BAir Bleeding the Fuel System
To avoid personal injury;
A DO NOT bleed a hot engine as this
could cause fuel to spill onto a hot
exhaust manifold creating a danger
of fire.
Air bleeding of the fuel system is required if;
A after the fuel filter and pipes have been detached and
refitted;
A after the fuel tank has become empty; or
A before the engine is to be used after long storage.
[PROCEDURE]
1. Fill the fuel tank with fuel.
2. Set the fuel lever to "OPEN" position.
3. Turn the key to "ON" for 30 to 40 seconds.
A With the key switch at "ON", the fuel electro-
mechanical pump can be activated automatically to
vent the air in the fuel pipes, hoses and filter.
A Always turn the key to "OFF" when air is vented and
the engine is not used, or it will cause the battery to
discharge.
