Changing the fuel filter
Avoid spillage and use a suitable container. Used fuel
must be disposed of as specied in national and inter-
national law.
NOTE
1. Unscrew the filter cover with a closed tool with hexagon
driver, e.g. socket, so as not to damage the filter cover.
2. Lift out the filter cover and filter element. The filter housing
will drain automatically. This applies only if the fuel tank is
lower than the engine. Otherwise the fuel shut-off cock
must be closed first.
3. Undo the removed filter element from the cover by
carefully bending it to one side.
4. Renew the O-ring in the cover. Lubricate the O-ring with Oring
grease.
5. Check that the filter housing is drained of fuel.
Contaminated fuel may enter the injectors if the drainage
does not work.
6. Press a new filter element into the snap fastener in the
cover.
