7. Maintenance procedures

7.1. Cleaning the air filter (diagram C)
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 (1) attaching the air filter cover (2), then remove the latter.
Remove the wing nut attaching the filter.
Remove the assembly consisting of foam (3) and paper (4) elements, and separate them. Check carefully that the two elements
are not torn or pierced. Replace them if they are damaged.
Foam element (3):
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 (4):
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 (diagrams A, D and E)
Move the noise reducing deflector (23) forwards.
Close the fuel tap (no. 14, Fig. A).
Unscrew the plug (no. 1, Fig. D) to drain fuel.
Refit and tighten the plug (no.1, Fig. D).
Remove the sediment 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 with a high flash point. Dry it fully.
Refit the seal and the bowl.
Tighten the bowl.
Open the fuel tap (no.14, Fig. A) and check that there are no leaks.
Move the noise reducing deflector (23) back to its initial position.
7.3. Renewing the motor oil (diagram B)
Change the oil when the engine is still warm, to ensure that drainage is rapid and complete.
Remove the filling plug-gauge (1) and the drain plug (3) and drain the oil into a suitable container.
On completion, screw up again and tighten the drain plug (3).
Fill the engine oil sump with the recommended oil, then check the level.
Put in place and tighten the filling plug-gauge (1).
Check that there is no oil leak after filling.
Wipe off any trace of oil with a clean cloth.
7.4. Cleaning the spark arrester (diagram F)
Loosen the two nuts (1) by 12 mm and remove the cylinder silencer (2).
Loosen by 5 mm the five bolts (3) and (4) holding the silencer guard (5) and then remove silencer guard.
Withdraw by 4 mm the bolt (6) attaching the spark arrester (7) and remove the spark arrester.
Using a wire brush, remove the carbon deposits from the spark arrester screen.
Note: The spark arrester must have no holes or cracks. Replace if necessary.
Refit the spark arrester (7), the guard (5) and the silencer (2) in the reverse order to removal.
