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 0.8 km/h with the platform raised.
When raising the platform, follow ratings for
allowable manual force and number of occupants
on the next page.
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.
The machine is rated for
indoor use only. Do not
raise the platform when
wind speeds may exceed
0 m/s
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
platform.
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.

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.

Maximum side slope rating, stowed
position
30% (17°)
Note: Slope rating is subject to ground conditions
and adequate traction.
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. Attach the lanyard to the anchor
provided in the platform.

terminals or the cable
clamps with tools that may
cause sparks.
Component Damage Hazard
Do not use any battery charger greater than 24V to
charge the batteries.
Do not use the machine as a ground for welding.
Electrocution/Burn Hazards
Connect the battery charger to a
grounded, AC 3-wire electrical
outlet only.
Inspect daily for damaged cords,
cables and wires. Replace
damaged items before operating.
Avoid electrical shock from contact with battery
terminals. Remove all rings, watches and other
jewelry.
Tip-over Hazard
