TROUBLES AND ACTIONS

ACTIONS WHEN RUNNING OUT OF FUEL

When starting the engine again after running out of fuel, fill with fuel, and bleed the air from the fuel system
before starting the engine.
Always check the fuel level to prevent running out of fuel.
If the engine has stopped due to run out of fuel, all air must be sufficiently bled from the fuel circuit.
PROCEDURES FOR BLEEDING AIR FROM FUEL CIRCUIT
1.
Turn the starting switch key to OFF position (A) and stop
the engine.
2.
Loosen the knob of feed pump (1), pull it out, then pump it
in and out until the movement becomes heavy.
REMARK
It is not necessary to remove the plugs at the fuel prefilter
head and at the fuel main filter head.
3.
Push in and tighten the knob of feed pump (1).
4.
Turn the starting switch key to START position and start
the engine.
Do not operate the starting motor continuously for more
than 20 seconds. If the engine does not start, wait for at
least 2 minutes before trying again. Perform this operation a maximum of 4 times.
