Perform filter mat change as follows:

Open the louver grilles of the inlet filter (Fig. 23).

Remove the filter pad.

Insert the new filter pad into the louver grille. Ensure that the smooth side (-A- Fig. 24) 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.
