•
Ensure machine is positioned on a smooth, firm surface within the limits of the
maximum operating slope before elevating platform or driving with the platform in
the elevated position.
•
Before driving on floors, bridges, trucks, and other surfaces, check allowable capacity
of the surfaces.
•
Never exceed the maximum platform capacity as specified on the platform. Keep all
loads within the confines of the platform, unless authorized by JLG.
•
Keep the chassis of the machine a minimum of 2 ft (0.6m) from holes, bumps, drop-
offs, obstructions, debris, concealed holes, and other potential hazards at the ground
level.
•
Do not push or pull any object with the boom.
•
Never attempt to use the machine as a crane. Do not tie-off machine to any adjacent
structure. Never attach wire, cable, or any similar items to platform.
•
If boom assembly or platform is in a position that one or more wheels are off the
ground, all persons must be removed before attempting to stabilize the machine.
Use cranes, forklift trucks, or other appropriate equipment to stabilize machine.
•
Do not operate the machine when wind conditions, including gusts, exceed 28 mph
(12.5 m/s). Refer to
affecting wind speed are; platform elevation, surrounding structures, local weather
events, and approaching storms.
•
Wind speed can be significantly greater at height than at ground level.
•
Wind speed can change rapidly. Always consider approaching weather events, the
time required to lower the platform, and methods to monitor current and potential
wind conditions.
•
Do not cover or increase surface area of the platform or the load. Do not carry large
surface area items in the platform when operating outdoors. The addition of such
items increases the exposed wind area of the machine. Increased areas exposed to
wind will decrease stability.
•
Do not increase the platform size with unauthorized modifications or attachments.
Do not operate the machine when wind conditions exceed specifications shown in
the General Specifications section of this manual or as shown on the capacity
placard on the platform billboard.
