Service Precleaner and Air Cleaner Element

This engine is equipped with a replaceable, high

density paper air cleaner element. Some engines are

also equipped with an oiled, foam precleaner, located

in the outer air cleaner cover. See Figure 9.

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.

3. 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 with a genuine Kohler element. Handle

new elements carefully; do not use if the rubber

seal is damaged.

4. Clean all air cleaner components of any

accumulated dirt or foreign material. Prevent

any dirt from entering the throat of carburetor.

5. Install the air cleaner element with the pleated

side "out" and seat the rubber seal onto the edges

of the air cleaner base. See Figure 11.

6. Reinstall the precleaner (if so equipped), into the

upper section of the air cleaner cover. Make sure

the hole in precleaner is aligned with the upper

mounting knob. See Figure 9.
