MAINTENANCE

If the engine seems weak or runs unevenly, the air 

filter may be clogged. If the machine is run with a 

dirty air filter, the spark plug can become fouled. It 

is important to replace the air filter regularly (see 

"Maintenance Schedule" for proper service intervals).
Kohler Engine
The standard engine is not equipped with a prefilter. 

As an option, a prefilter can be installed on the inside 

of the air filter cover.

1. Loosen the two retaining knobs and remove 

the cover. If the engine has a prefilter, it is 

mounted on the inside of the cover.

2. Clean the area around the filter element to 

prevent debris from getting into the engine 

when the element is removed.

3. Remove the filter element. Replace a dirty, 

bent or damaged element with a new one. 

Handle the new element carefully and do 

not use if the sealing surfaces are bent or 

damaged. If the element can be reused, tap it 

against a solid surface to remove dust.

4. Check the air cleaner base. Make sure it is 

secured and not bent or damaged. Also check 

the air filter cover for damage or improper fit. 

Replace all damaged air cleaner components.

5. Install the filter element. Check that it fits 

properly and that no air leaks occur.

6. Install the cover and tighten knobs by hand.
