sage is displayed. The air filter is equipped with a
primary and a secondary element. As previously
stated, the Supervisor II will alert you as to when the
primary element maintenance is necessary. When
removing the primary element, always check the
secondary element for visible dirt, grease/oil, or
damage. The secondary element must be changed
after every sixth primary element inspection. DO
NOT clean the secondary element.
AIR FILTER ELEMENT REMOVAL
1. Clean exterior of air filter housing.
2. Remove the cover/element assembly by loosen-
ing the wing nut securing it.
3. Pull the cover/element assembly out of the hous-
ing.
4. On the inside of the element, you will notice a
lock ring, which fastens the cover to the ele-
ment. Remove the lock ring and pull the cover
and element apart.
5. Clean the interior of the housing by using a damp
cloth. DO NOT blow dirt with compressed air.
6. Inspect the secondary element and replace if
necessary. This element is NOT cleanable.
7. To remove the secondary element, unscrew the
secondary restriction indicator from the threaded
rod running through the element. Pull the ele-
ment out of the housing.
8. Install the new secondary element and replace
the restriction indicator.
9. With the secondary element in place, clean or
replace the primary element. Cleaning instruc-
tions follow.
ELEMENT INSPECTION
1. Place a bright light inside the element to inspect
for damage or leak holes. Concentrated light
will shine through the element and disclose 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 container.
4. After the element has been installed, inspect and
tighten all air inlet connections prior to resuming
operation.
PRIMARY ELEMENT REPLACEMENT
1. Place the element in position on the cover and
replace the locking to secure the cover and ele-
ment.
