Jib
If operating drive and the Drive Orientation Light flashes, the drive controls may be opposite from the
movement of the controls. To continue: 1) verify the intended drive direction, 2) push and release
the Drive Orientation Override switch, and 3) operate drive within 3 seconds.
Axles must be extended and the Axle Set light must be on to elevate the boom. To extend the axles,
use the Axle Extend switch while driving forward or reverse.
Jib must be deployed and the Jib Lock Pin must be engaged to elevate the boom. To
actuate the jib, use the Jib Stow switch.
The Platform Capacity must be set to 500 lb (227 kg) in order to operate the jib.
When Capacity Select is in the 500 lb(227 kg) position, the 500 lb(227 kg) light will be on
and the JLG control system will allow operation within the unrestricted envelope.
Note: If both capacity lights are flashing, the boom or jib is out of the allowable envelope.
Remove platform load over 500 lb(227 kg) and select the 500 lb(227 kg) capacity position.
When Capacity Select is in the 1000 lb (454 kg) position, the 1000 lb (454 kg) light will be
on, and the JLG control system will allow operation within the restricted envelope.
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.
Boom Control Select
When Boom Control Select is in the Automatic position, lift and telescope movements are
coordinated by the JLG Control System and the automatic platform leveling feature is active during
lift, swing, and drive movements.
• 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
When Boom Control Select is in the Manual position, lift and telescope movements are controlled
separately by the operator and the automatic platform leveling feature is active only
during lift movements.
Note: When in 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.
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.
WARNING!
The Boom Control System Warning Light may indicate contact
of the machine with another structure and continued movement
may result in damage to the machine or machine tip over.
!
Creep Speed
The Creep Speed 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 creep speed automatically. This occurs when the boom is
near the edge of the envelope or the Boom Control System Warning is active.

envelope is as follows:
