~ Inner Element
The inner element should be checked for restriction whenever the outer
element is serviced. After the outer element has been cleaned or a new element
installed, start the engine and run at full throttle and observe the restriction
indicator. If the red band moves into the indicator window, replace the inner
element.
Element Service
Cleaning the inner element is not recommended except in an emergency.
If the element is cleaned, it must be replaced as soon as possible. Maximum
engine protection is achieved by replacing the restricted element with a new
element.

Cleaning the Outer Element with Compressed Air
The element can also be cleaned with compressed air, using a maximum of
30 psi (207 kPa) at the nozzle. Keep the air nozzle a reasonable distance from
the fi Iter element. Use of compressed air is not always recommended because
it will not remove carbon and soot like washing.
NOTE: Never attempt to clean the element by rapping. Rapping the
element will dent the metal covering. The inner paper element will in turn rub
this dent, causing the element to puncture.
