2.1 Procedures and Checks
Note: It is recommended that you operate the engine on diesel oil as an
alternative to heavy fuel oil for some time before engine shutdown (see
Change−over from Diesel Oil to Heavy Fuel Oil and Back 0270−1).
Note: The numbers (e.g. 30-8605_E0_7) refer to items shown in the control
diagram 4003−2.
1) Close the stop valves on the starting air bottles.
2) Turn the handwheel 2.10 on the shut-off valve for starting air 2.03 to the position
CLOSED.
3) Open the vent valves 2.21 and 2.27.
4) Make sure that the pressure gauges show zero pressure.
WARNING
Injury Hazard: Before you operate the turning gear, make sure
that no personnel are near the flywheel.
5) Engage the turning gear.
Note: The water and oil pumps must operate for a minimum of 20 minutes after
the engine has stopped. This is to make sure that when the engine
temperature has decreased, the temperature of engine parts become as
stable as possible.
6) Open the indicator valves on the cylinder covers.
Post-lubrication starts automatically during the slow-down of the engine.
7) When the engine has stopped, cut out the fuel pumps, see 5556−2 paragraph 1
