SECTION 3 - MACHINE CONTROLS AND INDICATORS
3121255 – JLG Lift – 3-21
9. 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 instructions 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.
10. Cable Service Indicator
When illuminated, the light indicates the boom cables
are loose or broken and must be repaired or adjusted
immediately.
11. 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).
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 func-
tions cause the indicator to flash and an alarm to sound.
Immediately return the platform to the ground. If the indi-
cator 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.
