OPERATORS PROTECTIVE
STRUCTURE
This vehicles Operators Protective Structure is
equipped with a Roll-Over Protective Structure (ROPS)
to guard the operator if the vehicle tips over. The Falling
Object Protective Structure (FOPS) is built into the
ROPS. The FOPS protects the operator from falling
objects.
Despite the protection of the ROPS/FOPS, it cannot
protect the operator from every possible hazard. Do not
consider the ROPS/FOPS a substitute for safe
practices and good common sense.
Any modification to a ROPS/FOPS, such as welding or
drilling holes in the structural members for mounting
brackets, will affect the ROPS/FOPS capability to
provide the required protection.
CAUTION
The signal word “CAUTION” indicates a
potentially hazardous situation which, if not
avoided, may result in minor or moderate
injury.
CAUTION
The signal word “CAUTION”, used without the
safety alert symbol, indicates a potentially
hazardous situation which, if not avoided, may
result in property damage.
Any modification or repair without the specific written
approval of JLG will void the ROPS/FOPS certification.
Contact your authorized JLG dealer before making any
modifications or repairs. Failure to do so may void the
ROPS/FOPS certification.

This feature eliminates the need to shift to NEUTRAL
before operating the hydraulic system at high engine
speeds. When the transmission is declutched, the
drivetrain is disconnected and the hydraulic system has
full engine power.
To use the Transmission Declutch Feature:
1. The transmission must be in first or second
speed range, forward or reverse. The declutch
feature will not operate when the transmission is
in third speed range.
2. Press the forward side of the transmission
declutch switch.
3. Press the service brake pedal or pull the park
brake knob.
4. The switch will illuminate to show the
transmission clutch has disengaged.
Press the rear side of the switch to deactivate the
declutch feature.

GENERAL OPERATING PROCEDURES
STARTING PROCEDURES
Before operating, walk completely around the vehicle.
Make certain no one is under it, on it or close to it. Let
all other workers and bystanders know you are
preparing to start the vehicle. DO NOT start vehicle until
everyone is clear.
To start engine...
1. Start on level surface.
2. Be properly seated.
3. Set park brake.
4. Move shift selector to NEUTRAL position. Place
the neutral lock lever to NEUTRAL LOCK
position.
5. Apply brakes.
6. Turn ignition switch clockwise, cranking the
engine. (Do not crank the engine longer than 20
seconds. Wait 2 minutes to allow starter to cool
down before trying again.)
7. Allow engine to warm up.
Note: The transmission requires 3 seconds
immediately after engine start for
self-diagnostics. Always wait at least 3 seconds
after engine start before engaging transmission.
8. In cold weather operation, progressively move
each function a small distance back and forth
until full cycle has been accomplished.
SHUTDOWN PROCEDURES
Correct shutdown is important to the safe operation of
the vehicle.
Always follow these steps:
1. Come to a full stop.
2. Set the park brake.
3. Lower boom to the ground. DO NOT leave the
operator’s compartment while the vehicle is
supporting a load.
4. Place transmission shift selector in NEUTRAL
position. Place the neutral lock lever to
NEUTRAL LOCK position.
5. Idle engine for 1–3 minutes for gradual cooling.
This is especially important for turbocharged
engines.
6. Shut off engine.
7. After the engine is shut off, move all hydraulic
levers. If any vehicle movement is detected, a
problem MAY exist and your supervisor should
be advised immediately. DO NOT put the vehicle
into service until the problem has been fixed.
8. Remove ignition key.
9. Lock anti-vandalism covers and closures.
10. Dismount.
11. Block wheels if on a slope or incline.
To make sure warm oil reaches the rear carriage
tilt cylinders, slowly raise and lower the boom
several times. Failure to cycle the rear carriage
tilt cylinders during cold vehicle start-up can
damage the cylinders and structure.
9. Level vehicle, move frame tilt full to the right, then
full to the left, then back to level.
10. Raise boom full up and full down. Extend inner
boom full out and retract full in.
11. Tilt attachment full down and full back.
12. Move transfer carriage full forward and full back.
Note: It is your responsibility to evaluate working
conditions and adjust your operation of the
vehicle accordingly.
