Here's the problem I encountered with my new PM saw as well as the one on display at the place of purchase. This can easily be fixed if you re drill the holes to move the rail up. Once you hit the rail there is so much leverage that it will throw the arbor alignment way off. Once that happens it's difficult to realign it. PM replaced my saw when this happened to mine. When I got the new one I tilted it before I attached the fence and it was fine. Then when I had the fence on it happened again. That's when I figured out it was the angle iron from the back side of the fence. It doesn't happen until you hit 40 degrees. I hope this helps anyone with this issue.
