4.7.11.e CHANGING THE FUEL FILTER
DANGER
•
Change the filtering element after work, when the engine has cooled down to 40-45°C.
•
When these operations are carried out, fuel may be spilled; clean the dirty areas immediately, in order to
prevent any risk of slipping or fire.
•
Oils, filters, coolants and batteries are considered special waste and must be collected and disposed of
according to the anti-pollution regulations in force.
The fuel filter and the fuel pump can be reached by opening the
engine hood (See “3.5.1 ENGINE HOOD”).
FUEL FILTER
1 - Clean the outer surfaces of the unit and with the special span-
ner provided unscrew the used filter (1) and throw it away.
2 - Clean the inside of the head (2).
3 - Lubricate the seal of the new filter and screw thoroughly.
4 - Give another half turn by hand.
5 - Bleed the fuel supply circuit.
BLEEDING THE CIRCUIT
After filling the tank, proceed as follows:
1 - Loosen the drain screw (3) of the filter holder head (2).
Use a 12 mm spanner.
2 - Unscrew the knob (4) of the fuel pump (5) completely.
3 - Act on the knob (4) until fuel without any trace of air flows out
of the filter head. Tighten the drain screw (3).
4 - Press the knob (4) and tighten it completely.
5 - Start the engine.
IMPORTANT
☞
•
If the fuel does not flow when the fuel pump lever is operat-
ed, give one turn to the driving shaft.
•
Do not let the starter run for more than 15 seconds. Wait at
least 15 seconds before repeating the starting procedure.
•
If the engine starts without problems and then stops or
works irregularly, check if there is air in the circuit; if so,
check the tightness of the fuel filter, the water separator
and the fuel pump.
•
After the fuel has run out, bleed the circuit by proceeding
as described above.
