5. Clean the air filter elements if they are to be reused.
Paper air filter element: Tap the filter element several times on a
hard surface to remove dirt, or blow compressed air [not
exceeding 207 kPa (2.1 kgf/cm , 30 psi)] through the filter
element from the inside. Never try to brush off dirt; brushing will
force dirt into the fibers.
Foam air filter element: Clean in warm soapy water, rinse, and
allow to dry thoroughly. Or clean in nonflammable solvent and
allow to dry. Dip the filter element in clean engine oil, then
squeeze out all excess oil. The engine will smoke when started if
too much oil is left in the foam.
6. CYCLONE TYPE ONLY: Remove the three pan-head screws from
the precleaner cap, then remove the cyclone housing and air
guide. Wash the parts with water, dry them thoroughly, and
reassemble them.
Be sure to install the air guide as shown in the illustration.
Install the cyclone housing so the air intake tab fits into the
groove in the precleaner cap.
7. Wipe dirt from the inside of the air cleaner base and cover, using
a moist rag. Be careful to prevent dirt from entering the air duct
that leads to the carburetor.
8. Place the foam air filter element over the paper element, and
reinstall the assembled air filter. Be sure the gasket is in place
beneath the air filter. Tighten the air filter wing nut securely.
9. Install the air cleaner cover, and tighten the cover wing nut
securely.
