Miter saw with improved safety system
A miter saw is disclosed having a base, a blade supported by the base, a detection system adapted to detect contact between a person and the blade, and a reaction system associated with the detection system to cause a predetermined action to take place upon detection of the dangerous condition. The blade is rotatable, and moves into a cutting zone to cut a workpiece. The predetermined action may be to stop the blade from rotating.
