SECTION 3 - MACHINE CONTROLS AND INDICATORS
3-2 – JLG Lift – 3121204
Ground Controls
(See Figure 3-1., Ground Control Station)
NOTE: If equipped, the Function Enable switch must
be held down in order to operate Main Boom
Telescope, Tower Lift, Swing, Main Lift, Jib
Lift, Platform Level Override, and Platform Rotate func-
tions.
1. Platform Rotate
A three position switch permits rotation of the platform.
ONLY USE THE PLATFORM LEVELING OVERRIDE FUNCTION FOR
SLIGHT LEVELING OF THE PLATFORM. INCORRECT USE COULD
CAUSE THE LOAD/OCCUPANT TO SHIFT OR FALL. FAILURE TO DO SO
COULD RESULT IN DEATH OR SERIOUS INJURY.
2. Platform Leveling Override
A three position switch allows the operator to compen-
sate for any difference in the automatic self leveling sys-
tem.
3. Jib (If Equipped)
This switch provides raising and lowering of the jib.
NOTE: When Power/Emergency Stop switch is in the “ON” posi-
tion and engine is not running, an alarm will sound, indi-
cating Ignition is “ON”.
WHEN THE MACHINE IS SHUT DOWN THE MASTER/EMERGENCY STOP
SWITCH MUST BE POSITIONED TO THE “OFF” POSITION TO PREVENT
DRAINING THE BATTERY.
NOTE: On machines with diesel engines, when Glow Plug Indi-
cator is lighted (Yellow), wait until light goes out before
cranking engine.
4. Power/Emergency Stop Switch
Pull out ON-OFF POWER/EMERGENCY STOP SWITCH
to turn on engine ignition and power to the electrical
system. Push in to shut off engine and remove power
from the controls. The Ground Control Emergency Stop
Switch must be pulled out to operate the machine from
either Ground Control or Platform Control. This allows
the machine to be shut down in emergency situations by
those untrained in the operation of the lift but who rec-
ognize the Emergency Stop Switch. The keyed Master
Switch can also be used for the same purpose.
