CLEANING THE PANEL FILTER
A thoroughly clean panel filter will ensure better machine vacuum system results, thereby reducing costs and
increasing environmental sustainability. To clean the panel filter, proceed as follows:
1. Stand at the back of the machine (with the machine switched off).
2. Remove the debris hopper by rotating the relative retainers (1) in the direction indicated by the printed arrows
(fig.1).
3. Turn the fixing pins (2) anti-clockwise to rotate the filter-holder frame (fig.2).
4. Rotate the filter-holder frame (4) to the maintenance position and take out the panel filter (3) (fig.3).
5. Clean the panel filter, carefully shaking it on a clean, flat surface. If necessary, clean with compressed air (≤
7atm), pointed in the opposite direction to the vacuum flow.
6. Reposition the panel filter on the filter-holder frame.
7. Rotate the frame back into its working position.

ATTENTION: remember to lift the manual filter shaker lever to let the filter-holder frame pass through.
8. Turn the fixing pins clockwise to lock the filter-holder frame.
9. Close the debris hopper by rotating the retainers in the direction indicated by the printed arrows.
N.B.: pay attention to the working direction of the panel filter when inserting it in the vacuum compartment on
the machine: the gasket in the filter must be in contact with the machine frame.
