Section 12.4 Stopping

Section 12.4
Stopping

The following should be performed for NORMAL stopping:‪

  1. Release the load and decrease the "engine speed" in the NEUTRAL position.

    NOTICE:

    Stopping a turbocharged engine immediately after high speed operation may cause damage to the turbocharger, as it will continue to turn without an oil supply to the bearings.‪

  2. Allow the engine to run at idle with no-load for four or five minutes. This allows the turbocharger to cool and slow down. Then turn the key switch to the OFF position.

Section 12.4.1
Emergency Stopping

To stop the engine, turn the key to the OFF position.‪

NOTICE:

Never use the emergency shutdown system, except in an emergency. Use of the emergency shutdown can cause turbocharger damage.‪

NOTICE:

If the emergency air shutdown is used to stop the engine in an emergency situation, always have the shutdown checked for damage and for proper operation before the vessel is returned to service. This is especially important if shutdown is made at high engine rpm. To ensure positive valve closure should another emergency shutdown be required, the shutdown must be checked and required repairs or adjustments made at this time. Failure to observe this precaution may permit engine run-on when the emergency shutdown is activated.‪

The emergency shutdown should be used only when the engine does not respond to the normal stop engine procedure.‪

To shut down the engine, simply activate the emergency shutdown control. This is an electrical switch which is normally identified as such on the control panel.‪

The air shutdown must be reset by hand. If an "emergency stop" knob connected to a bowden wire is also installed on the shutdown, this should be pushed in before the engine is ready to start again.‪
