Tipping Hazards
•Ensure that the ground conditions are adequate to support the
maximum tire load indicated on the tire load decals located on the
chassis adjacent to each wheel. Do not travel on unsupported sur-
faces.
•The user must be familiar with the operating surface before driv-
ing. Do not exceed the allowable sideslope and grade while driv-
ing.
•Do not elevate platform or drive with platform elevated while on
or near a sloping, uneven, or soft surface. Ensure machine is posi-
tioned on a smooth, firm surface within the limits of the maximum
operating slope before elevating platform or driving with the plat-
form 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 (0.6 m) from
holes, bumps, drop-offs, obstructions, debris, concealed holes,
and other potential hazards at the ground level.
•Do not operate the machine when wind conditions exceed specifi-
cations shown in Section 6.2 or as shown on the capacity placard
on the platform billboard. Factors affecting wind speed are: plat-
form 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 operat-
ing 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 modifica-
tions, deck extensions, or attachments.
