Stopping; Inspection After Stopping - Mitsubishi S4S-DT Operation & Maintenance Manual

Chapter 3 OPERATION

Stopping

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 gear immediately
until the engine temperature becomes normal except in an emergency. Then, perform cooling operation for 5 or 6
minutes before stopping the engine and inspect the whole engine.
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, inspect the whole engine for any abnormalities again. If the engine has an abnormality, repair it immediately.
Engine stopping method may differ depending on the specifications.
Follow the instructions according to the specifications of the equipment.

Inspection after stopping

Inspect the engine for fuel, oil or coolant leakage. If any leakage is found, repair the leakage or contact a dealer of
Mitsubishi Heavy Industries, Ltd.
