5. Loosen and remove the hex nut securing the
secondary element. Remove the secondary ele-
ment.
6. Inspect the secondary element and replace if
necessary.
7. Clean the interior of the housing by using a damp
cloth. DO NOT blow dirt out with compressor air.
8. Install the new secondary element and replace
the sealing washer and hex nut.
9. With the secondary element in place, replace the
primary element.
DO NOT strike the element against any hard sur-
face to dislodge dust. This will damage the sealing
surfaces and possibly rupture the element.
DO NOT “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 oil the element.
ELEMENT INSPECTION
1. Place a bright light inside the element to inspect
for damage or leak holes. Concentrated light will
shine through the element, revealing any holes.
2. Inspect all gaskets and gasket contact surfaces
of the housing. Should faulty gaskets be evi-
dent, correct the condition immediately.
3. If the clean element is to be stored for later use, it
must be stored in a clean, closed container.
4. After the element has been installed, inspect and
tighten, if necessary, all air inlet connections
prior to resuming operation.
PRIMARY ELEMENT REPLACEMENT
1. Place the element in position over secondary ele-
ment. Replace the sealing washer and wingnut.
Tighten the wingnut so as to fully seat the ele-
ment gasket.
2. Install the cover/element assembly and replace
the wingnut.
