7. Platform Overload Indicator (If Equipped)
Indicates the platform has been overloaded.
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 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 personnel before the machine can be
used.
9. Boom Control System Calibrated Indicator
When the Boom Control System Test Button is pushed, illu-
minates to indicate that the Boom Control System is cali-
brated properly.

1. Power/Emergency Stop
A two-position red mushroom shaped switch furnishes
power to PLATFORM Controls when pulled out (on). When
pushed in (off ), power is shut off to the platform functions.
Within about 2 seconds of pulling the switch out, the
machine will perform a diagnostic check of the various elec-
trical circuits, and if everything is OK, the platform alarm will
beep once. During this time the lights on the indicator panel
will also blink once as a bulb check.
