SECTION 3 - USER RESPONSIBILITIES AND MACHINE CONTROL
3120854 – JLG Lift – 3-3
1. Power Selector Switch
A three position, key-operated power selector switch
supplies operating power to the platform or ground
controls, as selected. When positioned to platform,
the switch provides power to the emergency stop
switch at the platform controls. When positioned to
ground, the switch provides power to the emer-
gency stop switch at the ground controls. With the
power selector switch in the center off position,
power is shut off to both platform and ground con-
trols.
NOTE: With the power selector switch in the off position, the
key can be removed in order to avoid unauthorized
use of the machine.
Low speed is the default speed for all functions when
the platform is fully lowered. When the platform is
elevated, all functions operate in creep speed only.
2. Emergency Stop Switch
A two-position, red, mushroom-shaped emergency
stop switch, when positioned to on (pulled out) with
the power selector switch positioned to ground, fur-
nishes operating power to the ground control sta-
tion. In addition, the switch can be used to turn off
power to the function controls in the event of an
emergency. Power is turned on by pulling the switch
out (on), and is turned off by pushing the switch in
(off).
3. Lift Switch
A three-position, momentary-contact switch pro-
vides raising and lowering of the platform when
positioned to up or down.
4. Circuit Breaker
A push button reset 15 Amp circuit breaker, located
behind the pump/motor in the left side door, returns
interrupted power to the machine functions when
depressed.
5. Hourmeter
The machine may be equipped with an hourmeter to
indicate the number of hours the machine has been
operated. The hourmeter operates when a machine
function is operating or when key switch and emer-
gency stop switch are on.
Platform Control Station
1. Emergency Stop Switch
A two-position, red, mushroom-shaped emergency
stop switch functions to provide power to the plat-
form control station and also to turn off power to the
platform function controls in the event of an emer-
gency. With the power selector switch positioned to
platform, power is turned on by pulling the switch
out (on), and is turned off by pushing the switch in
(off).
2. Enable Switch
The enable switch is located on the left side
of the platform control box. This switch must be
depressed and held before and during actuation of
the lift function and for the duration of lift. The enable
switch works in conjunction with the lift switch.
3. Drive
The joystick is used to drive the machine forward
and reverse. To drive, the red trigger on the front of
the joystick must be depressed and held. Then the
joystick must be pushed forward for forward travel or
pulled backward for reverse travel. The adjustment
between low and high speed is determined by the
joystick travel. When motor is first activated you are
in low speed, high speed is achieved by moving the
joystick to the complete forward position.
NOTE: When the machine is raised, and a door is opened,
the machine will not drive.
The drive system may make an occasional cavitation
noise when driving with steer wheels turned all the
way in one direction or while going down hill. This
noise is a byproduct of the drive system.
4. Lift
The lift switch, when used in conjunction with the
enable switch, will raise or lower the machine. Lift is
activated by pressing and holding the enable and
moving the lift switch forward (lift up) or backward
(lift down).
DO NOT “LIFT DOWN” WITHOUT COMPLETELY RETRACTING
THE PLATFORM EXTENSION.
5. Steer Switch
The thumb-operated steer switch, located on top of
the joystick controller, activates the steer wheels in
the direction the switch is moved (left or right).
DO NOT USE HIGH DRIVE SPEED WHEN DRIVING IN CLOSE
QUARTERS OR WHEN DRIVING IN REVERSE.
6. Drive Speed Select Switch
The speed select switch is a toggle switch which
allows you to select high or low speed.
NOTE: The High Drive Speed switch will cut-out when the
platform is raised above the stowed position, return-
ing drive speed to low until the platform is lowered
completely.
