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.
Danger
The aerial platform can tip over if it becomes unsta-
ble. 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.
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 struc-
ture 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.
Do not operate the aerial platform from trucks, trail-
ers, railway cars, floating 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.
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 ad-
jacent 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, evacu-
ate 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.
Do not operate any of the aerial platform functions while
the battery charger is plugged in.
Warning
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 flames 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 protec-
tion 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, flush 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 fluid
under pressure.
Danger
Hydraulic fluid escaping under pressure can have
enough force to inject fluid into the flesh. Serious
infection or reaction will result if medical treatment
is not given immediately. In case of injury by escap-
ing hydraulic fluid, seek medical attention at once.
