Engine Oil Recommendations
Oil is a major factor affecting performance and service life.
Use 4- stroke automotive detergent oil. SAE 10W-30 is
recommended for general use. Other viscosities shown in the
chart may be used when the average temperature in your
area is within the recommended range.
The SAE oil viscosity and service classification are in the API
label on the oil container. We recommended that you use
API SERVICE Category SE or SF oil.
6.13 Air Filter Inspection
Remove the air cleaner cover and inspect the filter.
Clean or replace dirty filter elements. Always
replace damaged filter elements. If equipped with
an oil-bath air cleaner, also check the oil level.
6.14 Air Filter Service
A dirty air filter restricts air-flow to the carburetor,
thereby reducing engine performance.
If you operate the engine in very dusty areas, clean
the air filter more often than specified in the
MAINTENANCE SCHEDULE.
6.14.1 Oil-Bath Type Air Filter
1. Remove the wing nut, and remove the air filter
cap and cover.
2. Remove the air filter from the cover, wash the
cover and filter in warm, soapy water, rinse, and
allow drying thoroughly. Or clean in
nonflammable solvent and allow drying.
3. Dip the filter in clean engine oil, and then
squeeze out all excess oil. The engine will smoke
if too much oil is left in the foam.
4. Empty the used oil from the air cleaner case, wash out any accumulated dirt with
nonflammable solvent, and dry the case.
