Renewing the oil filter
Clean the centrifugal oil cleaner at the same time
as you change the oil filter. Otherwise, the oil fil-
ter will become blocked and the resistance in the
filter will increase. If this happens, an overflow
valve in the filter retainer opens and lets the oil
pass without being filtered.
1. Remove the old filter.
2. Oil the rubber gasket on the new filter.
3. Tighten the filter by hand. Never use tools
because the filter could sustain damage, ob-
structing circulation.
4. Start the engine and check for leaks.
Renewing the commutative
oil filter
While driving, the rotary control (1) should point
upwards to minimise pressure losses in the filter
unit; see right-hand illustration.
1. Turn the rotary control 90° to the right so that
it points towards filter B. The oil then flows
through the filter.
2. Clean filter A with a cleaning cloth.
3. Unscrew filter A.
4. Apply oil to the gasket on the new filter.
5. Fill the filter with engine oil.
6. Screw filter A into place by hand until it
makes contact.
7. Turn screw a further half turn by hand.
8. Turn the rotary control 90° to the left so that
the rotary control points towards filter A.
Then renew filter B in the same way as filter
A.
