3. Glow Plug/Wait to Start Indicator
Indicates the glow plugs are operating.
After turning on ignition, wait until light goes
out before cranking engine.
4. Footswitch/Enable Indicator
To operate any function, the footswitch
must be depressed and the function
selected within seven seconds. The enable
indicator shows that the controls are enabled. If a func-
tion is not selected within seven seconds, or if a seven
second lapse between ending one function and begin-
ning the next function, the enable light will go out and
the footswitch must be released and depressed again to
enable the controls.
Releasing the footswitch removes power from all con-
trols and applies the drive brakes.
TO AVOID SERIOUS INJURY, DO NOT REMOVE, MODIFY OR DISABLE
THE FOOTSWITCH BY BLOCKING OR ANY OTHER MEANS.
FOOTSWITCH MUST BE ADJUSTED IF FUNCTIONS ACTIVATE WHEN
SWITCH ONLY OPERATES WITHIN LAST 1/4" OF TRAVEL, TOP OR BOT-
TOM.
5. 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
slowest speed.
6. 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.
