Top: Loosening the slotted nut Center: Remove carburetor box cover Bottom: Removed filter Clogged air filters reduce the power of the engine, increase the fuel consumption and make starting more difficult. The air filter must be cleaned daily - under extreme dust conditions more often! Before removing clean the air filter and its surrounding area from dust. Close choke shutter - put choke lever to "CHOKE" position - so that no dust can drop into the carburetor. To remove the carburetor box cover turn lock to the left. Thereafter loosen the two slotted nuts in the air filter. Now the air filter can be pulled from the studs. For the daly cleaning it is sufficient to clean both filter parts with a soft brush. However, once a week the complete air filter should be washed in clean gasoline and if possible cleaned with compressed air. The reassembly is done in reverse sequence. It is advisable to always carry a spare filter with you and to clean the clogged one at home. 25
