Changing fuel filters

Only use filters with a filtration level equivalent to the ones you are

replacing (see section FREQUENCY).

If you intend to proceed with the engine stopped

Only proceed with the engine at a low temperature, so as to avoid the

risk of burning.

 Remove the filters (2/3) by unscrewing them.

 Damp the new filter seal with gasoline or engine oil.

 Hand screw the new filters into place until the seal gasket touches

the support, then lock by a further 3/4 of a turn.

 Bleed any residual air as described below.

If you intend to proceed with the engine turning

The support with switching lever means that, if necessary, the filters

can be replaced even with the engine turning.

The instructions given above for replacement are dependent on the

lever being turned as described below:

 Switch the lever (1) to position A and replace filter (2).

 Switch the lever (1) to position B and replace filter (3).

 Return the lever (1) to the central position so that you do not re-

strict the flow of fuel feeding the engine.

 Bleed any residual air as described below.

CAUTION!

Proceed with extreme caution, given the high temperature

of the fluid and the presence of moving parts. Always wear

suitable personal protection equipment.

WARNING

Do not fill the new filters until they have been fitted on the support,

to avoid the risk of any harmful impurities entering the injection sys-

tem and circuit.
