Since the engine may be running during filter re-
newal, fuel spillages may occur. Use a suitable
container. Used fuel must be disposed of as spec-
ified in national and international law.
During operation, the rotary control should point
90° towards the filter being 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 fuel filter into place by hand until
it makes contact. Turn screw a further half
turn by hand.
8. Turn the rotary control 90° to the left so that
the rotary control points straight up. Both fil-
ters now run simultaneously.
9. 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.
10. Turn the rotary control 90° to the left so that
the rotary control points towards filter A. Fil-
ter B can now be renewed in the same way as
filter A.
