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 con-
cerning 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.
Cable Service Indicator
When illuminated, the light indicates the
boom cables are loose or broken and
must be repaired or adjusted immedi-
ately.
12.
Drive Orientation Indicator
When the boom is swung beyond the rear
drive tires or further in either direction,
the Drive Orientation indicator will illumi-
nate 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 direc-
tion (i.e. controls reversed situations).
13.
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.
14.
Boom Control System Warning Indicator
Indicates the platform is outside the oper-
ating area and operation of certain boom
functions may be disabled (i.e. lift, tele-
scope). 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 per-
sonnel before the machine can be used.
