I would appreciate any advice on how to get my R4512 to stay heeled. I just purchased the table saw (my first Rigid tool) last weekend. Out of the box it was just a little off, so I followed the instructions in the manual. It took me probably 30 minutes to an hour to get it heeled. After making 3 or 4 cuts, I checked it and it was back out. I have tried it 2 more times and each time the same result. Is there something I am missing?
