3.5.1 Platform Control Station Functions
To avoid serious injury, do not operate machine if any control levers or toggle
switches controlling platform movement do not return to the off or neutral position
when released.
Only use the platform leveling override function for slight leveling of the platform.
Incorrect use could cause the load/occupants to shift or fall. Failure to do so could
result in death or serious injury.
Axle Extend / Retract
Allows the operator to extend or retract the axles. The axles can only be extended or retracted while
the machine is being driven forward or reverse.
Boom Control Select
Automatic Mode:
When the Boom Control is positioned to Automatic, lift and telescope movements are coordinated by
the JLG control system and the automatic platform leveling feature is active during lift, telescope,
and drive movements.
Note: •
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 Mode:
When the boom control is positioned to Manual, lift and telescope movements are controlled
separately by the operator and the automatic platform leveling feature is active only during lift
functions.
Note: When positioned to Manual, boom functions will be stopped when the envelope limits are
reached. When this occurs, operate a different function or select the automatic position.
Note: Depending upon the angle of the chassis and the angle of the boom, swing left or swing
right may not be allowed while in the Manual mode. The BCS light will illuminate and fur-
ther attempts to swing in the not allowed direction will cause the BCS to flash. When this oc-
curs the only choices are to swing in the opposite direction or switch to Automatic mode.
