8. Engine Start/Auxiliary Power Switch
or
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. Aux power can only be used if the
engine is not running.
If equipped, the enable switch must be held
"DOWN" to enable all boom controls when
the engine is running.
NOTE: Auxiliary power only works if there is no engine oil pres-
sure, and is disabled if engine is running.
NOTE: Functions will operate at a slower than normal rate
because of the lesser flow of hydraulic fluid delivered.
WHEN USING AUXILIARY POWER, DO NOT OPERATE MORE THAN ONE
FUNCTION AT A TIME. (SIMULTANEOUS OPERATION CAN OVERLOAD
THE AUXILIARY PUMP.)
9. Articulating Jib Boom. (If Equipped)
This switch provides raising and lowering of the jib.
10. Platform Leveling Override.
A three position switch allows the operator to compen-
sate for any difference in the automatic self leveling sys-
tem.
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.
11. 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.
