Checking and topping up oil level
The oil level should be within the marked area on the dip-
stick (1) and should be checked every day before the first
time the engine is started.
Topping up is done on the top of the engine. Top up oil
slowly. Wait a few minutes before checking the oil level
again to give the oil time to run down to the oil pan. Then
check the level again. Use only the recommended grades
of oil: See the chapter "Technical Data".
IMPORTANT! Do not fill the oil above the MAX level.
NOTE! Between MAX and MIN there are apporx. 1,5 liter
(0,4 US gals) for D4 and 3,5 liter ( 0,9 US gals) for D6.
Engine oil. Change
Always observe the recommended oil change interval.
1. Start the engine (this makes it easier to suck the oil
up from the sump). Let the engine run till operation
temperature is reached (temperature gauge indicate a
value between 75– 95°C (167-203°F)). Then stop the
engine. Wait ten minutes before draining the oil.
WARNING! Hot oil and hot surfaces can cause
burns.
2. Connect the oil bilge pump to the drain pipe. Pump up
the oil.
3. Change the oil filter and bypass filter at each oil
change (please refer to chapter "Changing oil filter and
bypass filter").
4. Fill up with oil to the correct level through the filling
hole on the top of the engine (please refer to the
"Technical Data" chapter for oil volume).
IMPORTANT! Only use a recommended grade of
oil (please refer to previous page).
5. Start the engine. Check that the low oil pressure warn-
ing lamp goes out and that no leakage occurs by the
filters.
Let the engine run till operation temperature is reached
(temperature gauge indicate a value between 75– 95°C
(167-203°F)).
IMPORTANT! The oil level check must be done
on a warm engine. If the oil is cold it will take very
long time for the oil to flow back into the oil sump.
WARNING! Working with, or going close to a run-
ning engine is a safety risk.Watch out for rotating
components and hot surfaces.
6. Stop the engine. Wait ten minutes before checking the
oil level. Top up if necessary.
NOTE! Hand the old oil in to a re-cycling station.
