Environment
Since the engine may be running during filter re-
newal, fuel may spill. Use a suitable container.
Used fuel must be disposed of as specified in na-
tional and international law.
While running, the rotary control should point
90° towards the filter used.
1. Turn the rotary control 90° to the right so that
it points towards filter B. The fuel then flows
through the filter.
2. Connect a transparent plastic hose to the
bleed nipple located above filter A. Place the
other end in a container with a capacity of at
least 3 litres (1 US gallon).
3. Open the bleed nipple on side A; the remain-
ing pressure is released.
4. Clean the exterior of the filter with a cloth.
5. Unscrew the filter.
6. Apply oil to the gasket on the new filter.
7. Screw the filter into place by hand until it
makes contact.
8. Turn screw a further half turn by hand.
9. Turn the rotary control 90° to the left so that
the rotary control points straight up. Both fil-
ters now run simultaneously.
10. When fuel without air bubbles comes out,
close the bleed nipple. Because the engine is
running, a lot of fuel will come through the
hose.
11. Turn the rotary control 90° to the left so that
the pin points towards filter A. Filter B can
then be renewed following the procedure de-
scribed for filter A.
