Boom Control System Warning

If operating a function causes the Boom Control System Warning Light to flash and the platform
!
alarm to sound, the selected movement is not allowed. To continue movement, operate the
function in the opposite direction or operate a different function.

Creep Speed

The creep light acts as a reminder that all functions are set to the slowest speed. The light will be
on continuously if the creep switch is selected by the operator. The creep light will flash if the JLG
control system has selected this creep speed automatically. This occurs when the boom is near the
edge of the envelope or the Boom Control System Warning is active.

Footswitch/Enable

To enable the platform controls, step on the footswitch FIRST and then choose a function within
7 seconds. If no function is selected within 7 seconds, the Footswitch/Enable light will turn off and
the footswitch must be released and depressed again.
When the Platform Capacity is selected to the 500 lb (230 kg) position, the 500 lb
(230 kg) light will be on and the JLG control system will allow operation within the larger
envelope. The side swing jib can be used with this selection.
When the Platform Capacity is properly selected to the 1000 lb (450 kg) position, the
1000 lb (450 kg) light will be on, and the JLG control system will allow operation within
the smaller envelope. The side swing jib must remain in the centered position with
this selection.
Note: If both capacity lights are flashing, the boom or jib is out of the allowable
envelope. Remove platform load over 500 lb (230kg) and select the 500 lb
(230kg) capacity position.
Automatic
Note: When selected to the Automatic position, the coordination of boom movements
within the envelope is as follows:
• While operating Lift Up, the boom may also telescope out
• While operating Lift Down, the boom may also telescope in
• While operating Swing or Drive, the boom may lift up or lift down
• While operating Telescope In, the boom may lift down when at
high boom angles and the creep light is flashing
Manual
Note: When selected to the Manual position, the boom movements will be stopped
when the envelope limits are reached. If this occurs, operate the function in the
opposite direction, operate a different function, or select the Automatic position.
WARNING!
