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
air cleaner 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 nuts, 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 elements
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 seals on the air
cleaner studs. If they are worn, damaged, or their
condition is questionable in any way, replace them
with the new seals packaged with the new
element.
7. Reinstall the paper element, precleaner, element
cover, element cover nut, and air cleaner cover.
Secure cover with the cover retaining knob.
8. When element replacement is necessary, order
genuine Kohler parts.
