3-4 – JLG Lift – 3121618
ONLY USE THE PLATFORM LEVELING OVERRIDE FUNCTION FOR SLIGHT LEVELING OF
THE PLATFORM. INCORRECT USE COULD CAUSE THE LOAD/OCCUPANTS TO SHIFT OR
FALL. FAILURE TO DO SO COULD RESULT IN DEATH OR SERIOUS INJURY.
4. Platform Leveling Override
A three position switch allows
the operator to adjust the
automatic self leveling sys-
tem. This switch is used to
adjust platform level in situa-
tions such as ascending/
descending a grade.
5. Jib Lift
Provides raising and lowering of
the jib.
NOTE: Auxiliary power only works if there is no engine oil pressure, and
is disabled if engine is running.
Functions will operate at a slower than normal rate because of
the reduced hydraulic flow.
WHEN USING AUXILIARY POWER, DO NOT OPERATE MORE THAN ONE FUNCTION AT A
TIME. SIMULTANEOUS OPERATION CAN OVERLOAD THE AUXILIARY PUMP.
6. Engine Start/ Auxiliary Power Switch /Function Enable
To start the engine, the switch must be held
"UP" until the engine starts.
To use auxiliary power, the switch must be
held “DOWN” for duration of auxiliary pump
use.
When the engine is running, the switch must
be held "DOWN" to enable all boom controls.
WHEN THE MACHINE IS SHUT DOWN THE POWER/EMERGENCY STOP SWITCH MUST BE
POSITIONED TO THE OFF POSITION TO PREVENT DRAINING THE BATTERIES.