TRAVELING
CAUTION
When traveling over rough terrain, soft
ground, or wet/ icy surfaces, slow down and
shift to a lower gear.

CAUSE DEATH OR
SERIOUS PERSONAL
INJURY!
ALWAYS check the load chart mounted in the
vehicle before lifting a load. Lift only within the
capacity of the vehicle as shown by the load chart.
Never tilt the frame when the boom is raised.
Operate the controls smoothly–don't jerk the
hydraulic controls or steering wheel.
Avoid sudden stops, starts, turns or changes in
direction.
Never “cowboy” or play games with a vehicle.
Operate vehicle controls only while seated in the
operator's compartment.
Never leave the operator's seat without first
lowering the boom to the ground, setting the park
brake, and placing transmission in NEUTRAL.
LIFT THE LOAD SAFELY
Important: ALWAYS check the load chart mounted
in the vehicle before lifting a load. Lift
only within the capacity of the vehicle as
shown by the load chart.
1. If possible, plan to load, unload and turn on flat
level ground. If not level, use frame tilt (See
“Frame Tilt Control” on page 24) to level vehicle
before raising the boom. Level indicator MUST
be centered. Be sure there is enough clearance
overhead and all around for lifting and traveling.
Watch the front and rear clearances when
turning.
2. If loads are to be handled several times, place
stacking blocks under loads.
3. For sideshift equipped vehicles, center the forks
and carriage before lifting.
4. Inspect load to be lifted. Approach the load
slowly and squarely with fork tips straight and
level. Adjust pallet forks as necessary.
5. Fully engage the load by moving the transfer
carriage slowly forward until the load touches the
fork carriage backrest.
6. Tilt the forks back to position the load for travel,
then lift the load only enough to clear obstacles.
7. Fully retract the transfer carriage.
TRANSPORT THE LOAD SAFELY
WARNING
Keep all parts of your body inside the
operators compartment while operating the
vehicle. Failure to follow these instructions
may result in death or serious personal
injury.
DO NOT touch, lean on, or reach through the
boom, lift mechanism or transfer carriage areas.
DO NOT permit others to do so. Never climb on
the boom, lift mechanism or transfer carriage.
DO NOT operate a malfunctioning vehicle.
STAY ALERT! Should something break, come
loose, or fail to operate on your vehicle, stop work,
shut down the vehicle and alert your supervisor
immediately.
When transporting the load…
Keep the forks tilted back with boom retracted and
the load close to the ground.
Keep the load as low as possible. Never carry the
load above eye level.
Where the load will obstruct the operator's vision,
it is recommended that the vehicle be operated in
REVERSE, looking backwards in the direction of
travel. Travel at a slower speed and get someone
to direct you.
Avoid excessively steep slopes or unstable
surfaces. If you must drive on a slope, level the
vehicle, keep the load low and proceed with
extreme caution. DO NOT, under any
circumstances, drive across excessively steep
slopes.
The vehicle can be levelled side-to-side a total of
10° in each direction (18% grade). Any slope or
grade that exceeds this is considered excessively
steep.
27
Page 36
GENERAL OPERATING PROCEDURES
If a slope is too steep to allow the frame to be
leveled, do not raise the boom. The frame must
always be level before raising the boom.
WARNING
When traveling over inclines, slopes or
ramps…
Tilt the attachment back and raised only
enough to clear the ground.
Avoid turning. If it cannot be avoided, turn
slowly and with extreme caution.
Travel straight up and down the grades.
When loaded and traveling up or down
grades, travel with the load uphill.
When unloaded, travel only with the forks
or attachment downhill.
Proceed slowly and with extreme caution.
Do not travel across excessively steep
slopes or unstable surfaces.
Failure to follow these instructions may
result in death or serious personal injury.
SAFELY PLACING THE LOAD
Elevated or Overhead Placement
Important: When stacking or placing a load to a
high landing use extreme caution! There
may be other workers in the immediate
area you cannot see. Make sure that all
bystanders are away from the area
where the load could tip or fall.
