2. Hold the primary air cleaner element (5),
shake it slightly and turn it in both direc-
tions in order to pull it out.
3. After removing the primary air cleaner ele-
ment (5), check the secondary air cleaner
element to see if it displaces or tilts. Push
it back to position in case of displacement
or tilting.
4. After removal of the primary air cleaner
element (5), use clean cloth or tape to
cover the secondary air cleaner element (6)
in order to prevent entering of dirt.
5. Wipe or brush off the dirt from the cover (3)
and the inside of air cleaner housing (1).
6. Wipe off the dirt built up on the cover (3)
and the vacuum valve (4).
7. Use dry compressed air (less than 0.69
MPa (7kgf/cm2) 99.4 PSI)) to blow along
the inside of the pleats toward the primary
air cleaner element, and then direct the
compressed air along the outside of the
pleats to blow from interior to exterior.
1) Replace the primary air cleaner ele-
ments that have been cleaned six times
or used for more than a year. Replace
the secondary air cleaner element at the
same time.
2) Remove one of the tags from the filter
after each cleaning.
