Engine Maintenance
Servici ng the A ir Cleaner
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, d irty conditions.

new elements carefully; do not use if the
rubber seal or foam sleeve is damaged.
4. Clean all air cleaner components of any
accumulated dirt or foreign material.
Prevent any dirt from entering the
