MAINTENANCE (ENGINE)
ENGINE AIR CLEANER
1. Remove the air cleaner cover and foam filter element
as shown in Figure 26.
2. Tap the paper filter element (Figure 26) 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 air cleaner case
side.
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.
