SECTION 4. MACHINE OPERATION
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 boom or swing the boom to the left
or right. Standard boom swing is 355 degree non-continuous. 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.

SECTION 4 - MACHINE OPERATION
See Figure 4-3., Grade and Side Slopes
NOTE: Refer to the Operating Specifications table for Gradeabil-
ity 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.
DO NOT DRIVE WITH BOOM OUT OF TRANSPORT MODE 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 IN THE OPERATING SPECIFICATIONS SECTION OF THIS MANUAL.

6.4TIRES & WHEELS
Tire Replacement
JLG recommends a replacement tire be the same size, ply and
brand as originally installed on the machine. Please refer to the
JLG Parts Manual for the part number of the approved tires for a
particular machine model. If not using a JLG approved replacement tire, we recommend that replacement tires have the following characteristics:
• Equal or greater ply/load rating and size of original
• Tire tread contact width equal or greater than original
• Wheel diameter, width, and offset dimensions equal to
the original
• Approved for the application by the tire manufacturer
(including inflation pressure and maximum tire load)
Unless specifically approved by JLG Industries Inc. do not
replace a foam filled or ballast filled tire assembly with a pneumatic tire. When selecting and installing a replacement tire,
ensure that all tires are inflated to the pressure recommended
by JLG. Due to size variations between tire brands, both tires
on the same axle should be the same.
Wheel and Tire Replacement
The rims installed on each product model have been designed
for stability requirements which consist of track width, tire pressure, and load capacity. Size changes such as rim width, center
piece location, larger or smaller diameter, etc., without written
factory recommendations, may result in an unsafe condition
regarding stability.
Wheel Installation
It is extremely important to apply and maintain proper wheel
mounting torque.
WHEEL NUTS MUST BE INSTALLED AND MAINTAINED AT THE PROPER
TORQUE TO PREVENT LOOSE WHEELS, BROKEN STUDS, AND POSSIBLE DANGEROUS SEPARATION OF WHEEL FROM THE AXLE. BE SURE
TO USE ONLY THE NUTS MATCHED TO THE CONE ANGLE OF THE
WHEEL.
Tighten the lug nuts to the proper torque to prevent wheels from
coming loose. Use a torque wrench to tighten the fasteners. If
you do not have a torque wrench, tighten the fasteners with a
lug wrench, then immediately have a service garage or dealer
tighten the lug nuts to the proper torque. Over-tightening will
result in breaking the studs or permanently deforming the

mounting stud holes in the wheels. The proper procedure for
attaching wheels is as follows:
1. Start all nuts by hand to prevent cross threading. DO
NOT use a lubricant on threads or nuts.
2. Tighten nuts in the following sequence.
3. The tightening of the nuts should be done in stages. Fol-
lowing the recommended sequence, tighten nuts per
wheel torque.
4. Wheel nuts should be torqued before first road use and
after each wheel removal. Check and torque every 3
months or 150 hours of operation.
