June, 2006
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 dened 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.

trical current ow 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 oor 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
congurations
Before using the aerial platform in any hazardous (clas-
sied) location, make certain it is approved and of the
type required for use in that particular location.
Know and understand the job site trafc-ow patterns
and obey the agmen, road signs, and signals.
While operating the aerial platform, a good safety
practice is to have qualied 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.
ADanger
Pinch points may exist between moving components. Death or serious injury will result from becoming trapped between components, buildings,
structures, or other obstacles. Make sure there is
sufcient clearance around the machine before moving the chassis, booms, or platform. Allow sufcient
room and time to stop movement to avoid contact
with structures or other hazards.
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.
Do not operate the aerial platform if it is damaged or not
functioning properly. Qualied 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 oor grating or otherwise obstruct your view below. Make sure the area below the
platform is free of personnel before lowering.
Keep both feet positioned rmly on the platform oor.
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 rm, at, level
surface capable of withstanding all load forces imposed
by the aerial platform in all operating conditions. Refer to
the General Specications chart for the maximum wheel
load and ground pressure. Raise the booms only when
the aerial platform is on level ground.

ADanger
The aerial platform can tip over if it becomes unstable. Death or serious injury will 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. Do not
raise the boom in winds above 45 km/h (28 mph).
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, ags, 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.
Take care to prevent rope, electrical cords and hoses,
etc., from becoming caught in or on the aerial platform.
If the platform or booms becomes caught on an adjacent structure or other obstacle and is prevented from
normal 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
ame, sparks or other hazards that might cause re or
explosion.
Do not operate any of the aerial platform functions while
the battery charger is plugged in.
AWarning
Batteries give off hydrogen and oxygen that can
combine explosively. Death or serious injury could
result from a chemical explosion. Do not smoke or
permit open ames or sparks when checking the
batteries.
Battery acid can damage the skin and eyes. Serious
infection or reaction can result if medical treatment
is not given immediately. Wear face and eye protection when working near the batteries.
Batteries contain sulfuric acid that can damage your eyes
or skin on contact. Wear a face shield, rubber gloves,
and protective clothing when working around batteries.
If acid contacts your eyes, ush immediately with clear
water and get medical attention. If acid contacts your
skin, wash off immediately with clear water.
Hydraulic System
The hydraulic system contains hoses with hydraulic uid
under pressure.
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.
Do not operate the aerial platform from trucks, trail-
ers, railway cars, oating vessels, scaffolds or similar
equipment unless the application is approved in writing
by Snorkel.
Do not use the aerial platform as a crane, hoist, jack or
for any purpose other than to position personnel, tools
and materials.
Do not climb on the guardrails or use ladders, planks or
other devices to extend or increase the work position
from the platform.
TB60/66J – 0084030EE 13
Hydraulic uid escaping under pressure can have
enough force to inject uid into the esh. Serious
infection or reaction will result if medical treatment
is not given immediately. In case of injury by escap-
ing hydraulic uid, seek medical attention at once.
Do not place your hand or any part of your body in front
of escaping hydraulic uid. Use a piece of cardboard or
wood to search for hydraulic leaks.
Engine and Fuel Handling Precautions
Refer to the engine manufacturer’s Operator’s Manual
for complete information on safe engine operation,
maintenance and specications.

Engine exhaust contains carbon monoxide, a poi-
sonous gas that is invisible and odorless. Breathing
engine exhaust fumes will cause death or serious
illness. Do not run the engine in an enclosed area
or indoors without adequate ventilation.
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 ames while fueling or
near fueling operations.
Never remove the fuel cap or ll the fuel tank while the
engine is running or hot. Never allow fuel to spill on hot
machine components.
Maintain control of the fuel ller nozzle when lling the
tank. Spilled fuel is a potential re hazard.
Do not overll the fuel tank. Allow room for expansion.
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.
ACaution
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.
