The DISPLAY PANEL is a lighted text window that displays the present operating status or an existing error condition when the key switch is on.

When pushed in, the emergency STOP button disconnects electrical power to the ground and platform control stations. The emergency STOP pushbutton should only be pressed to immediately stop all boom motion. To resume control, pull out the emergency STOP button.
Boom Extend/Retract Buttons
Pressing and holding a desired SPEED button and the BOOM EXTEND button at the same time extends the telescopic boom. Pressing and holding a desired SPEED button and the BOOM RETRACT button at the same time retracts the boom. Boom motion continues until the buttons are released or until the boom reaches a hard stop or a safe travel limit.
Boom Raise/Down Buttons
Pressing and holding a desired SPEED button and the
LOWER BOOM RAISE or the UPPER BOOM RAISE button
at the same time will raise the selected boom. Pressing a desired SPEED button and the LOWER
BOOM DOWN or UPPER BOOM DOWN button at the same
time will lower the selected boom. Boom motion continues until the buttons are released or until each boom reaches a hard stop or a safe travel limit.
Jib Raise/Down Buttons
Pressing and holding a desired SPEED button and the JIB RAISE button at the same time will raise the jib boom. Pressing a desired SPEED button and the JIB DOWN button at the same time will lower the jib boom. Boom motion continues until the buttons are released or until the jib boom reaches a hard stop or a safe travel limit.
Boom Rotation CW/CCW Buttons
Pressing and holding a desired SPEED button and the BOOM ROTATION CW (clockwise) or CCW (counterclockwise) button at the same time enables the boom to rotate in the direction selected. The boom will rotate through 700 degrees until the buttons are released or the stop is reached.
Speed Buttons
The SPEED buttons along the lower right side of the control panel must be pressed and held while selecting a boom function. Four speeds are available to control the positioning of the boom lift.
Outrigger Controls
For automatic outrigger extension/retraction: Select EXTEND or RETRACT outrigger button and the AUTO LEVEL button at the same time. To manually extend or retract the outriggers: Select EXTEND or RETRACT outrigger button and one of the OUTRIGGER buttons at the same time. The outrigger indicator LEDs light up when the outriggers are properly deployed and the boom weight is on the outriggers. Each of the outer outrigger LEDs indicates load is on the outrigger footpad. Each of the inner outrigger LEDs, when flashing, indicate that side is low and needs to be further raised for leveling. The Auto Level LED lights up and a buzzer sounds when the boom is level.
Platform Tilt Buttons
Press and hold any SPEED button and the desired PLATFORM TILT button at the same time to level the work platform (levels the platform only, not the boom lift).
