Machine Controls and Indicators
Capacity Select
This switch allows the operator to select between an operating envelope with a 500 lb (227 kg for
ANSI markets and 230 kg for CE and Australia markets) capacity restriction or a 1000 lb (454 kg for
ANSI markets and 450 kg for CE and Australia markets) capacity restriction.
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 selected. 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. Move the drive controls in a
direction matching the directional arrows for the intended direction of travel.
Note: Lift, Swing, and Drive control levers are spring-loaded and will automatically return to
neutral (off) position when released.
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.
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 Speed / Torque Select
The machine has a three position switch.
The forward position gives maximum drive speed. The center position allows the machine to be
driven as quietly as possible. The back position gives maximum torque for rough terrain and climbing
grades.
Do not operate machine if drive speed /torque select switch operates when boom is above horizontal.
Drive / Steer
Push forward to drive forward, pull back to drive in reverse. Steering is accomplished via a thumb-
activated rocker switch on the end of the steer handle.
Engine Start / Auxiliary Power
When pushed forward, the switch energizes the starter motor to start the engine.
The Auxiliary Power control switch energizes the electrically operated hydraulic pump. (Switch must
be held on for duration of auxiliary pump use.)
