Fuel system, bleeding
The fuel system must be bled after a filter change, if
the fuel tank has been run dry and after a long-term
stoppage.
IMPORTANT!
Never disconnect the pressure pipe.
1 Connect a transparent hose to the bleed nipple
(
1
). 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.
Close and tighten the bleed nipple.
3 Pump a further 10 times on the hand pump. Resist-
ance in the hand pump can feel heavy, but this is
completely normal and necessary to bleed the sys-
tem.
4 Remove the hose and fit the protective cap to the
bleed nipple.
