mately seven seconds. Start the engine only after the light
goes out.

Indicates a fault with the engine and service is
required.
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 a JLG factory trained techni-
cian before the machine can be used.
