3.5.1 Platform Control Station Functions
To avoid serious injury, do not operate machine if any control levers or toggle
switches controlling platform movement do not return to the off or neutral position
when released.
Only use the platform leveling override function for slight leveling of the platform.
Incorrect use could cause the load/occupants to shift or fall. Failure to do so could
result in death or serious injury.
Auxiliary Descent Enable
To use auxiliary descent enable, the switch must be held down for the dura-
tion of function use.
Drive Orientation Override
When the boom is swung over the rear tires or further in either direction, the
Drive Orientation indicator will illuminate when the drive function is se-
lected. Push and release the switch, and within 3 seconds move the Drive/
Steer control to activate drive or steer. Before driving, locate the black/ white
orientation arrows on both the chassis and the platform controls and match
the control direction arrow to the intended direction of travel.
Note: To operate the Drive joystick, pull up on the locking ring below the handle.
Note: The Drive joystick is spring loaded and will automatically return to neutral (Off) position
when released.
Drive / Steer
Push forward to drive forward, pull back to drive in reverse. Steering is ac-
complished via a thumb-activated rocker switch on the end of the Drive
joystick.
