Equipment and Instrument
Starting and Shutdown Devices
The shape and type of the starting and shutdown devices may vary from those described below depending on
the engine specifications.
Start Switch
When the start switch on the operation panel is
pressed, starting air is supplied to the air starter sys-
tem and cranks the engine.
Stop Switch
When the stop switch on the operation panel is
pressed, the shutdown cylinder operates and moves
the control shaft of the fuel injection pump to the no-
injection position to shut down the engine operation.
Manual stop lever
Use the manual stop lever to shut down the engine
in the event of an emergency.
If the starter switch fails to stop engine operation,
use the manual stop lever.
When the lever is moved in the [STOP] direction, the
engine stops operation.
Note: Should the engine continue operating even
after the manual stop lever is operated, 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 the fuel injection pump to stop fuel injection, thus
shutting down the engine operation.
The "RUN-ON" type solenoid sets the start switch to
the "OFF" position by de-energizing the stop sole-
noid and pushing the rod out by internal spring
power which makes the rack of the fuel injection
pump move to the non-injection direction.
