FOREWORD
IT IS A GOOD PRACTICE TO AVOID PRESSURE-WASHING ELECTRICAL/ELECTRONIC COMPONENTS. SHOULD
PRESSURE-WASHING BE UTILIZED TO WASH AREAS CONTAINING ELECTRICAL/ELECTRONIC COMPONENTS,
JLG INDUSTRIES, INC. RECOMMENDS A MAXIMUM PRESSURE OF 750 PSI (52 BAR) AT A MINIMUM DIS-
TANCE OF 12 INCHES (30.5 CM) AWAY FROM THESE COMPONENTS. IF ELECTRICAL/ELECTRONIC COMPO-
NENTS ARE SPRAYED, SPRAYING MUST NOT BE DIRECT AND BE FOR BRIEF TIME PERIODS TO AVOID HEAVY
SATURATION.
This manual is a very important tool! Keep it with the machine at all times.
The purpose of this manual is to provide owners, users, operators, lessors, and lessees with the precautions and
operating procedures essential for the safe and proper machine operation for its intended purpose.
Due to continuous product improvements, JLG Industries, Inc. reserves the right to make specification changes

1.3 OPERATION
General
•Do not use the machine for any purpose other than posi-
tioning 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 ser-
vice 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, other than the outrigger 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 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
pulling except by pulling at the chassis tie-down lugs.
•Stow platform assembly and shut off all power before leav-
ing machine.

Trip and Fall Hazards
•JLG Industries, Inc. recommends that all persons in the plat-
form 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 products, contact JLG Industries, Inc.
•Prior to operation, ensure all gates and rails are fastened
and secured in their proper position. Identify the desig-
nated lanyard anchorage point(s) at the platform and
securely attach the lanyard. Attach only one (1) lanyard per
lanyard anchorage point
•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.
.
•Keep both feet firmly positioned on the platform floor at all
times. Never position ladders, boxes, steps, planks, or simi-
lar items on unit to provide additional reach for any pur-
pose.
•Keep oil, mud, and slippery substances cleaned from foot-
wear and the platform floor.

Electrocution Hazards •This machine is not insulated and does not provide protec-
tion from contact or proximity to electrical current.
•Maintain distance from electrical lines, apparatus, or any
energized (exposed or insulated) parts according to the
Minimum Approach Distance (MAD) as shown in Table 1-1.
•Allow for machine movement and electrical line swaying.
•Maintain a clearance of at least 10 ft. (3m) between any part
of the machine and its occupants, their tools, and their
equipment from any electrical line or apparatus carrying up
Table 1-1. Minimum Approach Distances (M.A.D.)

to 50,000 volts. One foot 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 the barri-
ers are rated for the voltage of the line being guarded.
These barriers shall not be part of (or attached to) the
machine. The minimum 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 the employer, local,
or governmental requirements for work practices near
energized equipment
DO NOT MANEUVER MACHINE OR PERSONNEL INSIDE PROHIBITED ZONE
(MAD). ASSUME ALL ELECTRICAL PARTS AND WIRING ARE ENERGIZED
UNLESS KNOWN OTHERWISE.

Tipping Hazards •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.
•The user should be familiar with the driving 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 firm, level and smooth surface
before elevating platform or driving 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 work load as specified on the
platform. Keep all loads within the confines of the platform,
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 stopping.
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 presence.
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. Position
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.
