A dirty air filter restricts air flow to the carburetor, reducing engine 
performance. If you operate the mower in very dusty areas, clean the 
air filter more often than specified in the MAINTENANCE SCHEDULE 
(page 24).

Operating the engine without an air filter, or with a damaged filter, will 
allow dirt to enter the engine, causing rapid engine wear. This type of 
damage is not covered by the Distributor’s Limited Warranty (page 57).

1. Press down on the cover tabs, then remove the cover.

2. Remove the filter and inspect it; if damaged, replace the filter.

3. Clean the filter by tapping the filter several times on a hard surface 

to remove dirt, or blowing compressed air [not exceeding 30 psi 
(207 kPa)] through the filter from the inside. Never try to brush off 
dirt; brushing will force dirt into the fibers.

4. Wipe dirt from the inside of the air cleaner housing and cover, 

using a moist rag. Be careful to prevent dirt from entering the air 
duct that leads to the carburetor.

5. Reinstall the filter and cover.
