Cleaning
Air
Cleaner
Remove air cleaner cover. Remove element from base.
Wash element in detergent and hot water, then dry
thorou-ghly. Wipe all other components clean. Saturate
element with light oil. Squeeze firmly to evenly dis-
tribute oil and remove any excess.

walls and bearing surfaces in a stored engine. For max-
imum protection, prepare the engine for storage as
follows:

Run the engine until it reaches operating tempera-
ture. Stop the engine and drain the oil from
crankcase while engine is still warm.
