OPERATOR’S
MANUAL
Part Number 0420453
March 2014
The aerial platform is not electrically insulated. Death or serious injury will 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 section in Chapter 3–Safety.
Regard all conductors as energized.
Allow for electrical wire sag and aerial platform sway.
If the platform, booms, or any part of the aerial platform contacts a high-voltage electrical conductor,
the entire machine can become electrically charged.
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.
Such contact could make your body a conductor to the other object, creating an electrical shock hazard
resulting in death or serious injury.
If an aerial platform is in contact with an energized conductor the platform operator must warn ground
personnel in the vicinity to stay away. Their bodies can conduct electricity creating an electrical shock
hazard resulting in death or serious injury.
Do not approach or leave the aerial platform until the electricity has been turned off.
Do not attempt to operate the lower controls when the platform, booms, or any part of the aerial platform is in contact with a high-voltage electrical conductor or if there is an immediate danger of such
contact.
Personnel on or near an aerial platform must be continuously aware of electrical hazards, recognizing
that death or serious injury can result from contact with an energized conductor.

Safety devices reduce the likelihood of an accident. Never
disable, modify, or ignore any safety device. Safety alerts
in this manual indicate situations where accidents may
occur.
If any malfunction, hazard or potentially unsafe condition relating to capacity, intended use, or safe operation
is suspected, stop aerial platform operation and seek
assistance.
The operator bears ultimate responsibility for following
all manufacturer’s instructions and warnings, regulations
and safety rules of their employer and/or any state or
federal law.
Electrocution Hazards
The aerial platform is made of metal components and is
not insulated. Regard all conductors as energized. Do
not operate outside during a thunderstorm.
Minimum Safe Approach Distance
Minimum safe approach distances to energized power
lines and their associated parts must be observed while
operating the aerial platform.
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 ANSI.
ANSI publications define minimum distances that must
be observed when working near bus bars and energized
power lines. Table 1 and Figure 3 are reprinted courtesy
of Scaffold Industry Association, ANSI/SIA A92.5.

Chapter 3 – Safety
Prestart Inspection
Perform a prestart inspection before each shift as described in Chapter 7. Do not use the aerial platform on
the job unless you are trained and authorized to do so.
Work Place Inspection and Practices
Do not use the aerial platform as a ground connection
when welding. The welding ground clamp must be attached to the same structure that is being welded. Electrical current flow can be very intense, causing serious
internal damage to some components.
Inspect the area before and during aerial platform use.
The following are some potential hazards that may be in
the work place.
• Debris
• Slopes
• Drop-offs or holes
• Bumps and floor obstructions
• Overhead obstructions
• Unauthorized persons
• High voltage conductors
• Wind and weather conditions
• Inadequate surface and support to withstand load
forces applied by the aerial platform in all operating
configurations
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.
Know and understand the job site traffic-flow patterns and
obey the flagmen, road signs, and signals.
Always look in the direction of movement. Drive with care
and at speeds compatible with the work place conditions.
Use caution when driving over rough ground, on slopes,
and when turning. Do not engage in any form of horseplay
or permit riders any place other than in the platform.
Secure all accessories, containers, tools, and other materials in the platform to prevent them from accidentally
falling or being kicked off the platform. Remove all objects
that do not belong in or on the aerial platform.
Never steady the platform by positioning it against another platform.
Warning
The potential for an accident increases when operating an aerial platform that is damaged or malfunctioning. Death or serious injury can result from such
accidents. Do not operate the aerial platform if it is
damaged or malfunctioning.
Do not operate the aerial platform if it is damaged or not
functioning properly. Qualified maintenance personnel
must correct the problem before putting the aerial platform
back into service.
Operation
Use three points of support when entering or exiting the
platform. For example, use two hands and one foot when
climbing into the platform.
Never cover the platform floor grating or otherwise obstruct your view below. Make sure the area below the
platform is free of personnel before lowering.
While operating the aerial platform, a good safety practice is to have qualified personnel in the immediate work
area to:
• Help in case of an emergency
• Operate emergency controls as required
• Watch for loss of control by platform operator
• Warn the operator of any obstructions or hazards that
may not be obvious to them
• Watch for soft terrain, sloping surfaces, drop-offs, etc.
where stability could be jeopardized
• Watch for bystanders and never allow anyone to be
under, or to reach through the booms while operating
the aerial platform
Danger
Pinch points may exist between moving components.
Death or serious injury can result from becoming
trapped between components, buildings, structures,
or other obstacles. Make sure there is sufficient clearance around the machine before moving the chassis,
booms, or platform. Allow sufficient room and time
to stop movement to avoid contact with structures
or other hazards.
Keep both feet positioned firmly on the platform floor.
Operate the controls slowly and deliberately to avoid jerky
and erratic operation. Always stop the controls in neutral
before going in the opposite direction.
Do not dismount while the aerial platform is in motion or
jump off the platform.
Properly stow the aerial platform and secure it against
unauthorized operation at the end of each work day,
before transporting, or if it is left unattended.
Tip-Over and Falling Hazards
Operate the aerial platform only on a firm, flat, level surface capable of withstanding all load forces imposed by
the aerial platform in all operating conditions. Refer to
the General Specifications chart for the maximum wheel
load and ground pressure. Raise the booms only when
the aerial platform is on level ground.
12 AB80J/AB85J – 0420453
Chapter 3 – Safety
Danger
The aerial platform can tip over if it becomes unstable.
Death or serious injury can result from a tip-over accident. Do not drive or position the aerial platform for
elevated use near any drop-off, hole, slope, soft or
uneven ground, or other tip-over hazard.
All platform occupants must wear a fall restraint device
connected to a lanyard anchor point.
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:
1. Where possible, place the platform over a roof or
walking structure to do the transfer.
2. Transfer your anchorage from one structure to the
other before stepping across.
3. Remember that you might be transferring to a structure where personal fall arrest is required.
4. Use the platform entrance, do not climb over or
through the guardrails.
Do not operate the aerial platform in windy or gusty conditions. Do not add anything to the aerial platform that will
increase the wind loading such as billboards, banners,
flags, etc.
Never operate the aerial platform without all parts of the
guardrail system in place and the gate closed. Make
sure that all protective guards, cowlings, and doors are
securely fastened.
Do not exceed the platform capacity as indicated on the
platform rating placard on the platform. Do not carry loads
that extend beyond the platform guardrails without prior
written consent from Snorkel.
motion, reverse the control to free the platform. If control
reversal does not free the platform, evacuate the platform
before attempting to free it.
Electrical System
Charge the batteries in a well-ventilated area free of
flame, sparks, or other hazards that might cause fire or
explosion.

