Fuel filter change
Only use filters with the following specifications (see the section
FREQUENCIES):
- degree of filtering < 12 μm
- filtering efficiency 99.5% (ß > 200).
Only proceed when the engine is not turning and is at low
temperature so as not to run the risk of burns.
Place a container for collecting the diesel under the filter support
(1).
Remove the filter (2) by unscrewing it from its relative support.
Replace the filter element and the O-ring seal contained inside the
filter (2).
Carefully clean the surfaces of the support (1) in contact with the
O-ring seal.
Moisten the O-ring seal of the new filter with oil.
Screw the new filter (2) onto the support (1)
Residual air bleeding procedure:
Loosen the fuel outlet coupling (1) located on the top of the filter.
Make sure that the discharge of diesel does not soil the ancillary
belt and does not leak into the surroundings.
Operate the lever (3) of the fuel suction pump (2) until the diesel
coming out is free from any residual air.
Correctly tighten the previously loosened coupling.
Start the engine and let it run idle for a few minutes to remove any
residual air.
