I used to have an arm lift on my DeWALT saw. But soon I discovered it was just in the way. When I move from hole to hole, I let gravity lower the arm rather than having to pull the arm down. Also, when changing a new blade, there is no need to raise the arm at all. I simply insert the blade into the next hole in the work piece and line it up with the hole in the table, lower the blade to mount in the upper clamp, then the lower clamp. Easy, no need to raise the arm at all!
