7. Maintenance procedures

7.1. Cleaning the air filter

Never use petrol or flammable solvents for cleaning the air filter element (risk of fire or explosion).
Important
Remove wing nut and cover from the air filter (diag. D - no. 1 & 2).
Remove the filter elements (diag. D – no. 4 & 5) and clean them:
Paper element (diag. D - no. 4):
1) Gently tap the element several times on a hard surface to remove any excess dirt.
OR: Pass compressed air through the filter, from the inside out.
Never try to remove dirt using a brush.
2) Replace the paper element if it is too dirty.
Foam element (diag. D - no. 5):
3) Wash the element in a solution of household cleaner and warm water and rinse thoroughly.
OR: wash with non-flammable solvent or solvent with a high flash point. Allow the element to dry completely.
4) Soak the element in clean engine oil and remove the excess oil.
Note: If there is too much oil remaining in the foam, the engine will emit smoke when it is first started.
Check carefully that the two elements are not torn or pierced. Replace them if they are damaged.
Carry out refitting following the reverse procedure for removal.
