• 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.

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.

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 3121713
• 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.

• 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.

• Maintain distance from electrical lines, apparatus, or any ener-
gized (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 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.

• The minimum approach distance may be reduced if insulating
barriers are installed to prevent contact, and the barriers are
rated for the voltage of the line being guarded. These barriers
shall not be part of (or attached to) the machine. The mini-
mum 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 require-
ments 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 OTH-
ERWISE.
Tipping Hazards
• The user must be familiar with the 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 elevat-
ing platform or driving with the platform in the elevated posi-
tion.
• 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, concealed
holes, and other potential hazards at the ground level.
• Do not push or pull any object with the boom.
• 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.
• If boom assembly or platform is in a position that one or more
wheels are off the ground, all persons must be removed before
attempting to stabilize the machine. Use cranes, forklift trucks,
or other appropriate equipment to stabilize machine.
• Do not operate the machine when wind conditions, including
gusts, may exceed 28 mph (12.5 m/s). Factors affecting wind
speed are; platform elevation, surrounding structures, local
weather events, and approaching storms. Refer to Table 1-2,
Beaufort scale (For Reference Only) or use other means to
monitor wind conditions.
• Wind speed can be significantly greater at height than at
ground level.
• Wind speed can change rapidly. Always consider approaching
weather events, the time required to lower the platform, and
methods to monitor current and potential wind conditions.
• Do not increase surface area of the platform or the load.
Increased areas exposed to wind will decrease stability.
• Do not increase the platform size with unauthorized modifica-
tions or attachments.
