ENGINE AIR FILTER CHECK/CLEANING

CAUTION!
Running the engine without air filters, or with
damaged filters, can cause a faster engine
wearing.
1. Drive the machine on a level ground and engage the
parking brake.
2. Turn the ignition key (61) to "0".
3. Open the engine compartment hood (18) with the handle
(41) and fasten it with the support rod (53).
4. Lift and disassemble the right side bulkhead (45).
5. Remove the wing nut (A, Fig. 21) and remove the cover
(B).
6. Remove the wing nut (C) and disassemble the filter
element.
7. Separate the foam filter (D) from the paper filter (E).
8. Check both filters and replace them if necessary. Replace
the paper filter (E) when required (see the scheduled
maintenance table).
9. To use again the filters, clean them as shown below:
• Paper filter (E): Hit the filter several times against a
hard surface to remove the dust, or blow compressed
air (no more than 207 kPa (2.1 kgf/cm)) from inside the
filter. Do not use a brush, otherwise the fibre will be
damaged.
• Foam filter (D): Clean with warm water and soap, rinse
and let it dry completely, or clean with a non-flammable
solvent and let it dry. Soak the filter in clean engine oil,
then squeeze it to remove the surplus oil.
10. Clean with a wet cloth the base (F) and the cover (B) of the
air filter. Pay attention to avoid that dirt enters the air duct
(G) to the carburettor.
11. Assemble the foam filter (D) on the paper filter (E), then
assemble the filter element. Ensure that the gasket (H) is
properly placed under the filter element. Screw down the
filter element wing nut (C).
12. Install the cover (B) and screw down the wing nut (A).
