Fuel system, bleeding

The fuel system must be bled if the fuel tank has been
run dry and after a long-term stoppage.
1 Remove the protective cap from the bleed nipple
(1).
Connect a transparent hose to the bleed nipple.
Feed the hose to a container to avoid spillage.
2 Open the bleeding nipple and pump fuel with the
hand pump (2) until the fuel is free from bubbles.
3 Close and tighten the bleed nipple.
4 Start the engine.
If the engine runs unevenly there might be air left in
the fuel system. To empty the system of remaining
air, open the bleed nipple while the engine is
running.
WARNING!
Hot fuel can cause burns.
WARNING!
Working with or approaching a running engine is a
safety risk. Watch out for rotating components and hot
surfaces.
5 Close the bleed nipple. Remove the hose and fit the
protective cap to the bleed nipple.
