This saw did not operate out of the box. I took it into a Dewalt repair shop and they first replaced the speed control, which did not correct the problem. Then they replaced the printed circuit board and I had a working saw. Working for about one hour of use that is. The saw again does not have any speed control. You turn the saw "on" and whatever speed is present is what you get. Not looking forward to making continuous trips into Denver trying to get my monies worth out of this thing. Highly disatisfied. I thought DeWalt was above Black and Decker quality. I was wrong.
