Equipment and instrument
The installed equipment and shapes differ on the engine type.
Start and stop instrument
Start switch
When the start switch on the operation panel is
pressed, starting system is operated and cranks the
engine.
Stop switch
When the stop switch on the operation panel is
pressed, the stop solenoid operates and moves the
control shaft of the fuel injection pump to the no-injec-
tion position to shut down the engine operation.
Fig. 2-3 Start switch and stop switch
Manual stop lever
Use the manual stop lever to shut down the engine in
the event of an emergency. If the stop switch fails to
stop engine operation, use the manual stop lever.
When the manual stop lever, which is located in the
fuel control link, is moved in the [STOP] direction, the
engine stops.
If the engine continues to operate even after the man-
ual stop lever is moved in the STOP position, cut off
the fuel supply to stop the engine.

Stop solenoid
The stop solenoid operates for normal shutdown of
engine operation. The stop solenoid moves the rack of
fuel injection pump to cut the fuel, and consequently
stops the engine. Two types of stop solenoids are
available.
RUN OFF type
Not energized while the engine is running. Energized
by a stop signal to stop the engine.
RUN ON type
Energized while the engine is running, and de-ener-
gized to stop the engine.
