8. System Distress Indicator
The light indicates that the JLG Control System has
detected an abnormal condition and a Diagnostic Trou-
ble Code has been set in the system memory. Refer to
the Service Manual for instructions concerning the trou-
ble 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).
