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
Undo the four 10 mm bolts holding the closure panel in place starter end, and remove the panel (diag. B).
Unfasten both retaining clips (no. 1, diag. F) from air filter cover (no. 2, diag. F) and remove the cover.

Soak the element in clean motor oil and remove the excess oil. If too much oil remains in the foam, the motor will smoke when it
is first started.
Refit the filter cover and ensure that it is clipped securely in place.
