Protective fuel mixture
So as to protect your engine well during the standstill
of the winter season, it is recommended to have the
engine running for some 10 minutes with a protective
mixture of 10% lubrication oil and 90% of clean diesel
fuel.
With this mixture: idling revolutions
only, no revving up allowed!

Lubrication oil system
Replace the oil filter and change the engine lubrication
oil with a good quality of oil, with protective proper-
ties. See page 26.
Raw water cooling system
Close the raw water seacock and clean the raw water
strainer. Drain so much cooling liquid from the inner
cooling circuit, so as to enable you to add 1 liter of
(extra) anti-freeze into the cooling circuit. Have the
motor idling for a few seconds, so that the additional
anti-freeze can be spread throughout the system.
Anti-freeze liquid is very poisonous !
Make sure anti-freeze is not getting
mixed up with raw water
When closing the cover of the raw water strainer,
make sure that it tightens well. If false air is coming
into the system through a cover that is not closed
tightly, there is a severe risk of overheating of the
engine.
