5. Remove the primary element and inspect it. If it
appears damaged in any way, replace it. If the ele-
ment is heavily soiled, replace it. If it appears to be
in good condition, clean if necessary and re-install.
6. Once the primary element has been removed, the
secondary element (C) should be visible. Remove
and inspect it. If the element is damaged or heavi-
ly soiled replace it.
Note: The secondary element is not serviceable. It should be
replaced after every three cleanings of the primary filter.
Note: The primary element may be cleaned and reused up
to five times if properly maintained, but should be replaced at
least once a year.
7. Once the inspection has been performed, install
the new secondary filter element into the enclo-
sure as found upon disassembly.
8. To ease installation, insert the primary element into
the cover and then install the cover/primary ele-
ment assembly by sliding it into place in the enclo-
sure as found upon disassembly.
9. Then secure the cover by turning it clockwise
approximately 1/8 turn and pushing the yellow
slide lock in until flush with the outside of the
cover.
To clean your primary filter element:
1. Remove loose dirt from the filter element with com-
pressed air or water hose.
- Compressed air: 100 P.S.I. (690 kPa) max. 1/8"
(.32 cm) diameter nozzle at least 2" (5.1 cm)
away from filter.
- Water: 40 psi (275.5 kPa) max. without
nozzle.
2. Soak the filter in a non-sudsing detergent solution
for at least 15 minutes moving it gently through the
solution to further clean the element. (Never soak
for more than 24 hours.)
3. Rinse the filter thoroughly with a gentle stream of
water to remove all dirt and remaining detergent.
4. Allow the filter to dry completely before rein-
stalling it into the PT-100 Forestry.
Do not use any heat source other than warm air at less than
160°F (71C) to dry the filter.
Do not clean air filter elements while engine warranty is in
effect. During the warranty period, Terex recommends
replacing air filter elements instead of cleaning them. Heavy-
duty air filter manufacturers will not warrant the air filter once
it has been cleaned.
