Engine Maintenance

Servicing the Air Cleaner
Service Interval: Every 25 hours/Monthly
(whichever comes first)
(May need more often
under extremely dusty or

(whichever comes
first)—Replace the paper
element. (More often

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.

Servicing Paper Element
Service Interval: Every 25 hours/Monthly
1. Remove the air cleaner cover (Figure 18).
2. Remove the air cleaner element with the integral
rubber seal.
3. Remove the foam sleeve from the element.
4. Gently tap the pleated side of the paper element
to dislodge dirt. Do Not wash the paper element
or use pressurized air, as this will damage the
element. Replace a dirty, bent, or damaged
element. Handle new elements carefully; Do Not
use if the rubber seal or foam sleeve is damaged.
5. Wash the foam sleeve in warm water and allow to
dry. Reinstall over the paper element.
6. Clean all air cleaner components of any
accumulated dirt or foreign material. Prevent any
dirt from entering the carburetor.

side "out" and seat the rubber seal onto the edges
of the air cleaner base.

the knobs.

Servicing the Engine Oil

Checking the Oil Level
Service Interval: Before each use or daily
1. Park the machine on a level surface, disengage
the blade control switch, stop the engine, engage
parking brake, and remove the key.
2. Make sure the engine is stopped, level, and is cool
so the oil has had time to drain into the sump.
3. To keep dirt, grass clippings, etc., out of
the engine, clean the area around the oil fill
cap/dipstick before removing it.
4. Pull and remove the oil fill cap/dipstick; wipe oil
off. Reinsert the dipstick and push firmly into
place (Figure 19).
