System Distress Indicator

The light indicates that the JLG Control System
has detected an abnormal condition and a
Diagnostic Trouble Code has been set in the
system memory. Refer to the Service Manual for instructions
concerning the trouble codes and trouble code retrieval.

9.

Drive Orientation Indicator

When the boom is swung beyond the rear
drive tires or further in either direction, the
Drive Orientation indicator will illuminate
when the drive function is selected. This is a signal for the
operator to verify that the drive control is being operated in
the proper direction (i.e. controls reversed situations).
