9. Temperature
WARNING
Danger: If you think that parts of the running gear or bearings
have become too hot, it is possible that the engine must be shut
down. Before you open the crankcase doors, you must wait for a
minimum of 20 minutes. This will prevent an explosion.
WARNING
Injury Hazard. Be careful when you touch hot parts with your
hands. This can cause injury.
When commissioning an engine after an overhaul of its running gear, do a
temperature check to find unusually high temperatures in areas of the engine. Do this
temperature check after 10 minutes of engine operation.
Do the temperature check again after approximately one hour of engine operation.
After a short period of operation at full load, do the temperature check again.
10. Crankcase, Cylinder, Exhaust Pipes and Scavenge air
Receiver
Before you go into the spaces of the crankcase, cylinder, exhaust pipes and scavenge
air receiver, make sure that:
D The starting air to the engine is blocked and the ball valves 30-8605_E0_6 and
30-8605_E0_7 are open (see Control Diagram 4003−2).
D The turning gear is engaged (see the Maintenance Manual 0011−1 Precautionary
measures before you start maintenance tasks).
Note: Other ships in the water cause currents, which will make the propeller
and the engine turn. The engine and propeller cannot turn when the
turning gear is engaged.
11. Carbon Dioxide (CO
2)
Gas
WARNING
Injury Hazard. Where CO
2
is used to extinguish a fire in the
engine, there is a risk of suffocation. Make sure that all related
spaces have good airflow to remove all CO
2
gas before you go
into the engine.
12. Crankcase Doors − Close
Make sure that all crankcase doors are closed and locked before you operate the
engine. This is also applicable to short periods of engine operation e.g. running-in,
after the replacement of bearings etc.
