HOW TO CLEAN THE AIR FILTER

The engine uses a foam air filter that can be
cleaned and reused. Clean and oil the air
filter every 25 hours. Clean more often in
dusty conditions. Remove and clean the air
filter as follows:
CAUTION: Never run the engine without
the air filter installed. An air filter clogged
with dust can result in loss of engine
power and can cause excessive wear or
damage to the engine. If the air filter is
clogged, clean or replace immediately.
1. Disconnect the spark plug wire from the
spark plug.
2. Remove the screws from the air filter
cover (see Figure 12). Remove the air
filter cover and the air filter.
3. Wipe the cover and the inside of the air
filter housing with a clean cloth.
4. Clean the air filter in a solution of water
and household detergent. Rinse tho-
roughtly in clean water.
5. Wrap the air filter in a dry clean cloth.
Squeeze out (do not twist) all solution
