Machine Controls and Indicators
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.
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.
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.)
The auxiliary pump functions to provide sufficient oil flow to operate the basic machine functions
should the main pump or engine fail. The auxiliary pump will operate tower boom lift, tower
telescope, main boom lift, main telescope and swing.
Function Speed Control
This control affects the speed of the Main Boom Telescope, Tower Boom Lift, Jib Lift, Jib Swing, and
Platform Rotate functions.
Note: During platform rotation, a speed difference may not be noticeable to the operator.
Turning the knob all the way counterclockwise until it clicks puts the machine into Creep Mode.
Creep Mode puts the functions listed above, as well as the Drive/Steer and Main Lift/Swing functions
into the slowest speed setting.
Do not operate machine if function speed switch operates when boom is above
horizontal.
Horn
A push-type Horn switch supplies electrical power to an audible warning device when pressed.
