Do not raise the platform
unless the machine is on a
firm, level surface.
Do not depend on the tilt alarm as a level indicator.
The tilt alarm sounds on the chassis only when the
machine is on a severe slope.
If the tilt alarm sounds:
Lower the platform. Move 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 or angle
sensor.
Do not drive over 0.7 mph / 1.1 km/h with the
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.

Do not raise the platform when wind speeds may
exceed 28 mph / 12.5 m/s. If wind speeds exceed
28 mph / 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.
Do not drive the machine
on or near uneven terrain,
unstable surfaces or other
hazardous conditions with
the platform raised.
Use extreme care and slow speeds while driving
the machine in the stowed position across uneven
terrain, debris, unstable or slippery surfaces and
near holes and drop-offs.
Do not alter or disable machine components that
in any way affect safety and stability.
Do not replace items critical to machine stability
with items of different weight or specification.
Do not modify or alter a mobile elevating 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 place or attach
fixed or overhanging loads
to any part of this
machine.
Do not place ladders or
scaffolds in the platform or
against any part of this
machine.
Do not transport tools and materials unless they
are evenly distributed and can be safely handled
by person(s) in the platform.
Do not use the machine on a moving or mobile
surface or vehicle.
Be sure all tires are in good condition, air-filled
tires are properly inflated and lug nuts are properly
tightened.

Operation on Slopes Hazards
Do not drive the machine on a slope that exceeds
the slope and side slope rating of the machine.
Slope rating applies to machines in the stowed
position.

Note: Slope rating is subject to ground conditions
with one person in the platform and adequate
traction. Additional platform weight may reduce
slope rating. See Driving on a Slope in the
Operating Instructions section.
Fall Hazards
The guard rail system provides fall protection. If
occupant(s) of the platform are required to wear
personal fall protection equipment (PFPE) due to
job site or employer rules, PFPE and its use shall
be in accordance with the PFPE manufacturer’s
instructions and applicable governmental
requirements. Use approved lanyard attachment
point provided.
Do not sit, stand, or
climb on the platform
guard rails. Maintain a
firm footing on the
platform floor at all
times.
Do not climb down from
the platform when
raised.
Keep the platform floor clear of debris.
Do not enter or exit the platform unless the
machine is in the stowed position.
Attach the platform entry chain or close the entry
gate before operating.
Do not operate the machine unless the guard rails
are properly installed and the entry is secured for
operation.
