9. 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. The light flashes if the control
system puts the machine into creep speed and will be on
continuously if the operator selects creep speed.
10. System Distress Indicator
The light indicates that the JLG Control System has detected
a malfunction and a Diagnostic Trouble Code has been set in
the system memory. Refer to the Service Manual for instruc-
tions concerning the trouble codes and trouble code
retrieval.
The malfunction indicator light will illuminate for 2-3 sec-
onds when the key is positioned to the on position to act as
a self test.
11. Drive Orientation Indicator
When the boom is swung beyond the rear drive tires or fur-
ther 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).

12. Axles Set Indicator
Indicates that the axles are fully extended. The indicator will
flash as the axles are extending or retracting and be on solid
when fully extended. The light will go out when the axles are
fully retracted.
13. Boom Control System Warning Indicator
Indicates the platform is outside the operating area and
operation of certain boom functions may be disabled (i.e.
lift, telescope). Attempts to use the disabled functions cause
the indicator to flash and an alarm to sound. Immediately
return the platform to the ground. If the indicator remains lit,
a boom control system fault or failure has been detected. If a
failure is discovered, the system must be repaired by JLG
authorized service personnel before the machine can be
used.
