7. Maintenance procedures

7.1. Cleaning the air filter

Never use petrol or solvents with a low flash point for cleaning the air filter element as this could result in a fire or
explosion.
Danger
Remove the wing nut (no. 1, fig. C) attaching the air filter cover (no. 2, fig. C), then remove the latter.
Remove the wing nut attaching the filter.
Remove the assembly consisting of foam (no. 3, fig. C) and paper (no. 4, fig. C) elements, and separate them. Check carefully that
the two elements are not torn or pierced. Replace them if they are damaged.
Foam element (no. 3, fig. C):
A)
Wash the element in a solution of household cleaning product and warm water, then rinse thoroughly, or wash it in non-
flammable solvent or solvent with a high flash point. Leave the element to dry fully.
B) Soak the element in clean engine oil and remove the excess oil. The engine will smoke when it is started for the first time if too
much oil remains in the foam.
Paper element (no. 4, fig. C):
Tap the element lightly several times on a hard surface to remove excess dirt, or send compressed air through the filter, from the
inside outward. Never try to remove dirt using a brush. Replace the element if it is too dirty.
Carry out refitting following the reverse procedure to that used for removal.
7.2. Cleaning the sediment bowl
Switch off the fuel tap (no. 14, fig. A).
Unscrew the plug (no. 1, Fig. D) to drain the fuel.
Fit the plug (no.1, Fig. D) back on.
Remove the bowl (no. 1, Fig. E) and the seal (no. 2, Fig. E).
Wash the bowl (no. 1, Fig. E) with non-flammable solvent or solvent having a high flash point. Leave to dry fully.
Refit the seal and the bowl.
Open the fuel tap (no.14, Fig. A) and check that there are no leaks.
