6. Glow Plug/Wait to Start Indicator
Indicates the glow plugs are operating. After
turning on ignition, wait until light goes out
before cranking engine.
7. Low Fuel Indicator (Yellow)
Indicates the fuel tank is 1/8 full or less. When
the light first turns on, there are approximately
four usable gallons of fuel remaining.
8. 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.

10. 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).
11. Creep Speed Indicator
When the Function Speed Control is turned to
the creep position, the indicator acts as a
reminder that all functions are set to the slow-
est speed.
