I have a RS1000 and really enjoy using the saw. I bought it a couple years ago and plan to buy the TS3650 in about a month. However, I do seem to have a problem with the RS1000 and that is that when I swing the arm to a 45 degree cut and return it to center at 90 it is not square with the fence. Has any one had this problem? Or is it an adjustment problem. I have cut maybe a 100 board feet on the saw and don't use it a whole lot and don't rip on it. Any ideas?
