shown in Figure 23.

hard surface to remove dirt, or blow compressed air [not
exceeding 30 psi (207 kPa, 2.1 kgf/cm

brush off dirt.
Brushing will force dirt into the fibers. Replace the paper filter
element if it is excessively dirty.

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