Maintenance
Fuel system. Venting
The fuel system must be vented after a filter change,
if the fuel tank has been run dry, after a long-term
stoppage etc.
Use the hand pump, if fitted, to vent the fuel system.
In other cases, vent the system by operating the
starter motor.
Fuel filter. Change
Cleanliness! No dirt must be allowed to get into the
fuel system.
WARNING! Fuel filters must be changed when
the engine is cold, to avoid the risk of fire due to
spilled fuel on hot surfaces.
Remove the filters. Wipe a film of oil on the gaskets
of the new filters. Screw the filters on by hand until
the gaskets just touch the mating surface. Then tight-
en a further half turn, no more. Vent the fuel system.
Hand old filters in to an authorized waste process-
ing facility for destruction.
Start the engine and make sure that no leakage oc-
curs.
