Cleaning the dust evacuator valve:
The intake air is set into a rotating motion inside the filter housing. The resulting centrifugal forces
expel heavy dust particles outwards to the filter housing wall, where they are discharged via the
dust evacuator valve at the base of the housing.
Remove any dust build-up by squeezing the rubber lips of the valve together.
