tenance indicator shows red. The maintenance indi-
cator is located on the filter outlet. The air filter is
equipped with a primary element and a secondary
element. As previously stated, the restriction indica-
tor will alert you as to when primary element mainte-
nance is necessary. When removing the primary
element, always check the secondary element for
visible dirt, grease or damage. The secondary ele-
ment must be changed after every third element
change or once a year, whichever comes first.
DO NOT
reconnect the secondary element once it is
removed.
ELEMENT REMOVAL
1. Clean the exterior of the air filter housing.
2. Remove the cover assembly by loosening the
wingnut securing the cover clamp.
3. Remove the element assembly from the housing
by unscrewing the wingnut.
4. Clean the interior of the housing by using a damp

secondary restriction indicator from the threaded
rod running through the element. Pull the ele-
ment out of the housing.
7. Install the new secondary element and replace
the restriction indicator.
8. With the secondary element in place, replace the
primary 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 and disclose any
holes.
2. Inspect all gaskets and gasket surfaces of the
housing. Should faulty gaskets be evident, cor-
rect 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 re-
place the lockring to secure the cover and ele-
ment.
2. Install the cover/element assembly and replace
the wingnut. Tighten the wingnut so to fully seat
