SECTION 4. MACHINE OPERATION
4.1 DESCRIPTION
This machine is a self-propelled hydraulic lift equipped
with a work platform on the end of an elevating, articulat-
ing and rotating boom. The JLG Lift’s intended purpose is
to position personnel with their tools and supplies at posi-
tions above ground level, and can be used to reach work
areas located above machinery or equipment.
The JLG Lift has a primary operator Control Station in the
platform. From this control station, the operator can drive
and steer the machine in both forward and reverse direc-
tions. The operator can raise or lower the upper or lower
boom or swing the boom to the left or right. Standard
boom swing is 360 degree non-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 Upper and Lower 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. Ground Control also to be used in
Pre-Operation check.
Instructions and hazard alerts are posted on the operator
control stations and at other places on the machine. It is
extremely important that operators know what instructions
and hazard alerts are placed on the machine, and review
these periodically so that they are fresh in their minds.
Vibrations emitted by these machines are not hazardous
to an operator in the work platform.
The JLG Lift is designed to provide efficient and safe oper-
ation when maintained and operated in accordance with
warnings on the machine, in the Operators & Safety Man-
ual, and all jobsite and government rules and regulations.
As with any type of machinery, the operator is very impor-
tant to efficient and safe operation. It is absolutely neces-
sa r y th a t th e J LG L i ft be r e g u l a r l y m ai n ta i n e d i n
accordance with this section and the Preparation and
Inspection section, and that any evidence of lack of main-
tenance, malfunction, excessive wear, damage or modifi-
cation to the machine be reported immediately to the
machine owner or the jobsite supervisor or safety man-
ager and that the machine be taken out of service until all
discrepancies are corrected.
The JLG Lift is not intended to be used to lift material other
than supplies which personnel in the platform require to
do their job. Supplies or tools which extend outside the
platform are prohibited. It must not be used as a forklift,
crane, support for overhead structure, or to push or pull
another object.
The JLG Lift is powered using a hydraulic pump and cylin-
ders for various functions. The hydraulic components are
controlled by electrically activated hydraulic valves using
switches and control levers. The speeds of boom func-
tions are variable from zero to maximum speed depend-
ing upon the position of the function speed control.
Functions controlled by toggle switches are either on or
off. A foot operated switch in the platform must be
depressed before any controls will function and provides
a means of emergency stop when the operators foot is
removed from the footswitch.
The JLG Lift is a two wheel drive machine with drive power
being supplied by 2 electric motors thru planetary gear
reducers.
The unrestricted capacity of the JLG Lift is 230 kg. This
means that with a platform load of 230 kg. or less, the plat-
form may be positioned anywhere the boom will reach,
with the machine on a smooth, firm, and level surface.
4.2 GENERAL
This section provides the necessary information needed
to operate the machine. Included in this section are proce-
dures for traveling, steering, parking, platform loading and
transporting. It is important that the user read and under-
stand the proper procedures before operating the
machine.
4.3 MOTOR OPERATION
Power/Emergency Stop
This red, mushroom-shaped switch provides battery
power to the Platform/Ground Select switch, when pulled
out (on), for all machine functions. The switch should be
pushed in (off) when recharging the batteries or parking
the machine overnight.
NOTE: If equipped with the optional on-board generator, the
Emergency Stop switch must be left on (pulled out)
to allow for automatic charging of the batteries.
Within about 2 seconds of pulling the switch out, the
machine will perform a diagnostic check of the various
electrical circuits, and if everything is OK, the platform
alarm will beep once. During this time the lights on the
indicator panel will also blink once as a bulb check.
