SECTION 3 - USER RESPONSIBILITIES AND MACHINE CONTROL
3121110 – JLG Lift – 3-5
3.5 PLATFORM CONTROL STATION
CONTROL BOXES SHOULD NOT BE SWITCHED FROM ONE
MACHINE TO ANOTHER.
1. Emergency Stop Switch - A two-position, red, mush-
room-shaped emergency stop switch functions to
provide power to the platform control station and
also to turn off power to the platform function con-
trols in the event of an emergency. 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. Controller (Joystick) - The Joystick controls three
functions: drive, steer, drive/lift speed and optional
outriggers. The drive or the lift function switch must
be selected prior to moving the machine with the
Joystick. The speed is controlled by the travel dis-
tance of the Joystick. The thumb-operated steer
switch on top of the Joystick handle activates the
steer wheels in the direction it is moved (right or left).
3. Speed/Generator Switch - The three position speed/
generator switch permits the operator to select
either high range, low range or the generator (if
equipped).
NOTE: The machine cannot be lifted up from platform con-
trols or driven when the generator is selected.
4 wheel drive is operational in low drive only.
DO NOT USE HIGH RANGE WHEN DRIVING IN CLOSE QUARTERS
OR WHEN DRIVING IN REVERSE.
NOTE: The Low/High 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.
4. Drive Select Switch - When selected, the drive func-
tion will be active for 3 seconds. Moving the control-
ler in the forward or reverse direction within the 3
seconds will cause drive motion to occur at a speed
determined by the range selected by the Low/High
switch and the distance the controller is move from
center.
5. Lift Switch - When selected, the lift function will be
active for 3 seconds. Moving the controller in the for-
ward or reverse direction within the 3 seconds will
cause lift motion to occur at a speed determined by
the range selected by the Low/High switch and the
distance the controller is moved from center.
6. Leveling Jacks (Optional) - When selected, the level-
ing Jack function will be active for 3 seconds. Mov-
ing the controller in the forward or reverse direction
within the 3 seconds will cause drive motion to occur
at a speed determined by the range selected by the
Low/High switch and the distance the controller is
moved from center. Indicator lights will illuminate
stating leveling jacks being set or retracted. See Fig-
ure 3-3., Indicator Panel
NO FUNCTIONS WILL OPERATE IF THE LEVELING JACKS ARE
NOT EITHER FULLY EXTENDED OR FULLY STOWED.
DO NOT “LIFT DOWN” WITHOUT COMPLETELY RETRACTING
THE PLATFORM EXTENSION.
7. Engine/Filter Distress Light - This warning light,
when illuminated, warns the operator of an engine or
hydraulic system fault condition. A bank of warning
lights, located at the ground control station, indi-
cates the specific fault condition to the operator. The
indicator lights are: Alternator, Charge Pressure,
Engine Temperature, Oil Pressure, and Return Filter.
8. Horn - This push-button switch, when activated, per-
mits the operator to warn jobsite personnel when the
machine is operating in the area.
