Page 57
2. Steer Select (If Equipped)
SECTION 3 - MACHINE CONTROLS AND INDICATORS
When equipped with four wheel steering, the
action of the steering system is operator
selectable. The center switch position gives
conventional front wheel steering with the rear wheels unaffected. This is for normal driving at maximum speeds. The
forward position is for “crab” steering. When in this mode
both front and rear axles steer in the same direction, which
allows the chassis to move sideways as it goes forward. This
can be used for positioning the machine in aisle ways or
against buildings. The back switch position is for “coordinated” steering. In this mode the front and rear axles steer in
the opposite directions to produce the tightest turning circle for maneuvering in confined areas.
To re-synchronize the front and rear axles, position the rear
drive wheels to the forward drive position by selecting
either crab or compound steer, then select front steer (center switch position) to operate the normal steering function.
ONLY USE THE PLATFORM LEVELING OVERRIDE FUNCTION FOR SLIGHT LEVELING OF
THE PLATFORM. INCORRECT USE COULD CAUSE THE LOAD/OCCUPANTS TO SHIFT OR
FALL. FAILURE TO DO SO COULD RESULT IN DEATH OR SERIOUS INJURY.

4.1DESCRIPTION
This machine is a self-propelled hydraulic personnel lift equipped
with a work platform on the end of an elevating and rotating
boom.
The primary operator control station is in the platform. From this
control station, the operator can drive and steer the machine in
both forward and reverse directions. The operator can raise or
lower the main or tower boom or swing the boom to the left or
right. Standard boom swing is 360 degree continuous left and
right of the stowed position. The machine has a Ground Control
Station which will override the Platform Control Station. Ground
Controls operate Boom Lift and Swing, and are to be used in an
emergency to lower the platform to the ground should the operator in the platform be unable to do so.
4.2OPERATING CHARACTERISTICS AND LIMITATIONS
Capacities
The boom can be raised above horizontal with or without any
load in platform, if:
1. Machine is positioned on a smooth, firm and level surface.
2. Load is within manufacturer’s rated capacity.
3. All machine systems are functioning properly.
4. Proper tire pressure.
5. Machine is as originally equipped from JLG.

SECTION 4 - MACHINE OPERATION
7. Push the Engine Start switch until engine starts.
NOTE:Footswitch must be in released (up) position before starter will
operate. If starter operates with footswitch in the depressed position, DO NOT OPERATE MACHINE.
Shutdown Procedure
IF AN ENGINE MALFUNCTION CAUSES AN UNSCHEDULED SHUTDOWN, DETERMINE
THE CAUSE AND CORRECT IT BEFORE RESTARTING THE ENGINE.
1. Remove all load and allow engine to operate at low speed
for 3-5 minutes; this allows further reduction of internal
engine temperature.
2. Push Power/Emergency Stop switch in.
3. Turn Platform/Ground Select switch to Off.
Refer to Engine Manufacturer’s manual for detailed
information.
Fuel Reserve / Shut-Off System
NOTE:Reference the Service and Maintenance Manual along with a
qualified JLG Mechanic to verify your machine setup.
The Fuel Shutoff System monitors the fuel in the tank and senses
when the fuel level is getting low. The JLG Control System automatically shuts the engine down before the fuel tank is emptied
unless the machine is set up for Engine Restart.
If fuel level reaches the Empty range, the Low Fuel
light will begin to flash once a second and there will
be approximately 60 minutes of engine run time
left. If the system is in this condition and automatically shuts down the engine or if the operator manually shuts down the engine before the 60 minute run time is
complete, the Low Fuel light will flash 10 times a second and the
engine will react according to machine setup. Setup options are
as follows:
• Engine One Restart - When the engine shuts down, the
operator will be permitted to cycle power and restart the
engine once with approximately 2 minutes of run time.
After the 2 minute run time is complete or if the engine is

