8. Inspect the new filter(s) for damage by looking into
the filter while shining a bright light on the outside
of the filter. Holes in the filter will appear as bright
spots. Inspect the element for tears, an oily film, or
damage to the rubber seal. If the filter is damaged
do not use it.

the new filter into the filter body (Figure 30).
Important: To prevent engine damage, always
operate the engine with both air filters and cover
installed.

(Figure 30). Ensure that it is fully seated by pushing
on the outer rim of the filter while installing it.

of the filter.
