SECTION 1 - SAFETY PRECAUTIONS
3121211 – JLG Lift – 1-1
SECTION 1. SAFETY PRECAUTIONS
1.1 GENERAL
This section outlines the necessary precautions for proper and
safe machine operation and maintenance. For proper machine
use, it is mandatory that a daily routine is established based on
the content of this manual. A maintenance program using the
information provided in this manual and the Service and Main-
tenance Manual must also be established by a qualified person
and followed to ensure that the machine is safe to operate.
The owner/user/operator/lessor/lessee of the machine should
not operate the machine until this manual has been read, train-
ing is accomplished, and operation of the machine has been
completed under the supervision of an experienced and quali-
fied operator. If there is a question with regard to safety training,
inspection, maintenance and operation, please contact JLG
Industries, Inc. ("JLG").
MODIFICATION OR ALTERATION OF AN AERIAL WORK PLATFORM SHALL BE
MADE ONLY WITH PRIOR WRITTEN PERMISSION FROM THE MANUFACTURER.
1.2 TRANSPORTING
FAILURE TO COMPLY WITH SAFETY PRECAUTIONS LISTED IN THIS SECTION
AND ON MACHINE MAY RESULT IN MACHINE DAMAGE, PERSONNEL INJURY
OR DEATH AND IS A SAFETY VIOLATION.
Transport
•The platform must be completely empty of tools and
debris.
•Ensure platform is fully lowered. Remove and stow outrig-
gers.
•Never allow personnel in platform while moving machine.
•To move machine use handles provided on the mast cross-
bar.

SECTION 1 - SAFETY PRECAUTIONS
1-2 – JLG Lift – 3121211
Tipping Hazards
FAILURE TO COMPLY WITH THE FOLLOWING TIPPING HAZARD INSTRUCTIONS
COULD CAUSE THE UNIT TO TIP OVER OR BE HARD TO CONTROL WHEN BEING
MOVED, WHICH COULD RESULT IN SERIOUS INJURY OR DEATH.
•On a level surface, always travel with the platform end lead-
ing the way.
•Watch for obstructions around machine and overhead.
•Check travel path for persons, holes, bumps, drop-offs,
obstructions, debris, and coverings which may conceal
other hazards.
•Before placing machine on floors, trucks and other surfaces,
check allowable capacity of surfaces.

SECTION 1 - SAFETY PRECAUTIONS
3121211 – JLG Lift – 1-3
•Two persons are required on slopes up to 5°. A forklift must
be used when moving units on slopes greater than 5°.
•Always travel up or down a slope with the platform end of
the machine positioned towards the low side of the slope.
the operator and assistant must walk beside to guide the
machine.
•Never position the unit sideways on a slope.
•Do not elevate the platform or move the machine on a soft
surface.
•Use caution and check clearances when moving machine in
restricted or close quarters.
•Always use an assistant when moving machine in areas
where vision is obstructed.
•Keep non-operating personnel at least 6 feet (1.8 m) away
from machine during moving operations.

SECTION 1 - SAFETY PRECAUTIONS
1-4 – JLG Lift – 3121211
Tilt Back Procedure
(AM36 & AM41 Machines Only)
•The platform must be completely empty of tools and
debris.
•Ensure platform is fully lowered. Remove and stow outrig-
gers.
•Tilt machine back only on a flat, firm and level surface.

SECTION 1 - SAFETY PRECAUTIONS
3121211 – JLG Lift – 1-5
1.3 PRE-OPERATION
General
•Read and understand this manual before operating the
machine.
•Only authorized and qualified personnel can operate the
machine.
•Do not operate this machine until complete training is per-
formed by authorized personnel.
•Before operation check work area for machine traffic such
as forklifts, cranes, and other construction equipment.
•Set-up machine for operation only on a smooth, firm sur-
face on which the machine is capable of being leveled.
•Be sure that operators of other overhead and floor level
machines are aware of the aerial work platform’s presence.
Disconnect power to overhead cranes.
•The operator is to take safety measures to avoid all hazards
in the work area prior to machine operation.
•Do not operate this machine until it has been serviced and
maintained according to requirements specified in the Ser-
vice and Maintenance manual.
•Before machine operation perform inspections and func-
tional checks. Refer to in Section 2 of this manual for
detailed instructions.

SECTION 1 - SAFETY PRECAUTIONS
1-6 – JLG Lift – 3121211
•Warn personnel not to work, stand, or walk under a raised
platform. Position barricades on floor, if necessary.
•Be sure all safety devices are operating properly. Modifica-
tion of these devices is a safety violation.
•Never operate machine in high wind, rain or snow.
•Do not operate or raise the platform while on trucks, trail-
ers, railway cars, floating vessels, scaffolds or other equip-
ment unless approved by JLG.
•Approved head gear must be worn by all operating and
ground personnel.
•Read, understand, and obey all dangers, warnings, cautions
and operating instructions on the machine and in this man-
ual.
•All operating personnel must be familiar with emergency
controls and emergency operation of the machine as speci-
fied in this manual.

SECTION 1 - SAFETY PRECAUTIONS
3121211 – JLG Lift – 1-7
Maintain a clearance of at least 10 ft (3m) between any part of
the machine and its occupants, their tools, and their equip-
ment from any electrical line or apparatus carrying up to
50,000 volts. One foot (0.3m) additional clearance is required
for every additional 30,000 volts or less.
The minimum approach distance may be reduced if insulat-
ing barriers are installed to prevent contact, and if the barriers
are rated for the voltage of the line being guarded. These bar-
riers shall not be part of (or attached to) the machine. The min-
imum approach distance shall be reduced to a distance within
the designed working dimensions of the insulating barrier.
This determination shall be made by a qualified person in
accordance with employer, local, or governmental require-
ments for work practices near energized equipment.
1.4 OPERATION
•Do not operate any machine on which instruction placards
or decals are missing or illegible.
•Never exceed the maximum platform capacity.
•Operate AC units with an extension cord rated at a mini-
mum of 15 amps.
•Prior to entering the platform ensure all leveling jacks have
been properly installed and the unit’s base frame is level
according to the bubble leveling indicator on base frame,
and all wheels are completely off the ground.
•While operating the machine, always look in the direction
of machine movement.
•Never operate a machine that is not operating properly. If a
malfunction occurs, shut down the machine.
•When applicable by reason of local regulations or job-site/
employer safety rules, personnel in the platform shall at all
times wear approved fall protection devices. The autho-
rized lanyard attachment is on the side of the machine’s
mast.

SECTION 1 - SAFETY PRECAUTIONS
1-8 – JLG Lift – 3121211
•Check work area for clearance overhead, on sides, and bot-
tom of platform when lifting and lowering platform.
•Never use the mast assembly to enter or leave the platform.
•Do not increase the platform size with unauthorized deck
extensions or attachments.
•Never attempt to use the machine as a crane.
•Do not tie off machine to any adjacent structure.

SECTION 1 - SAFETY PRECAUTIONS
3121211 – JLG Lift – 1-9
•Platform to structure transfers at elevated positions are dis-
couraged. Where transfer is necessary, enter and exit
