Maintenance: Fuel system
Fuel pre-filter. Replacing filter insert
WARNING!
Approaching a running engine is
dangerous. Watch out for rotating components
and hot surfaces.
1. Close fuel cock at the fuel tank. Position a contain-
er under the fuel filter.
2. Remove the cover by slackening off the screw (1).
3. Replace the insert (2) and reinstall the cover.
NOTE!
Deposit the old filter insert at a properly
designated disposal site.
4. Open fuel cock and vent fuel system, see "Bleed-
ing the fuel system" in this chapter.
5. Start the engine and check for leaks.
Bleeding the fuel system
The fuel system must be bled e.g. after changing fuel
filter, if the fuel tank has been run dry and after long
stops.
WARNING!
Never detach the pressure pipes.
1.
Position a container under the fuel filter.
2. Unscrew the venting screw on top of the filter
bracket (1).
3. Pump the fuel using the hand pump (2) on the filter
bracket until there are no more air bubbles visible
in the fuel. Continue pumping and at the same time
tighten the venting screw.
4. Pump another 10 strokes with the hand pump. The
resistance in the hand pump may seem quite high,
this is normal and necessary for bleeding the system.
5. Start the engine and check for leakages.
