9. Clean the foam element in warm, soapy water or in a
nonflammable solvent.
Note: Do not use gasoline to clean the foam element
because it could create a risk of fire or explosion.
10. Rinse and dry the foam element thoroughly.
11. Dip the foam element in clean engine oil, then squeeze
out the excess oil.
Note: Excess oil in the foam element restricts the air
flow through the element and may reach the paper
filter and clog it.
12. Wipe dirt from the base and the cover with a moist rag.
Note: Be careful to prevent dirt and debris from
entering the air duct leading to the carburetor.
13. Install the air cleaner elements and ensure that they are
properly positioned.

Avoid contacting the hot engine oil when you
drain it.
2. Stop the engine and wait for all moving parts to stop.
3. Disconnect the wire from the spark plug.
4. Place a suitable drain pan under the dipstick/oil drain.
5. Clean around the dipstick.
6. Remove the dipstick by rotating the cap
counterclockwise and pulling it out.

drain the oil from the dipstick fill tube into the drain
pan.
