Stop; Emergency Stop; Inspection After Stopping - Mitsubishi S6B3 Operation & Maintenance Manual

Stop

Stopping the engine abruptly while engine parts are hot due to high-speed operation can be a cause for heat up of
the engine parts and shorten the engine life. Before stopping the engine, run the engine with the idle speed at low
Rpms for 5 or 6 minutes to cool the engine, and check the engine for abnormalities.
Never accelerate the engine immediately before shutting it down.
Do not restart the engine immediately after abnormal shut down. When the engine stops with alarms, be sure to
locate the cause of the problem and correct the problem before restarting the engine. After restarting the opera-
tion, check the engine for abnormalities again. If the engine has an abnormality, repair it immediately.
Engine stopping method varies depending on the specifications.
To stop the engine, follow the instructions of the equipment.

Emergency Stop

stop lever, continue pulling the lever until the engine
stops completely. If not, the engine may start again.
To perform the emergency stop, pull the manual stop
lever to the arrow direction. Continue pulling the lever
until the engine stops completely.
Note: When the engine does not stop even if the man-
ual stop lever is pulled, stop fuel supply.
