Auxilary Power
While operating tower lift, the JLG control system will also coordinate the movement of the main
boom within its allowable limits. While operating tower lift up, the main boom will also lift up.
While operating tower lift down, the main boom will also lift down. The main boom can also be
positioned manually using the main lift controller.
Lift and telescope movements of the tower boom are coordinated by the JLG control system.
While operating tower lift up, the tower boom will also telescope out. While operating tower lift down,
the tower boom will also telescope in.
Platform leveling is controlled by the JLG control system to maintain a set platform position.
This feature is active during and drive movements. The starting platform position canlift, swing,
be manually adjusted using the platform level override switch.
Note: Movements of the boom using auxiliary power will be SLOW and the movements
will momentarily stop and alternate between other functions as needed. When operating
Tower Lift, the movements will alternate between tower lift, tower telescope, and main
lift. When operating Main Lift, the movements will alternate between main lift, tower lift,
and platform level.
To operate a function using Auxiliary power, operate the function while activating the auxiliary
power switch.
Boom Control System Warning