for approximately 2 minutes of run time. After the 2 minutes of run time is complete, the operator may cycle power
and restart the engine for an additional 2 minutes of run
time. The operator can repeat this process until there is no
more fuel available.
CONTACT A QUALIFIED JLG MECHANIC IF THE MACHINE NEEDS RESTARTED AFTER NO
MORE FUEL IS AVAILABLE.
• Engine Stop - When the engine shuts down, no restarts
will be permitted until fuel is added to the tank.
4.4TRAVELING (DRIVING)
See Figure 4-3., Grade and Sideslope
NOTE:Refer to the Operating Specifications table for Gradeability and
Sideslope ratings.
All ratings for Gradeability and Sideslope are based upon the
machine’s boom being in the stowed position, fully lowered, and
retracted.
Traveling is limited by two factors:
1. Gradeability, which is the percent of grade of the incline the
machine can climb.
2. Sideslope, which is the angle of the slope the machine can
be driven across.

Traveling Forward and Reverse
DO NOT DRIVE WITH BOOM ABOVE HORIZONTAL EXCEPT ON A SMOOTH, FIRM AND
LEVEL SURFACE.
TO AVOID LOSS OF TRAVEL CONTROL OR “TIP OVER”, DO NOT DRIVE MACHINE ON
GRADES EXCEEDING THOSE SPECIFIED ON THE SERIAL NUMBER PLATE.
BE SURE THE TURNTABLE LOCK IS ENGAGED BEFORE ANY EXTENDED TRAVELING.
DO NOT DRIVE ON SIDESLOPES WHICH EXCEED 5 DEGREES.
USE EXTREME CAUTION WHEN DRIVING IN REVERSE AND AT ALL TIMES WHEN THE
PLATFORM IS ELEVATED.
BEFORE DRIVING, MAKE SURE BOOM IS POSITIONED OVER REAR DRIVE AXLE. IF
BOOM IS OVER FRONT WHEELS, STEER AND DRIVE CONTROLS WILL BE REVERSED.
1. At Platform Controls, pull out Emergency Stop
switch and activate footswitch.
2. Position Drive controller to FORWARD or
REVERSE as desired.
This machine is equipped with a Drive Orientation Indicator. The
yellow light on the platform control console indicates that the
boom is swung beyond the rear drive tires and the machine may
Drive/Steer in the opposite direction from the movement of the
controls. If the indicator is illuminated, operate the Drive function
in the following manner:

1. Match the black and
white direction arrows
on both platform control panel and the chassis to determine the
direction the machine
will travel.
2. Push and release the Drive Orientation Override switch. Within 3 seconds, slowly move the
Drive control toward the arrow matching the
intended direction of machine travel. The indicator light will flash during the 3 second interval until the drive function is selected.
Traveling on a Grade
When traveling a grade, maximum braking and traction are obtained
with the boom stowed, in position over the rear (drive) axle, and in
line with the direction of travel. Drive the machine forward when
climbing a grade, and in reverse when descending a grade. Do not
exceed the machine's maximum rated gradability.
IF THE BOOM IS OVER THE FRONT (STEER) AXLE, DIRECTION OF STEER AND DRIVE
MOVEMENT WILL BE OPPOSITE FROM THE MOVEMENT OF THE CONTROLS.

ated there is an interlock that prevents the use of Drive and Steer
functions.
Raising and Lowering the Tower Boom
This machine has two controls for the tower boom (two toggle
switches), one controls tower lift, the other tower telescope. The
switching system will sequence its Lift and Telescope functions as
follows:
1. Sequence while raising the Tower Boom from the fully lowered position.
a. The Tower Boom must be fully elevated “up”
(approximately 13 degrees from vertical)
before the Tower Boom can be extended
from the fully retracted position.
b. The Tower Telescope “out” or “in” will only
be operable when the Tower Boom is fully
elevated “up”.
2. Sequence while lowering the Tower Boom from the fully elevated “up” position.
a. Operate Tower Telescope “in” until Tower
Boom is fully retracted. (Tower must not lift
“down until boom is telescoped ”in” or “up”
fully.
