ENGINE OIL CHANGE

Drain the oil while the engine is warm to assure rapid and complete draining.

•Remove the oil filler cap and dipstick. Remove the yellow cap from the oil drain valve and attach the flexible drain tube supplied with the machine. Push in and twist the drain valve counterclockwise. Pull the valve out and drain the oil into a suitable contain- er.

•Close the drain valve by pushing in and twisting clockwise. Replace the yellow cap.

•Refill to the upper limit mark on the dipstick with the recommended oil. Tighten the oil filler cap securely.

ENGINE OIL REFILL CAPACITIES

Without oil filter replacement:

•1.7 US qt. (1.4 Imp qt., 1.6 liter)-Kohler

•1.5 US qt. (1.2 Imp qt., 1.4 liter)-Onan P220 OHV

With oil filter replacement:

•2.0 US qt. (1.7 Imp qt., 1.9 liter) -Kohler

Use 4-stroke motor oil that meets or exceeds the requirements for API service classification SG or SH. Always check the API SERVICE label on the oil con- tainer to be sure it includes the letters SG or SH.

SAE 10W-30 is recommended for general, all-temper- ature use, -5 F to 104 F (-20 C to 40 C). For the Onan engine, it is recommended that SAE 30 oil be used above 82 F (27 C).

See Engine Owner’s Manual for more specific infor- mation on oil viscosity recommendations.

Wash your hands with soap and water after handling used oil.

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 sta- tion or recycling center for reclamation. Do not throw it in the trash, pour it on the ground or down a drain.

OIL FILTER CHANGE

1.Drain the engine oil.

2.Remove the oil filter, and drain the oil into a suitable container. Discard the used oil filter.

3.Clean the filter mounting base, and coat the gasket of the new oil filter with clean engine oil.

4.Screw on the new oil filter by hand, until the gasket contacts the filter mounting base, then use an oil fil- ter socket tool to tighten the filter an additional 1/2 to 7/8 turn.

5.Refill the crankcase with the specified amount of the recommended oil. Reinstall the oil filler cap.

6.Start the engine and check for oil filter leaks.

7.Stop the engine, and check the oil level. If neces- sary, add oil to the upper limit mark on the dipstick.

AIR CLEANER SERVICE

A dirty air cleaner will restrict air flow to the carbure- tor. To prevent carburetor malfunction, service the air cleaner regularly. Service more frequently when operating the engine in extremely dusty areas.

WARNING

•Never use gasoline or low flash point solvents for cleaning the air cleaner element. A fire or explosion could result.

CAUTION

•Never run the engine without the air cleaner. Rapid engine wear will result from contaminants, such as dust and dirt being drawn into the engine.

4.Saturate the pre-cleaner with new engine oil. Squeeze out all excess oil.

5.Reinstall the pre-cleaner over the paper element.
