The positive stops on my brand new Makita XSH06 for 45 degree and for 56 degrees are fine. However, the positive stop for 22.5 degrees stops shy at about 20 degrees. 2.5 degrees inaccurate. I've looked long and hard at it and I can't see anything blatantly wrong with the positive stopping device. Does anyone else see this flaw in their 7 1/4" Makita circular saw?
