WARNING
q
Change the filtering element after work, when the engine has cooled down to 40÷45°C.
q
During these operations some fuel may be spilled; clean the dirty areas immediately, in order to prevent
any risk of slipping or fire.
q
Oils, filters, the coolant and the battery are considered special waste and must be collected and dis-
posed of according to the regulations in force.
FUEL FILTER
1. Open the engine hood.
(For details, see "3.2.6 ENGINE HOOD").
2. Place a container under the filter to collect any spilt fuel.
3. Turn the valve (1) of the filter to the closed position (A).
4. Using a filter wrench, loosen the metal ring of the filter and
remove the casing (2).
5. Clean the head of the filter holder and the inside of the cas-
ing, install a new filter and fill the casing with fuel.
6. Lubricate the casing seal, install it on the filter holder and
tighten the metal ring until it touches the seal.
7. Give the metal ring a further 2/3 turn.
IMPORTANT
q
If the casing is tightened excessively, the seal may be dam-
aged and cause fuel leakages. Fuel leakages may also be
due to insufficient tightening. Therefore, it is advisable to
fix the casing by tightening the metal ring correctly.
