AIR FILTER MAINTENANCE
NOTE: Clean and re-oil the air filter after every 10 hours
of operation. Your unit's air filter is one of the
most important areas to maintain. If it is not
maintained, you will VOID the warranty. Before
cleaning, make sure the unit is turned off.
1. Wipe down the air filter cover and surrounding area.
This will help prevent any debris entering the
carburetor when the cover is removed.
2. Remove the screws on each side of the
carburetor/air filter cover assembly. Remove
the carburetor/air filter cover (Fig. 16).
3. Remove the air filter (Fig. 17).
4. Wash the filter in detergent and water (Fig. 18). Rinse
the filter thoroughly and allow it to dry.
5. Apply enough clean SAE 30 oil to lightly coat the
filter (Fig. 19).
