3121165 –JLG Lift –1-1
SECTION 1. SAFETY PRECAUTIONS
1.1 GENERAL
This section outlines the necessary precautions for proper
and safe machine usage and maintenance. In order to
promote proper machine usage, 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 Maintenance
Manual, must also be established by a qualified person
and must be followed to ensure that the machine is safe to

ual has been read, training is accomplished, and opera-
tion of the machine has been completed under the
supervision of an experienced and qualified operator.
These sections contain the responsibilities of the owner,
user, operator, lessor, and lessee concerning safety, train-
ing, inspection, maintenance, application, and operation.If
there are any questions 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, PROP-
ERTY DAMAGE, PERSONAL INJURY OR DEATH.
1.2 PRE-OPERATION
Operator Training and Knowledge
•The Operators and Safety Manual must be read in its
entirety before operating the machine. For clarification,
questions, or additional information regarding any por-
tions of this manual, contact JLG Industries, Inc.
•An operator must not accept operating responsibilities
until adequate training has been given by competent
and authorized persons.
•Allow only those authorized and qualified personnel to
operate the machine who have demonstrated that they
understand the safe and proper operation and mainte-
nance of the unit.
•Read, understand, and obey all DANGERS, WARN-
INGS, CAUTIONS, 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 emer-
gency 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 operation of the machine.
•Do not operate or raise the platform from a position on
trucks, trailers, railway cars, floating vessels, scaffolds
or other equipment unless the application is approved
in writing by JLG.
•Before operation, check work area for overhead haz-
ards such as electric lines, bridge cranes, and other
potential overhead obstructions.
•Check floor surfaces for holes, bumps, drop-offs,
obstructions, 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 operate the machine when wind conditions
exceed 28 mph (12.5 m/s).
•This machine can be operated in nominal ambient tem-
peratures of 0oF to 104oF (-20oC to 40oC). Consult
JLG to optimize operation outside of this temperature
range.
Machine Inspection
•Do not operate this machine until the inspections and
functional checks have been performed as specified in
Section 2 of this manual.

SECTION 1 - SAFETY PRECAUTIONS
1-2 –JLG Lift –3121165
•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 Maintenance Manual.
•Ensure all safety devices are operating properly. Modi-
fication of these devices is a safety violation.
MODIFICATION OR ALTERATION OF AN AERIAL WORK PLAT-
FORM SHALL BE MADE ONLY WITH PRIOR WRITTEN PERMIS-
SION 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 com-
ponents. Ensure that any modifications have been
approved by JLG.
•Avoid accumulation of debris on platform deck. Keep
mud, oil, grease, and other slippery substances from
footwear and platform deck.
1.3 OPERATION
General
•Do not use the machine for any purpose other than
positioning 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 malfunc-
tion 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 controls with slow and even pressure.
•Hydraulic cylinders should never be left at end of travel
(fully extended or fully retracted) before shutdown or
for long periods of time. Always “bump”control in
opposite direction slightly when function reaches end
of travel. This applies both to machines in operation or
in the stowed position.
•Do not allow personnel to tamper with or operate the
machine from the ground with personnel in the plat-
form, 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 opera-
tions.
•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 pulling except by pulling at the chassis tie-down
lugs.
•Stow scissor arm assembly and shut off all power
before leaving machine.
Trip and Fall Hazards
•JLG Industries, Inc. recommends that all persons in the
platform wear a full body harness with a lanyard
attached to an authorized lanyard anchorage point
while operating this machine. For further information
regarding fall protection requirements on JLG prod-
ucts, contact JLG Industries, Inc.
•Prior to operation, ensure all gates and rails are fas-
tened and secured in their proper position. Identify the
designated lanyard anchorage point(s) at the platform
and securely attach the lanyard. Attach only one (1)
lanyard per lanyard anchorage point.
•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.
•Never use the scissor arm assembly to gain access to
or leave the platform.
