Cleaning of the W3 filter cartridge
1 Connect the compressed air supply.
2 Open the valve lever (1) at the compressed air connector (2).
The compressed air produces a dedusting jet and causes the dedusting nozzle to rotate inside the W3 filter cartridge.
NOTICE
• The cover of the air vent for cleaning (5) opens when compressed air is supplied. After cleaning, ensure that the cover
closes again, otherwise the suction power will be negatively impacted.
• The supplied air is directed via the bypass filter into the open air so that excess pressure does not build inside the filter
chamber.
