Machine Controls, Indicators, and Operation
Horn - This push-button switch, when activated, permits the operator to warn jobsite
personnel when the machine is operating in the area.
Joystick Controller with Trigger Enable Switch - The joystick controller controls four
functions: drive, lift, leveling jacks, and steer. The drive, lift, or leveling jacks function switch
must be selected and the trigger switch on the front of the control handle must be depressed
and held prior to moving the control handle and during controller movement.
After selecting the drive function, depressing the trigger switch and moving the control handle
forward will drive the machine forward and moving the control handle backwards will drive
the machine backward.
After selecting the lift function, depressing the trigger switch and moving the control handle
forward will lower the platform and moving the control handle backward will lift the platform
up.
After selecting the leveling jack function, depressing the trigger switch and moving the control
handle forward will extend all four leveling jacks. Moving the hand controller backward will
retract the leveling jacks.
The speed on all selected functions, except leveling jacks, is proportionally controlled by the
distance of travel of the hand controller.
Note: If the machine is also equipped with a footswitch (Korean Specification only),
the footswitch must be depressed in conjunction with the trigger (enable)
switch located on the controller. Power is removed from the platform controls
when the footswitch is released.
Leveling Jacks (If Equipped) - To engage Leveling Jacks, select the Lift function on the three-position switch.
Set and Retract LEDs will illuminate on the indicator pad when the control handle engages Set or Retract
functions.
Moving the control handle forward (black arrow direction) will lower the leveling jacks. Moving the control
handle backward (white arrow direction) will raise the leveling jacks. Once the machine is level the jacks will
discontinue extending and the jack LED will stop blinking and stay lit.
Leveling Jacks Set - This indicator light will blink when the leveling jacks are being
extended.
Leveling Jacks Retracting - This indicator light will blink when the leveling jacks are being
retracted.