1. Be sure the landing point can safely support the
weight of the load. The chosen landing location
should be level, both front-to-back and
side-to-side.
You should know or be able to estimate the
weight and load center of the load that you will be
lifting. If you are unsure of the weight and load
center of the load, check with your supervisor or
with the supplier of the material. ALWAYS check
the load chart mounted in the vehicle before
lifting a load. Lift only within the capacity of the
vehicle as shown by the load chart.
2. Drive as close as possible to the landing location.
Approach very slowly with the load as low as
possible.
3. Tilt carriage rearward to cradle the load.
Reduce speed and sound horn at blind
intersections, exits and when approaching
pedestrians.
Slow down for turns, ramps, dips, uneven or
slippery surfaces and in congested areas.
Avoid driving over loose objects and holes in
roadway surfaces to prevent losing the load or
tipping the vehicle.
Avoid crossing ditches, curbs or exposed railroad
tracks. If crossing cannot be avoided, keep the
load as low as possible, travel very slowly, and
proceed with caution.
Avoid panic braking. Apply brakes smoothly for a
controlled stop to prevent toppling the load.
4. Level the vehicle using frame tilt BEFORE the
load is raised. (See “Frame Tilt Control” on page
24) DO NOT raise the load for placement if the
forks are tilted to one side. If the vehicle cannot
be positioned so the load is level before lifting,
reposition the vehicle. The likelihood for vehicle
tipover is greatly increased if the load is not level
before lifting.
WARNING
ALWAYS LEVEL MACHINE
BEFORE RAISING BOOM.
NEVER TILT FRAME WITH
THE BOOM RAISED.
MACHINE MAY TIP AND
CAUSE DEATH OR
SERIOUS PERSONAL
INJURY!
5. Slowly and carefully raise the load. If there is any
indication of instability during the lift (i.e.
movement, leaning, swaying), stop immediately,
lower the load, move the vehicle to a more
stable, level position. As lift height increases,
your depth perception decreases. Placing the
load safely at a high elevation may require a
signalman to guide you.
28
Page 37
GENERAL OPERATING PROCEDURES
6. When the load is slightly higher than the landing
point, SLOWLY stop the lift.
.
WARNING
Do not ram the hydraulic lift cylinder to the
end of its stroke. The jolt could spill the load
resulting in death or serious personal injury.
7. Use the transfer carriage to place the load
directly over the landing point. The transfer
carriage allows safe and easy placement of the
load without moving the vehicle. (Consult load
charts for transfer capacity.) Forks should be
level and parallel to the landing surface so that
they may be easily retracted from under the load.
Before retracting the forks, check landing point
for any excessive bowing, cracking noises or
other indications of overloading. If there is any
indication that the landing surface cannot handle
the weight of the load, place the load at a
different location that you know can handle the
weight. If the landing surface cannot handle the
weight of the load, pick the load back up, lower it
to the ground and lift a lighter load.
LIFTING PERSONNEL
JLG strongly recommends that you DO NOT use the
JLG vehicle as a personnel lift. It is designed for
material handling ONLY. If personnel MUST be lifted,
lift only in accordance with ASME/ANSI B56.6 1992 (or
later), Para. 5.15 and with a properly designed work
platform.
8. Lower the load slowly to place it and relieve the
weight from the forks. Retract the transfer
carriage until the forks are clear of the load.
Lower and retract the boom BEFORE moving the
vehicle.
9. The vehicle can now be moved from the landing
location to continue work.

REAR OSCILLATION LOCK SYSTEM
The Rear Oscillation Lock System prevents the frame
from rotating on the rear axle.
System operation:
• With the boom below 20° elevation, the rear axle
oscillates freely.
DRIVE LOCKOUT OVERRIDE
Important: Read and understand the following
instructions BEFORE using the Drive
Lockout Override System!
Theory of Normal Operation
This vehicle is equipped with a stabilization system that
does several things to increase lateral (side-to-side)
stability.
When the boom is raised above 20° elevation:
• The transmission is limited to first and second
gears.
• The rear oscillation lock cylinder is limited to slow
(orificed) movement.
