• Check it visually to make sure it is cle a n before
putting in a new element.
8. Check for uneven dirt patterns on your old element.
Your old element is a valuable clue to potential dust
leakage or gasket sealing problems. A pattern on the
element clean side is a sign that the old element was
NOT firmly sealed or that a dust leak exists.

• C heck the gasket for correct sizing. On a radial seal
element the gasket surface is the inside diameter of
the open end cap.

is not forming a perfect seal, you will NOT have
protection.

and the filter element is the correct model number.
