elevated position.
• Before driving on floors, bridges, trucks, and other sur-
faces, check allowable capacity of the surfaces.
• Never exceed the maximum work load 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 2 ft. (0.6m)
from holes, bumps, drop-offs, obstructions, debris, con-
cealed holes, and other potential hazards at the ground
level.
• 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.

SECTION 1 - SAFETY PRECAUTIONS
3121221 – JLG Lift – 1-9
• Do not cover the platform sides or carry large surface-area
items in the platform when operating outdoors. The addi-
tion of such items increases the exposed wind area of the
machine.
• Do not increase the platform size with unauthorized deck
extensions or attachments.
• If mast assembly or platform is caught so that one or more
wheels are off the ground, all persons must be removed
before attempting to free the machine. Use cranes, forklift
trucks, or other appropriate equipment to stabilize
machine and remove personnel.
Crushing and Collision Hazards
• Approved head gear must be worn by all operating and
ground personnel.
• Keep hands and limbs off of the mast assembly during
operation.
• Watch for obstructions around machine and overhead
when driving. Check clearances above, on sides, and bot-
tom of platform when lifting or lowering platform.

SECTION 1 - SAFETY PRECAUTIONS
1-10 – JLG Lift – 3121221
• During operation, keep all body parts inside platform rail-
ing.
• Always post a lookout when driving in areas where vision
is obstructed.
• Keep non-operating personnel at least 6 ft. (1.8m) away
from machine during all driving operations.
• Under all travel conditions, the operator must limit travel
speed according to conditions of ground surface, conges-
tion, visibility, slope, location of personnel, and other fac-
tors causing hazards of collision or injury to personnel.
• Be aware of stopping distances in all drive speeds. When
driving in high speed, switch to low speed before stop-
ping. Travel grades in low speed only.
• Do not use high speed drive in restricted or close quarters
or when driving in reverse.
• Exercise extreme caution at all times to prevent obstacles
from striking or interfering with operating controls and per-
sons in the platform.
• Ensure that operators of other overhead and floor level
machines are aware of the aerial work platform’s pres-
ence. Disconnect power to overhead cranes. Barricade
floor area if necessary.
• Avoid operating over ground personnel. Warn personnel
not to work, stand, or walk under a raised platform. Posi-
tion barricades on floor as necessary.
1.4 TOWING, LIFTING, AND HAULING
• Never allow personnel in platform while towing, lifting, or
hauling.
• This machine should not be towed, except in the event of
emergency, malfunction, power failure, or loading/unload-
ing. Refer to emergency towing procedures.
• Ensure platform is fully retracted and completely empty of
tools prior to towing, lifting or hauling.
• When lifting machine with a forklift, position forks only at
designated areas of the machine. Lift with a forklift of ade-
quate capacity.
• Refer to Section 4 for lifting information.
