Fuel system, bleeding
1. Clean around the air bleeding nipples on the cylin-
der head and the fuel filter bracket.
2. Bleed the fuel system at the fuel filter. Connect a
transparent plastic hose between the bleed nipple
(1) and a collection vessel.
3. Open the bleed nipple on the fuel filter bracket.
4. Pump with the hand pump until air-free fuel flows
out. Close the bleed nipple while the fuel is flowing
out.
5. Remove the hose and replace the protective cap
on the bleed nipples.
NOTE! When changing the fuel filter no additional
bleeding is required.
6. Move the hose to the cylinder head’s bleed nipple
(2) and bleed in the same manner as with the fuel
filter bracket.
7. Run the engine at a higher idle speed for
approximately 10 minutes to remove any
remaining air from the system.
