ONLY USE THE PLATFORM LEVELING OVERRIDE FUNCTION FOR
SLIGHT LEVELING OF THE PLATFORM. INCORRECT USE COULD CAUSE
THE LOAD/OCCUPANT TO SHIFT OR FALL. FAILURE TO DO SO COULD
RESULT IN DEATH OR SERIOUS INJURY.

2. Platform Leveling Override

A three position switch allows the operator to adjust the
automatic self leveling system. This switch is used to
adjust platform level in situations such as ascending/
descending a grade.

3. Jib (If Equipped)

The jib control switch provides raising and lowering of
the jib when positioned to UP or DOWN.

NOTE: When Power/Emergency Stop switch is in the “ON” posi-

tion and engine is not running, an alarm will sound, indi-
cating Ignition is “ON”.

WHEN THE MACHINE IS SHUT DOWN THE MASTER/EMERGENCY STOP
SWITCH MUST BE POSITIONED TO THE “OFF” POSITION TO PREVENT
DRAINING THE BATTERY.

4. Power/Emergency Stop Switch

A two-position red mushroom shaped switch furnishes
power to PLATFORM/GROUND SELECT switch when
pulled out (on). When pushed in (off), power is shut off
to the PLATFORM/GROUND SELECT switch.
