4. Engine Oil Temperature Indicator
Indicates the temperature of the engine oil, which also
serves as engine coolant, is abnormally high and ser-
vice is required.
5. Glow Plug Indicator
Indicates the glow plugs are operating. After turning on
ignition, wait until light goes out before cranking engine.
6. 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.
7. Platform Capacity Indicator
Indicates platform capacity. On 1100SJP models, this
capacity can be selected at the platform control con-
sole.
8. 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.
9. Boom Control System Test Indicator
When the Boom Control System Test Button is pushed,
illuminates to indicate that the Boom Control System is
calibrated properly. See “Boom Control System Check
Procedure” on page 2-6.
