I just picked up the Festool FS-WA and it won’t stay clipped onto the rail, it appears that the rubber is too thick. I clip it on and if I hold it down it will stay on and if I let go it just slips off. I called Festool and they were no help other than to tell me to return it which I will probably do, just seems kind of silly if that little rubber piece could just be replaced plus there aren’t any in stock locally. Anyone else seen this, it would be helpful if they sent a small manual out with it. Thanks
