Changing oil (Fig. 27)

Note: Dispose of used motor oil in an environmentally friendly manner. We suggest you drain used

oil into sealed containers and take them to your local service for reclamation. Do not throw the

sealed container in the trash or pour used oil on the ground.

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

• Remove the oil filler cap and drain the oil.

• Refill with the recommended oil and check the level.

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

Air filter cleaning

Warning: Never use gasoline or low flash point solvents for cleaning the air cleaner element, otherwise, a fire or explosion could result.

Caution: Never run the engine without the air cleaner. Rapid engine wear will be the result.

• Remove the wing nut and the air cleaner cover. Remove the elements and separate them. Carefully check both elements for holes or tears and replace if

damaged.

• Foam element: Clean in warm soapy water, rinse and allow to dry thoroughly or clean in high flashpoint solvent and allow to dry. Dip the element in clean

engine oil and squeeze out all the excess. The engine will smoke during initial start-up if too much oil is left in the foam.

• Paper element: Tap the element lightly several times on a hard surface to remove excess dirt or blow compressed air through the filter from the inside out.

Never try to brush the dirt off.

Fuel filter (Fig. 28)

• Turn the fuel valve to the OFF position and remove the fuel filter and the O-ring.
