the machine to a firm,
level surface. If the tilt
alarm sounds when the
platform is raised, use
extreme caution to lower
the platform.
Do not alter or disable the limit switches.
Do not drive over 1.1 kmh with platform raised.

Do not use the platform controls to free a platform
that is caught, snagged or otherwise prevented
from normal motion by an adjacent structure. All
personnel must be removed from the platform
before attempting to free the platform using the
ground controls.
Do not push off or pull
toward any object outside
of the platform.
Maximum allowable side force 400 N
Do not tie the platform to adjacent structures.
Do not place loads outside the platform perimeter.
Do not alter or disable machine components that in
any way affect safety and stability.
Do not modify or alter an aerial work platform
without prior written permission from the
manufacturer. Mounting attachments for holding
tools or other materials onto the platform,
toeboards or guard rail system can increase the
weight in the platform and the surface area of the
platform or the load.
Do not replace items critical to machine stability
with items of different weight or specification.
Do not raise the platform when wind speeds may
exceed 12.5 m/s. If wind speeds exceed 12.5 m/s
when the platform is raised, lower the platform and
do not continue to operate the machine.
Do not operate the
machine in strong or gusty
winds. Do not increase the
surface area of the
platform or the load.
Increasing the area
exposed to the wind will
decrease machine
stability.

obstructions.
Limit travel speed
according to the condition
of the ground surface,
congestion, slope,
location of personnel, and
any other factors which
may cause collision.
Do not operate a machine in the path of any crane
or moving overhead machinery unless the controls
of the crane have been locked out and/or

Do not lower the outriggers unless the machine is
on a firm surface. Avoid drop-offs, holes, unstable
or slippery surfaces and other possible hazardous
conditions.
When the auto level function is not being used and
the outriggers are being lowered individually, the
steer-end outriggers must be lowered first.
Do not raise the platform unless the machine is
level. Do not set the machine up on a surface
where it cannot be leveled using only the
outriggers.
Do not raise the platform unless all four outriggers
are properly lowered, the footpads are in firm
contact with the ground and the machine is level.
Do not adjust the outriggers while the platform is
raised.
Do not drive while the outriggers are lowered.

battery acid. Neutralize battery
acid spills with baking soda
and water.
Do not expose the batteries or the charger to water
or rain during charging.
Explosion Hazards
Keep sparks, flames and
lighted tobacco away from
batteries. Batteries emit
explosive gas.
The battery tray should
remain open during the entire
charging cycle.
Do not contact the battery
terminals or the cable clamps
with tools that may cause
sparks.
