all load forces
imposed by the aerial platform in all
operation conditions before the outriggers
are used.

P/N 569300

T

BIG PAW TIRES

Because Big Paw tires are wider than standard
tires, Big Paw tires decrease the pressure the
SR exerts on the ground and give more traction
than standard tires. Therefore, Big Paw

12 - 1

12. OPTIONS

tires are better suited for sandy soil than
standard tires. Big Paws increase the overall
width of the SR.

DANGER

Death or serious injury can result if an SR
tips over. An air-filled tire that has an air
leak or blow-out is a tipover hazard. Do not
raise the SR platform if any tire has an air
leak or is in such condition that a blow-out
could occur.

ELECTRICAL OUTLET

T

Some Big Paw tires are air-filled. Air-filled tires
should be visually checked several times a day
to see that they are properly inflated. Air-filled
tires should be checked very carefully for
imbedded material, cuts, punctures, or abraded
areas. Do not tolerate a suspect tire, it can be
fatal.

NOTE: “Big Paw” is a generic name, it is not
molded into the tire sidewall.

FLASHING LIGHT

T

The electrical outlet on the platform, and its
power cable, are designed to supply 2 kW of
continuous duty power to run power tools of
various sorts. The power can come from either
the optional ac generator, discussed elsewhere
in this chapter, or from an electrical source
outside the SR. If you use an electrical source
outside the SR be sure you disconnect it before
you drive the SR away.

SWINGING GATE

T

The flashing light alerts people that the SR is
present and that the SR is moving. The light
flashes at about one flash per second any time
the SR is running. There is no ON/OFF switch
for the flashing light, it cannot be turned off
while the SR is running.

12 - 2

The swinging gate is designed to automatically
close after you enter or leave the platform. It
helps prevent people from falling off the
platform.

P/N 569300

12. OPTIONS

SPARK ARRESTOR

T

The spark arrestor prevents incandescent
carbon particles from coming out the tail pipe.
Baffles in the spark arrestor slow the flow of
particles through the exhaust system. The
additional time spent in the exhaust system lets
the carbon completely burn before it comes out
the tail pipe.

LANYARD ANCHOR POINTS

T

There are four anchors on the floor of the
platform, one at the front of the roll-out deck,
one at the back of the platform, and one on
each side of the platform.

NOTE: These anchors are not for lifting or
tying down the machine.

AC GENERATOR

T

CAUTION

Do not use the ac generator unless the
hydraulic oil is over 70°F (21°C). The output
voltage of the generator depends on the
temperature of the hydraulic oil. Temperature
below 70°F (21°C) will cause dangerously low
output voltages that can burn out some kinds of
electrical equipment.

The hydraulically powered, 115 V ac generator
can be used anytime the SR engine is running
and the SR is completely stationary. Turning
the ac generator on stops all machine
movement.

Set the
control box, to on (--) and a total of 2 kW,
continuous duty, 120 V ac power is available
from the two electrical outlets under the
platform-control box or the electrical outlet on
the end of the generator housing.

NOTE: To energize the two platform
electrical outlets, the power cord from the
platform outlets must be plugged into the

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 Service Department prior to performing any warranty repair or
replacement.

Customer and Dealer shall not be entitled to the benefits of this warranty and Snorkel shall have no obligations
hereunder unless the "Pre-Delivery and Inspection Report" has been properly completed and returned to the
Snorkel Service 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.

REPLACEMENT PARTS WARRANTY

Any replacement or service part made or sold by Snorkel is not subject to the preceding
beyond the normal warranty period of the machine upon which the part was installed.

THIS WARRANTY EXCLUDES AND SNORKEL DOES NOT WARRANT:

1. Engines, motors, tires and batteries which are manufactured by suppliers to Snorkel, who furnish their

own warranty. Snorkel will, however, to the extent permitted, pass through any such warranty protection
to the Customer or Dealer.

2. Any Snorkel product which has been modified or altered outside Snorkel's factory without Snorkel's

written approval, if such modification or alteration, in the sole judgment of Snorkel's Engineering and/or
Service Departments, adversely affects the stability, reliability or service life of the Snorkel product or
any component thereof.

3. Any Snorkel product which has been subject to misuse, improper maintenance or accident. "Misuse"

includes but is not limited to operation beyond the factory-rated load capacity and speeds. "Improper
maintenance" includes but is not limited to failure to follow the recommendations contained in the
Snorkel Operation, Maintenance, Repair Parts Manuals. Snorkel is not responsible for normal
maintenance, service adjustments and replacements, including but not limited to hydraulic fluid, filters and
lubrication.

4. Normal wear of any Snorkel component part(s). Normal wear of component parts may vary with the

type application or type of environment in which the machine may be used; such as, but not limited to
sandblasting applications.

5. Any Snorkel product that has come in direct contact with any chemical or abrasive material.

6. Incidental or consequential expenses, losses, or damages related to any part or equipment failure,

including but not limited to freight cost to transport the machine to a repair facility, downtime of the
machine, lost time for workers, lost orders, lost rental revenue, lost profits or increased cost.

This warranty is expressly in lieu of all other warranties, representations or liabilities of Snorkel, either
expressed or implied, unless otherwise amended in writing by Snorkel's President, Vice
President-Engineering, Vice President-Sales or Vice President-Marketing.

SNORKEL MAKES NO WARRANTIES WHICH EXTEND BEYOND THE DESCRIPTION OF THIS LIMITED
WARRANTY. SNORKEL MAKES NO IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A
PARTICULAR PURPOSE AND DISCLAIMS ALL LIABILITY FOR INCIDENTAL OR CONSEQUENTIAL
DAMAGES, INCLUDING BUT NOT LIMITED TO INJURY TO PERSONS OR PROPERTY.

The Customer shall make all warranty claims through its local Authorized Dealer and should contact the
Dealer from whom the Snorkel product was purchased for warranty service. Or, if unable to contact the Dealer,
contact the Snorkel Service Department for further assistance.
