AIR FILTER MAINTENANCE
Refer to Figure 7-2. Air filter maintenance should
be performed when the air filter maintenance mes-
sage is displayed. The air filter is equipped with a
primary element and a secondary element. As pre-
viously stated, the Supervisor will alert you as to
when the primary element maintenance is neces-
sary. When removing the primary element, always
check the secondary element for visible dirt, grease
or damage. The secondary element must be
changed after every sixth primary element change.
DO NOT clean the secondary element.
ELEMENT REMOVAL
1. Clean the exterior of the air filter housing.
2. Remove the cover assembly by loosening the
wingnut securing it.
3. Pull the element assembly out of the housing.
4. On the inside of the element, you will notice a
wingnut which fastens the element to the hous-
ing. Remove the wingnut and pull the element
out.
5. Clean the interior of the housing by using a damp
cloth. DO NOT blow dirt out with compressor air.
6. Place the replacement element into position.
Replace the sealing washer and wingnut.
Tighten the wingnut so as to fully seat the ele-
ment gasket.
7. Install the cover/element assembly and replace
the wingnut.
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.
