3.7.1 When machine runs out of fuel
WARNING
When starting the engine again, check carefully that the area
around the engine is safe before cranking the engine.
When starting the engine after running out of fuel, fill with fuel
and bleed the air from the fuel system before starting.
Always watch the fuel level and be careful not to run out of fuel.
If the engine has stopped because of lack of fuel, it is necessary
to use the priming pump to bleed the air completely from the fuel
circuit.
Procedure for bleeding air
WARNING
When opening air bleed plug (2) at the top of the fuel filter head
or the supply pump air bleeder, there is still remaining pressure,
so fuel may spurt out. Loosen carefully before opening.
1. Loosen plug (1) at the top of the fuel filter head, then remove
other plug (2).
NOTE
Do not loosen the plug of the fuel pre-filter head. This is at the
suction end, so if it is loosened, it will be impossible to bleed the
air.
2. Loosen butterfly nut (3) holding the lever of the priming
pump.
3. Operate the lever of the priming pump to prime with fuel.
Fuel will come out from plug (2) at the top of the fuel filter
head. Continue priming slowly until no more bubbles come
out with the fuel. Fit sealing tape to plug (2), then tighten it.
4. Continue priming a further 1 - 2 times. Check that fuel comes
out from plug (1), then tighten plug (1).
