cleaner cover off of the air cleaner body (Figure 40).
5. Clean the inside of the air cleaner cover with
compressed air.
6. Gently slide the primary filter out of the air cleaner
body (Figure 40). Avoid knocking the filter into the
side of the body.
7. Remove the safety filter only if you intend to replace
it.
Important: Never attempt to clean the safety
filter. If the safety filter is dirty, then the primary
filter is damaged and you should replace both
filters.
8. Inspect the primary filter 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. If the filter is damaged discard it.
