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.

that the maintenance area is well ventilated. Gasoline engine exhaust contains poisonous carbon monoxide gas that can cause unconsciousness and may result in DEATH

General Cleanliness

Clean the trowel daily. Remove all dust and slurry buildup. If the trowel is steam-cleaned, ensure that lubrication is accomplished AFTER steam cleaning.

Engine check

Check daily for any oil and/or fuel leakage, thread nut and bolt tightness, and overall cleanliness.
