IMPORTANT: Used motor oil may cause skin cancer
if repeatedly left in contact with the skin for prolonged
periods. Although this is unlikely unless you handle used
oil on a daily basis, it is still advisable to thoroughly wash
your hands with soap and water as soon as possible
after handling used oil.

NOTE: Please dispose of used motor oil in a manner that
is compatible with the environment. We suggest you take
it in a sealed container to your local service station for
reclamation. Do not throw it in the trash or pour it on the
ground.

Remove the wing bolt and the air cleaner cover.
Remove the elements and separate them. See Figure

Carefully check both elements for holes or tears
and replace if damaged.
2.
Foam element: Wash the element in a solution of
household detergent and warm water, then rinse
thoroughly, or wash in nonflammable or high flash
point solvent. Allow the element to dry thoroughly.
Soak the element in clean engine oil and squeeze out
the excess oil. The engine will smoke during initial
start-up if too much oil is left in the foam.
Paper element: Tap the element lightly several times
on a hard surface to remove excess dirt, or blow
compressed air through the filter from the inside out.
Never try to brush the dirt off; brushing will force
dirt into the fibers. Replace the paper element if it is
excessively dirty.
