AIR FILTER

Your engine will not run properly and may be damaged by using a dirty air filter.

Replace the air filter every year, more often if you mow in very dusty, dirty conditions. Do not wash air filter.

,Clean engine often to keep trash from accumulating. A clogged engine runs hotter and shortens engine life.

•Keep finished surfaces and wheels free of all gasoline, oit,etc.
