Machine Controls and Indicators
Function Speed Control
This control knob affects the speed of the Tower Lift, Tower Telescope, Jib Lift, Telescope, 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.
Note: To operate the Main Boom Lift/Swing joystick, pull up on the locking ring below the handle.
Note: The Main Boom Lift/Swing joystick is spring loaded and will automatically return to neutral
(Off) position when released.
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.
Jib
Push forward to lift up, pull back to lift down. Variable lift speed is using the Function Speed Control.
Lights (If Equipped)
This switch operates the accessory lights package if the machine is so equipped.
Note: The ignition switch does not have to be on to operate the lights, so care must be taken to
avoid draining the battery if left unattended. The master switch and/or the ignition switch at
the ground control will turn off power to all lights.
Main Boom Telescope
Provides extension and retraction of the main boom.
