1.3 OPERATION
General
• Machine operation requires your full attention. Bring the
machine to a full stop before using any device, i.e. cell phones,
two-way radios, etc. that will distract your attention from
safely operating the machine.
• Do not use the machine for any purpose other than position-
ing personnel, their tools, and equipment.
• Before operation, the user must be familiar with the machine
capabilities and operating characteristics of all functions.
• Never operate a malfunctioning machine. If a malfunction
occurs, shut down the machine. Remove the unit from service
and notify the proper authorities.
• Do not remove, modify, or disable any safety devices.
• Never slam a control switch or lever through neutral to an
opposite direction. Always return switch to neutral and stop
before moving the switch to the next function. Operate con-
trols with slow and even pressure.
• Do not allow personnel to tamper with or operate the
machine from the ground with personnel in the platform,
except in an emergency.
• Do not carry materials directly on platform railing unless
approved by JLG.
• When two or more persons are in the platform, the operator
shall be responsible for all machine operations.
• Always ensure that power tools are properly stowed and never
left hanging by their cord from the platform work area.
• Do not assist a stuck or disabled machine by pushing or pull-
ing except by pulling at the chassis tie-down lugs.
• Fully lower platform and shut off all power before leaving

the maximum tire load indicated on the tire load decals
located on the chassis adjacent to each wheel. Do not travel
on unsupported surfaces.
• The user must be familiar with the operating surface before
driving. Do not exceed the allowable sideslope and grade
while driving
• Do not elevate platform or drive with platform elevated while
on or near a sloping, uneven, or soft surface. Ensure machine is
positioned on a smooth, firm surface within the limits of the
maximum operating slope before elevating platform or driv-
ing 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 plat-
form, unless authorized by JLG.
• Keep the chassis of the machine a minimum of 0.6 m (2 ft)
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
specifications shown in Section 6.2 or as shown on the capac-
ity placard on the platform billboard. Factors 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 modifica-
tions, deck extensions, or attachments.

• Always post a lookout when driving in areas where vision is
obstructed.
• Keep non-operating personnel at least 6 ft (1.8 m) away from
machine during all driving operations.
• Under all travel conditions, the operator must limit travel
speed according to conditions of ground surface, congestion,
visibility, slope, location of personnel, and other factors caus-
ing hazards of collision or injury to personnel.
• Be aware of stopping distances in all drive speeds. When driv-
ing in high speed, reduce drive speed before stopping. Travel
grades in low speed only.
• Do not use high speed drive in restricted or close quarters or
when driving in reverse.
