22. 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, swing, and drive move-
ments.
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 auto-
matic position.
NOTE: Depending upon the angle of the chassis and the angle of
the boom, swing left or swing right may be disallowed
while in the Manual mode. The BCS light will illuminate
and further attempts to swing in the disallowed direction
will cause the BCS to flash. When this occurs the only
choices are to swing in the opposite direction or switch to
automatic mode.
