Inspection after stopping
Inspect the engine for leaks of fuel, oil or coolant. If any leak is found, repair the leak or contact a dealer of Mitsubi-
shi Heavy Industries, Ltd.
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, idle the engine in low for 5 or 6 minutes
to perform cooling operation, 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.
When stopping the engine by pulling the manual
stop lever, continue pulling the lever until the engine
stops completely. If not, the engine may start again.
