MAINTENANCE
47.3 Oil and oil filter change
1. Change the oil and the oil filter after the initial 50
service hours of a new or reconditioned engine
and, thereafter, every 250 service hours or once a
year (whatever comes first).
2. Warm up the engine. Remove the drain plug and
allow the oil to drain in a container.
3. Remove the used filter with a filter wrench. Make
sure that the formely used O-ring is removed from
the filter base and clean the base with a cloth.
4. Check the new oil filter and make sure that the O-
ring is fitted in the groove. Apply a thin coat of lube
oil to the O-ring of the new oil filter.
5. Install the new filter by hand untill the O-ring
touched the base. Tighten 3/4 to 1 turn more.
6. Install the drain plug and tighten it to the specified
torque.
7. Re-fill the engine to the "H" mark on the dipstick
with the new oil. Approximately an additional 0.5
liter (0.5 qt) of oil is required for the oil filter and oil
lines.
8. Start the engine, leave it idling for a few minutes
and check for leaks. Re-tighten the filter in case of
leakage.
9. Stop the engine. Check the oil level and add oil if
necessary.

Discard the filter.
3. Remove all of the old filter gasket from the filter
base and apply a thin coat of engine oil to the
gasket on the new filter. Install the filter by hand
until its gasket contacts the base. Tighten 3/4 turn
more.
