Air Cleaner Service
A dirty air filter will restrict 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 28).
NOTICE
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 66).
AIR CLEANER HOUSING
1. Press down on the cover tabs and remove the cover.
2. Remove the filter from the air cleaner housing.
3. Inspect the filter, and replace it if damaged.
4. Clean the filter by tapping the filter several times on a hard surface
to remove dirt, or blow 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.
5. 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.
6. Reinstall the filter and cover.
