Key Position and Device Operation
ON (Run)
The diesel engine on the machine runs or
stops based on the fuel supply.
When the key is set to the "OFF" position,
the engine stop solenoid is turned off, and
fuel is shut off.
After the engine starts, while the key remains
in the "ON" position, the solenoid works and
fuel is supplied. (This type of solenoid is
always conductive. During operation =
conductive.)

Glow (Thermo-Start)
When the ignition key is kept in the "GLOW"
position, the glow plug is generating heat
and the thermo-start lamp is turned on.
The lamp turns off at the specified time.
However, the lamp turning off is not related
to the glow plug generating heat, and the
plug is kept heated as long as the key is in
"GLOW" position even after the lamp is
turned off.
The glow lamp will stay illuminated for five
seconds.
The glow plug is located at engine head of
each cylinder and is connected by the plate.

The electrical circuit of the starter motor is
such that it does not turn unless the engine
activation conditions of the interlock system
are satisfied.
