This engine is equipped with a replaceable, high
density paper air cleaner element. Check the air
cleaner daily or before starting the engine. Check for
a buildup of dirt and debris around the air cleaner
system. Keep this area clean. Also, check for loose or
damaged components. Replace all bent or damaged
air cleaner components.
Note: Operating the engine with loose or damaged
air cleaner components could allow unfiltered air into
the engine, causing premature wear and failure.
Note: Service the air cleaner more often under
extremely dusty, dirty conditions.

blade control switch, move the motion control
levers to the brake position, stop the engine,
remove the key, and wait until all moving parts