• The speed of the frame tilt function is limited.
When the boom is raised above 40° elevation:
• The rear axle stabilization cylinder is locked,
preventing the frame from rotating on the rear axle.
• The transmission is disengaged, stopping drive
capabilities.
• With the boom between 20° and 40° elevation:
Transmission is limited to first or second gear.
Rear axle is in “restricted oscillation” mode.
Frame tilt function still operates, but at a reduced
speed when the boom elevation is above 20°.
• With the boom above 40° elevation:
Transmission is locked out and rear axle oscillation
is locked to the frame.
Frame tilt function still operates, but at a reduced
speed.
• With the boom above 40° elevation and the drive
lockout override switch (page 14) pressed down:
Transmission is limited to first gear.
Rear axle is in “very restricted oscillation” mode.
• Fully pressing the brake pedal down locks the rear
axle at any boom angle.
W1052
Diagram 1: Stability Triangle (Front axle locked and
frame free to rotate on rear axle)
32
W1053
Diagram 2: Stability Rectangle (Front and rear
axles locked, preventing frame from rotating)
When the boom angle is below 20° the vehicle operates
with a freely oscillating rear axle to negotiate rough
terrain. (See Diagram 1)
Page 41
STABILITY SYSTEMS
When the boom angle is above 20° but below 40°, the
rear axle cylinder is orificed, slowing movement of the
frame on the rear axle. This increases the lateral (sideto-side) stability.
When the boom angle is above 40°, the rear axle
cylinder locks, preventing the frame rotating on the rear
axle. This changes the stability diagram from a triangle
to a rectangle (when viewed from above) and
substantially increases the vehicle’s lateral stability.
(See Diagram 2)
General Description, Drive
Lockout Override System
The Drive Lockout Override System does two things
when engaged with the boom angle above 40°:
• Allows the transmission to be engaged in first gear
only.
• Unlocks the rear oscillation lock cylinder and allows
very slow (orificed) movement. This increases
dynamic lateral stability while the vehicle is being
driven.
5. Drive the vehicle very slowly, while carefully
watching the terrain. Make turns smoothly and
slowly.
6. Use the service brakes to stop the vehicle slowly
and smoothly. Releasing the Drive Lockout
Override Foot Switch will disengage the drive,
but this will not activate the brakes.
WARNING
Operation of the Drive
Lockout Override System
To operate the Drive Lockout Override System:
WARNING
Failure to follow the instructions in this
manual may result in death or serious
personal injury!
Note: These procedures only apply to situations where
the boom is above 40° elevation.
1. Plan your route of travel. The surface must be
firm and as level as possible. Always avoid rough
or steep areas.
2. Level the frame before picking up the load. If load
is suspended (slung load), make sure tag lines
are secure and manned. Never let a slung load
sway, as this may lead to vehicle tipover or injury
to personnel.
3. With the brakes on, move the shift selector to the
Forward or Reverse position.
4. Using your left foot, press and hold down the
drive lockout override switch. The drive will
engage in first gear only and the vehicle may be
moved.

FUEL REQUIREMENTS
General
Diesel fuels are blended to meet the local temperature
requirements. The standard grades are:
1. 1D for temperatures -22 to +86 °F
(-30 to +30 °C).
2. 2D for temperatures +14 to +122 °F
(-10 to +50 °C)
There are two main classifications of diesel fuel in
general use:
1. Low-sulphur, “on-highway” diesel fuel.
2. Medium-sulfur, “off-highway” diesel fuel. This fuel
contains blue dye.
The engine manufacturer specifies the diesel fuel
requirements. Additional information can be found
below and in the engine manufacturer’s Operator’s
Manual.
Consult your local fuel distributor for the properties of
the diesel fuels available in your area.
John Deere Engines
Use of regular-sulfur “off-highway” diesel fuel is
recommended.
If low-sulfur “on-highway” diesel fuel is used, John
Deere Diesel Fuel Conditioner (TY22030) must be
added.
Use of low-sulfur fuel without the specified conditioner
may cause premature failure of the engine’s fuel system
components and void the warranty.
