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 properties.
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 coo-
ling 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.
