7. Maintenance procedures

7.1. Cleaning the air filter (diagram F)
Never use petrol or flammable solvents for cleaning the air filter element as this could result in a fire or
explosion.
Danger
Remove the air filter cover (No. 1) by unclipping both clips (No. 2) then remove the foam element (No. 3).
Clean the foam element (No. 3) with household detergent diluted in warm water then rinse it through or wash it in non-flammable
solvent or solvent with a high flashpoint. Leave to dry fully.
Soak the element in clean motor oil and wring it out to remove excess oil. The motor will smoke when it is started for the first
time if too much oil remains in the foam.
Reinsert the air filter element and refit the cover in the opposite order to removal.
