CAUTION

ALWAYS allow the engine to cool before servicing. NEVER attempt any maintenance work on a hot engine.

CAUTION

ALWAYS disconnect the spark plug wire from the spark plug and secure away from the engine before performing maintenance or adjustments on the machine.

Engine Air Cleaner

DANGER

DO NOT use gasoline or low flash point solvents for cleaning the air cleaner, the possibility exists of fire or explosion which can cause damage to the equipment and severe bodily harm or even DEATH!

CAUTION

Wear protective equipment such as approved safety glasses or face shields and dust masks or respirators when cleaning air filters with compressed air.

This engine is equipped with a replaceable, high-density paper air cleaner element. See Figure 42 for air cleaner components.

1.Remove the air cleaner cover and foam filter element.

2.Tap the paper filter element several times on a hard surface to remove dirt, or blow compressed air not exceeding 30 psi (207 kPa, 2.1 kgf/cm2) through the filter element from the inside out. NEVER brush off dirt. Brushing will force dirt into the fibers. Replace the paper filter element if it is excessively dirty.

3.Clean foam element in warm, soapy water or nonflammable solvent. Rinse and dry thoroughly. Dip the element in clean engine oil and completely squeeze out the excess oil from the element before installing.
