Perform filter mat change as follows:
Open the louver grilles of the inlet filter (Fig. 25).
Remove the filter pad.
Insert the new filter pad into the louver grille. Ensure
that the smooth side (-A- Fig. 26) of the filter pad
faces the air inlet side.
Place the louver grille back onto the filter housing.
Changing times for the filter mat
The operating modes and the quality of the suctioned
air (e.g., dust content) has a strong influence on the
filter service life.
The filter should be checked on a weekly basis,
eventually daily basis, for dust build-up.
In these cases the intervals between changes may be
shorter.
