Service Precleaner
If so equipped, wash and reoil the precleaner every 25
hours of operation (more often under extremely dusty
or dirty conditions).
1. Loosen the cover retaining knob and remove the
cover.
2. Remove the precleaner from the paper element.
3. Wash the precleaner in warm water with
detergent. Rinse the precleaner thoroughly until
all traces of detergent are eliminated. Squeeze out
excess water (do not wring). Allow the precleaner
to air dry.
4. Saturate the precleaner with new engine oil.
Squeeze out all excess oil.
5. Reinstall the precleaner over the paper element.
6. Reinstall the air cleaner cover. Secure cover with
the cover retaining knob.
7. When precleaner replacement is necessary order
genuine Kohler Parts.
Service Paper Element
Every 100 hours of operation (more often under
extremely dusty or dirty conditions), replace the
paper element.
1. Loosen the cover retaining knob and remove the
cover.
2. Clean the area around the element to prevent
debris from getting in the engine when element is
removed.
3. Remove the element cover wing nut, element
cover, and paper element with precleaner.
Separate the precleaner from the element and
service as necessary.
4. 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 element
carefully; do not use if the sealing surfaces are
bent or damaged.
5. When servicing the air cleaner, check the air
cleaner base. Make sure it is secured and not bent
or damaged. Also, check the element cover for
damage or improper fit. Replace all damaged air
cleaner components.
6. Check the condition of the rubber seal on the air
cleaner stud. If it is worn, damaged, or its
condition is questionable in any way, replace it.
