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 container.

•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

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

•Drain the engine oil.

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

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

•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.

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

•Start the engine and check for oil filter leaks.

•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 oper- ating the engine in extremely dusty areas.

WARNING

Never use gasoline or low flash point solvents for cleaning the air cleaner element. A fire or explo- sion 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.

Engine

Air Pre-cleaner Service

•Loosen the cover retaining knob and remove the cover.

•Remove the pre-cleaner from the paper element.

•Wash the pre-cleaner in warm water with detergent. Rinse the pre-cleaner thoroughly until all traces of detergent are eliminated. Squeeze out excess water (do not wring). Allow the pre-cleaner to air dry.

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

•Reinstall the pre-cleaner over the paper element.

•Reinstall the air cleaner cover. Secure cover with the cover retaining knob.
