Maintenance. Fuel system
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. Attach a transparent hose to the air vent valve (1).
Lead the hose to a suitable receptacle to avoid
spillage.
2. Open the air vent valve and pump fuel using the
hand pump (2) until the fuel running out is free
from air bubbles. Close and tighten the air vent
valve.
3. Pump another 10 strokes with the hand pump. The
resistance in the hand pump may seem quite high
and is normal and necessary for bleeding the sys-
tem.
4. Remove the hose and refit the protective cap on
the air vent valve.
WARNING!
Working on or approaching a run-
ning engine is a safety hazard. Beware of rotating
parts and hot surfaces.
