CLEAN CAB RECIRCULATION FILTER
To clean:
1. Remove the two retaining screws, 1, from the
cover, 2.
2. Remove the cover and filter, 3.
3. Soak the filter for 15 minutes in warm water
containing a mild detergent.
4. Rinse the filter with running water below 1.4 bar
(20 PSI).
5. Shake off the excess water and allow to air dry.
IMPORTANT: Do not attempt to dry the filter with
heat or compressed air and do not install until
thoroughly dry as the filter may rupture. It is
recommended that a new filter is installed at this
service and the washed one put aside for installation
at a subsequent service. Store the spare filter in a dry
place and wrap it to prevent dust contamination or
damage.
6. Install the filter, cover and retaining screws.
NOTE: Wash the filter more frequently when
operating in extremely dusty conditions.
IMPORTANT: Replace the filter when holes or tears
are visible.
