4. Clean the inside of the cleaner housing

NOTE:
Clean the seal tube in the cleaner housing.
Dust on the seal tube causes dust leak.

can be cleaned with
compressed air 200 kPa (2 kgf/cm
2
) maximum.
Direct air along pleats inside of filter element.
6. Inspect the filter element after cleaning. Do not
use a filter element with damaged pleats, gasket
or seats.
NOTE:
The used element may be useful to find a
foreign substance on the seal surface of the filter
element, which can cause leak. If the striped dust
is seen on the seal surface, it is a symptom of dust
leak. If such dust seen, inspect if there are foreign
substances, on the inside and outside of the
housing seal tube.

element. To seal the element more accurately, push
securely not the center but the outer of the element
end surface.
