Maintenance
Never blow dirt out of the interior of the filter housing. This
may introduce dust downstream of the filter. Instead, use a
clean damp cloth.
Do not strike the element against any hard surfaces for clean-
ing as it may possibly rupture the element. Do not oil element.
When cleaning an element, the element will be damaged if you
exceed the recommended maximum air pressure of 30 PSI.
