8. System Distress Indicator
The light indicates that the JLG Control
System has detected an abnormal condi-
tion 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 oper-
ated in the proper direction (i.e. controls reversed situa-
tions).
