Perform filter mat change as follows:
•
Open the louver grilles of the inlet filter (Fig. 27).
•
Remove the filter pad.
•
Insert the new filter pad into the louver grille. Ensure
that the smooth side (-A- Fig. 28) 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.
