Parkside PMNF 1500 A1 Wall Chaser Modification for Better Dust Extraction grooving cutter masonry 

I need to do same thing, did YOU Had problema with brushes?

Ne treba zatvarati otvor za promenu diska ,bar ne y potpunosti..... zato što se guši usisivač

👏👏👏👍🤙

Unfortunately, this modification does not seem reasonable to me. The pillar is there on purpose to protect the exhaust path, so that the home vacuum cleaner doesn't pull a big chunk of masonry. If you use an industrial vacuum cleaner, that's fine. But then again, you probably won't be using a cheap Parkside wall chaser.
