Servicing the Air Cleaner

Service Interval: Every 25 hours/Monthly (whichever comes first) (May need more often under extremely dusty or dirty conditions.)

Every 100 hours/Yearly (whichever comes first)—Replace the paper element. (More often under extremely dusty, dirty conditions.)

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 (whichever comes first) (May need more often under extremely dusty or dirty conditions.)

Every 100 hours/Yearly (whichever comes first)—Replace the air cleaner element.

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.

7.Install the air cleaner element with the pleated side “out” and seat the rubber seal onto the edges of the air cleaner base.

8.Reinstall the air cleaner cover and secure with 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).
