I have discovered that I am not to increase the blade tention. The dewalt service center said it is a a adjustment which works, but stop after a while. The have told me how to adjust it, but never why. From further investigation I discovered that when changing blades is the arm is raise while the tention adjustment is set it loosed its setting. I have looked at the parts diagram, but do not understand why it looses the setting. Could anyone send me more information. I have found documents on the internet on how to adjust it, but nothing seem to tell you why or how this is happening.
thanks,
