Figure 32. Engine Air Cleaner
DO NOT use gasoline as a cleaning
solvent, because that would create a risk
of fire or explosion.
Engine Air Cleaner
1. Remove the air cleaner cover and foam filter element as
shown in Figure 34.
2. Tap the paper filter element (Figure 32) several times on
a hard surface to remove dirt, or blow compressed air
[not exceeding 30 psi (207 kPa, 2.1 kgf/cm

filter element from the air cleaner case side. NEVER
brush off dirt. Brushing will force dirt into the fibers.

mable solvent. Rinse and dry thoroughly. Dip the element
in clean engine oil and completely squeeze out the
excess oil from the element before installing.

Figure 31.
