1.3 OPERATION
General
• Do not use the machine for any purpose other than posi-
tioning personnel, their tools, and equipment.
• Never operate a machine that is not working properly. If a
malfunctions occurs, shut down the machine.
• 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. Oper-
ate controls 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.
• Do not carry materials directly on platform railing. Contact
JLG for approved material handling accessories.
• When two or more persons are in the platform, the opera-
tor 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.
• Supplies or tools which extend outside the platform are
prohibited unless approved by JLG.
• 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,
pulling, or by using boom functions. Only pull the unit
from the tie-down lugs on the chassis.
• Do not place boom or platform against any structure to
steady the platform or to support the structure.
• Stow boom and shut off all power before leaving machine.
Trip and Fall Hazards
During operation, occupants in the platform must wear a full
body harness with a lanyard attached to an authorized lan-
yard anchorage point. Attach only one (1) lanyard per lan-
yard anchorage point.

1-4 – JLG Lift – 3121138
• 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 use ladders, boxes, steps, planks, or similar
items on platform to provide additional reach.
• Never use the boom assembly to enter or leave the plat-
form.
• Use extreme caution when entering or leaving platform.
Be sure that the boom is fully lowered. It may be neces-
sary to telescope out to position the platform closer to the
ground for entry/exit. Face the machine, maintain “three
point contact” with the machine, using two hands and one
foot or two feet and one hand during entry and exit.
Electrocution Hazards
• This machine is not insulated and does not provide pro-
tection 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
to 50,000 volts. One foot additional clearance is required for
every additional 30,000 volts or less.

1-6 – JLG Lift – 3121138
• The minimum approach distance may be reduced if insulat-
ing 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
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 per-
son 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
• The user must be familiar with the surface before driving.
Do not exceed the allowable sideslope and grade while
driving.

SECTION 1 - SAFETY PRECAUTIONS
3121138 – JLG Lift – 1-7
• Do not elevate platform or drive with platform elevated
while on a sloping, uneven, or soft surface.
• Before driving on floors, bridges, trucks, and other sur-
faces, check allowable capacity of the surfaces.
• Never exceed the maximum platform capacity. Distribute
loads evenly on platform floor.
• Do not raise the platform or drive from an elevated posi-
tion unless the machine is on firm, level and smooth sur-
faces.
• Keep the chassis of the machine at least 2 ft. (0.6m) from
holes, bumps, drop-offs, obstructions, debris, concealed
holes, and other potential hazards on the floor/surface.
• 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.
• Do not operate the machine when wind conditions exceed
28 mph (12.5 m/s). Refer to Table 1-2, Beaufort Scale (For
Reference Only).
• Do not increase the surface area of the platform or the
load. Increase of the area exposed to the wind will
decrease stability.
• Do not increase the platform size with unauthorized deck
extensions or attachments.
• 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.
Crushing and Collision Hazards
• Approved head gear must be worn by all operating and
ground personnel.
• Check work area for clearances overhead, on sides, and
bottom of platform when lifting or lowering platform, and
driving.
• During operation, keep all body parts inside platform rail-
ing.

SECTION 1 - SAFETY PRECAUTIONS
1-8 – JLG Lift – 3121138
• Use the boom functions, not the drive function, to position
the platform close to obstacles.
• 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 and swing operations.
• Limit travel speed according to conditions of ground sur-
face, congestion, visibility, slope, location of personnel,
and other factors which may cause collision or injury to
personnel.
• Be aware of stopping distances in all drive speeds. When
driving in high speed, switch to low speed before stop-
ping. 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.
• Be sure that operators of other overhead and floor level
machines are aware of the aerial work platform’s pres-
ence. Disconnect power to overhead cranes.
• Warn personnel not to work, stand, or walk under a raised
boom or platform. Position barricades on floor if neces-
sary.
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 the Emergency Procedures section of this
manual for emergency towing procedures.
• Ensure boom is in the stowed position and the turntable
locked prior to towing, lifting or hauling. The platform must
be completely empty of tools.
• When lifting machine, lift only at designated areas of the
machine. Lift the unit with equipment of adequate capac-
ity.
• Refer to the Machine Operation section of this manual for
lifting information.
