Operating the Machine
AUTO-IDLE SWITCH
The auto-idle circuit automatically reduces engine speed
after 4 seconds when control levers are placed in neutral
position. Press switch (A) to turn circuit ON.
CAUTION: Turn auto-idle switch OFF when
automatic acceleration of engine speed is not
desired, and when stopping engine.
Always check auto-idle switch before operating
any control levers. When ON, the engine speed
lowers to auto-idle speed (regardless of the
position of the engine speed control lever)
approximately 4 seconds after the control
levers are returned to neutral. By operating the
control levers, the engine speed increases to
the engine rpm dial setting.
Starting engine when auto-idle is ON:
1. When key switch is turned ON, buzzer will sound
briefly.
2. The engine will run at the engine rpm dial setting for 4
seconds after turning the key switch ON. The auto-idle
system will then slow the engine to auto-idle engine
speed.
3. Engine speed increases to engine rpm dial setting
when any control lever is operated.
4. Four seconds after control levers are returned to
neutral, the engine speed is reduced automatically to
auto-idle level. Engine will run at auto-idle speed if
engine is started more than 4 seconds after turning key
switch ON.
When the auto-idle switch is turned OFF, the engine
speed is controlled by the engine rpm dial.
Indicator (B) will light when auto-idle is ON.
Turn auto-idle switch OFF and set engine rpm dial to
improve machine control in difficult work areas,
loading, and unloading.
