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 at the
platform controls and the
ground controls 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 drive over 0.5 mph / 0.8 km/h with the
platform raised.
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.
Follow ratings for allowable side force and number
of occupants shown below.
Outdoor use: Do not operate the machine
outdoors with the indoor use button selected.
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.
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 drive the machine on or near uneven
terrain, unstable surfaces or other hazardous
conditions with the platform raised.
Do not use the machine as a crane.
Do not push the machine or other objects with the
platform.
Do not contact adjacent structures with the
platform.
Do not tie the platform to adjacent structures.
Do not place loads outside the platform perimeter.
The work station tray is considered part of the

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 alter or disable the limit switches.
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 use batteries that weigh less than the
original equipment. Batteries are used as
counterweight and are critical to machine stability.
Each battery must weigh a minimum of
62 lbs/28 kg.
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

Do not use the machine on
a moving or mobile surface
or vehicle.
Be sure all tires are in good
condition, castle nuts are
properly tightened and
cotter pins are properly
installed.
Crushing Hazard
Keep hands and limbs out of mast.
Do not work under the platform or mast without the
battery cover raised.
Use common sense and planning when operating
the machine with the controller from the ground.
Maintain safe distances between the operator, the
machine and fixed objects.
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.
Maximum slope rating, stowed
position
30% (16.7°)
Maximum side slope rating, stowed
position
30% (16.7°)
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.
Keep the platform floor clear of debris.
Close the entry gate before operating.
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.

unless the area below is
clear of personnel and
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.
Observe and use color-coded direction arrows on
the platform controls and the platform decal plate
for drive and steer functions.
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
precautions have been taken to prevent any
potential collision.
No stunt driving or horseplay while operating a
machine.
