8. Platform Overload Indicator (If Equipped)
Indicates the platform has been over-
loaded.
9. 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.
10. Boom Control System Calibrated Indicator
When the Boom Control System Test But-
ton is pushed, illuminates to indicate that
the Boom Control System is calibrated
properly.
