CharleyL Posted February 4, 2017 Report Share Posted February 4, 2017 (edited) I don't hold the upper arm down on my DeWalt 788 when tensioning, but I do put some downward pressure on it when tightening the blade clamp, just to get all of the slack out of the mechanism. For tensioning,Before locking in the blade, the tension lever needs to be set to zero. After tightening the blade clamps then tension the blade. I almost always set it to 3.5 - 4 Anything less, and the blade doesn't stay straight enough for what I do, which is mostly compound (3D) cutting.

Jim McDonald Posted February 6, 2017 Report Share Posted February 6, 2017 I had to have some service done to DeWalt a few years ago and when I got it back, the tension was not right. So I gave the rod in the back a couple of turns and now I pretty much max out on what the blade holders will handle at about 3.5. Quote Link to comment Share on other sites More sharing options...
