ENGINE AIR CLEANER
1. Remove the air cleaner cover and foam filter element as
shown in Figure 21.
2. Tap the paper filter element (Figure 21) several times on a
hard surface to remove dirt, or blow compressed air [not
exceeding 30 psi (207 kPa, 2.1 kgf/cm

)] 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.