Engine and Fuel Handling Precautions
Refer to the engine manufacturer’s Operator’s Manual for
complete information on safe engine operation, maintenance, and specifications.
Danger
Engine exhaust contains carbon monoxide, a poisonous gas that is invisible and odorless. Breathing
engine exhaust fumes can cause death or serious
illness. Do not run the engine in an enclosed area or
indoors without adequate ventilation.
Chapter 3 – Safety
Operate dual fuel machines on LPG fuel when indoors to
reduce exhaust fumes and carbon monoxide.
Be careful not to run the diesel fuel tank empty. Bleed the
fuel system if air enters the lines between the tank and
the injection pump.
Allow the engine to return to idle before shutting the
engine off.
Do not smoke or permit open flames while fueling or near
fueling operations.
Never remove the fuel cap or fill the fuel tank while the
engine is running or hot. Never allow fuel to spill on hot
machine components.
Maintain control of the fuel filler nozzle when filling the
tank. Spilled fuel is a potential fire hazard.
Do not overfill the fuel tank. Allow room for expansion.
Clean up spilled fuel immediately.
Tighten the fuel tank cap securely. If the fuel cap is lost,
replace it with an approved cap from Snorkel. Use of a
non-approved cap without 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.
Caution
Engine coolant escaping under pressure can cause
serious burns. Shut the engine off and let it cool
before removing the radiator cap.
Let the engine and radiator cool before adding coolant.

If the oil in a Deutz engine exceeds 230°F (110°C) an
alarm will sound and the engine will shut off. Any time
there is no alternator current being produced, an alarm
will sound and the engine will shut off. This prevents high
engine temperature if the fan belt breaks.
Do not restart the engine until the condition that caused
the overheating has been corrected.
Low Oil Pressure Alarm
The low oil pressure alarm sounds when the engine oil
pressure is near the lower limit for safe engine operation.
If the alarm sounds, lower the platform to the ground and
then turn the engine off. Do not restart the engine until
the condition that caused the low oil pressure has been
corrected.
If the engine oil pressure falls below a safe operating value
the engine will shut off. The engine can be restarted with
low oil pressure, but it will only run a few seconds before
it shuts off again.
