AIR FILTER MAINTENANCE
_L_ WARNING: To avoid serious personal injury, always turn
your unit off and allow it to cool before you clean or service it.
The condition of the air filter is important to the operation of the unit. A dirty air
filter will restrict air flow and change the air/fuel mixture. This is often mistaken
for an out of adjustment carburetor. Check the condition of the air filter before
adjusting the idle speed screw. Referto Air Filter Maintenance.

(Fig. 13). Use a flat blade or T-20 Torx bit screwdriver.

Failure to maintain your air filter properly can result in poor
performance or can cause permanent damage to your engine.
1. Remove air filter/muffler cover. Refer to Removing the Air
Filter/Muffler Cover above.
2. Turn cover over and look inside to locate the air filter. Remove the
air filter from inside the air
filter/muffler cover (Fig. 14).
3. Wash the filter in detergent
and water (Fig. 15). Rinse
the filter thoroughly.
Squeeze out excess water.
Allow it to dry completely.

30 oil to lightly coat the
filter (Fig. 16).
