BLEEDING THE FUEL CIRCUIT
WARNING
q
The engine may start during the bleeding operations; make sure that there is no one near the machine.
1. After filling the fuel tank, ensure that the filter valve (1) is in
the open position (B).
2. Turn the ignition key to position ON and wait approximately
10-15 seconds, in such a way as to allow the fuel system to
be automatically bled.
3. Turn the ignition key to position START and start the engine.
IMPORTANT
q
If the engine starts regularly and then stops or functions ir-
regularly, check if there is air in the circuit; in this case,
check the tightness of the fuel filter and of the fuel pump
prefilter.
q
When all the fuel in the tank has run out, bleed the circuit
by proceeding as described above and repeat the opera-
tion at least twice.
