SECTION 1. SAFETY PRECAUTIONS
1.1 GENERAL
This section outlines the necessary precautions for proper and
safe machine usage and maintenance. It is mandatory that a daily
routine is established based on the content of this manual to pro-
mote proper machine usage. A maintenance program, using the
information provided in this manual and the Service and Mainte-
nance Manual, must also be established by a qualified person and
must be followed to ensure that the machine is safe to operate.
The owner/user/operator/lessor/lessee of the machine must not
accept operating responsibility until this manual has been read,
training is accomplished, and operation of the machine has been
completed under the supervision of an experienced and quali-
fied operator.
This section contains the responsibilities of the owner, user, oper-
ator, lessor, and lessee concerning safety, training, inspection,
maintenance, application, and operation. If there are any ques-
tions with regard to safety, training, inspection, maintenance,
application, and operation, please contact JLG Industries, Inc.
(“JLG”).
FAILURE TO COMPLY WITH THE SAFETY PRECAUTIONS LISTED IN THIS MANUAL
COULD RESULT IN MACHINE DAMAGE, PROPERTY DAMAGE, PERSONAL INJURY OR
DEATH.
1.2 PRE-OPERATION
Operator Training and Knowledge
• The Operation and Safety Manual must be read and under-
stood in its entirety before operating the machine. For clarifi-
cation, questions, or additional information regarding any
portions of this manual, contact JLG Industries, Inc.

SECTION 1 - SAFETY PRECAUTIONS
1-2 – JLG Lift – 3121670
• An operator must not accept operating responsibilities until
adequate training has been given by competent and autho-
rized persons.
• Allow only those authorized and qualified personnel to oper-
ate the machine who have demonstrated that they under-
stand the safe and proper operation and maintenance of the
unit.
• Read, understand, and obey all DANGERS, WARNINGS, CAU-
TIONS, and operating instructions on the machine and in this
manual.
• Ensure that the machine is to be used in a manner which is
within the scope of its intended application as determined by
JLG.
• All operating personnel must be familiar with the emergency
controls and emergency operation of the machine as specified
in this manual.
• Read, understand, and obey all applicable employer, local, and
governmental regulations as they pertain to your utilization
and application of the machine.
Workplace Inspection
• Precautions to avoid all hazards in the work area must be
taken by the user before and during operation of the machine.
• Do not operate or raise the platform from a position on trucks,
trailers, railway cars, floating vessels, scaffolds or other equip-
ment unless the application is approved in writing by JLG.
• Before operation, check work area for overhead hazards such
as electric lines, bridge cranes, and other potential overhead
obstructions.
• Check operating surfaces for holes, bumps, drop-offs, obstruc-
tions, debris, concealed holes, and other potential hazards.
• Check the work area for hazardous locations. Do not operate
the machine in hazardous environments unless approved for
that purpose by JLG.
• 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 surfaces.

SECTION 1 - SAFETY PRECAUTIONS

Machine Inspection
• Do not operate this machine until the inspections and func-
tional checks as specified in Section 2 of this manual have
been performed.
• Do not operate this machine until it has been serviced and
maintained according to the maintenance and inspection
requirements as specified in the machine’s Service and Main-
tenance Manual.
• Ensure all safety devices are operating properly. Modification
of these devices is a safety violation.
MODIFICATION OR ALTERATION OF AN AERIAL WORK PLATFORM SHALL BE MADE
ONLY WITH PRIOR WRITTEN PERMISSION FROM THE MANUFACTURER.
• Do not operate any machine on which the safety or instruction
placards or decals are missing or illegible.
• Check the machine for modifications to original components.
Ensure that any modifications have been approved by JLG.
• Avoid accumulation of debris on platform floor. Keep mud, oil,
grease, and other slippery substances from footwear and plat-
form floor.
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.

SECTION 1 - SAFETY PRECAUTIONS
1-4 – JLG Lift – 3121670
• 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.
• When driving, always position boom over rear axle in line with
the direction of travel. Remember, if boom is over the front
axle, steer and drive functions will be reversed.
• 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
machine.
• Remove all rings, watches, and jewelry when operating
machine. Do not wear loose fitting clothing or long hair unre-
strained which may become caught or entangled in equip-
ment.
• Persons under the influence of drugs or alcohol or who are
subject to seizures, dizziness or loss of physical control must
not operate this machine.
• Hydraulic cylinders are subject to thermal expansion and con-
traction. This may result in changes to the boom and/or plat-
form position while the machine is stationary. Factors
affecting thermal movement can include the length of time
the machine will remain stationary, hydraulic oil temperature,
ambient air temperature, and boom and platform position.
Trip and Fall Hazards
• During operation, occupants in the platform must wear a full
body harness with a lanyard attached to an authorized lanyard
anchorage point. Attach only one (1) lanyard per lanyard
anchorage point.
• Enter and exit only through gate area. Use extreme caution
when entering or leaving platform. Ensure that the platform
assembly is fully lowered. Face the machine when entering or
leaving the platform. Always maintain “three point contact”
with the machine, using two hands and one foot or two feet
and one hand at all times during entry and exit.

SECTION 1 - SAFETY PRECAUTIONS

• Before operating the machine, make sure all gates are closed
and fastened in their proper position.
• Keep both feet firmly positioned on the platform floor at all
times. Never position ladders, boxes, steps, planks, or similar
items on unit to provide additional reach for any purpose.
• Keep oil, mud, and slippery substances cleaned from footwear
and the platform floor.
Electrocution Hazards
• This machine is not insulated and does not provide protection
from contact or proximity to electrical current.

SECTION 1 - SAFETY PRECAUTIONS

• 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 additional clearance is required for
every additional 30,000 volts or less.
