NOTE: When Emergency Stop switch is in the “ON” position and
engine is not running, an alarm will sound, indicating Igni-
tion 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.
8. 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.
NOTE: Auxiliary power only works if there is no engine oil pres-
sure, and is disabled if engine is running.
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.

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.
The enable switch must be held "DOWN" to
enable all boom controls when the engine is
running.
