Abstract:
A power tool safety device for a power tool having a table defining a working surface, a cutting tool disposed adjacent the working surface with at least a portion of the cutting tool extending above the working surface and a guard moveably disposed adjacent the working surface, the guard covering the at least a portion of the cutting tool extending above the working surface, the safety device comprising:a proximity detector detecting a predetermined relative proximity between the guard and the working surface; and an interlock system coupled to the proximity detector and responding to the detecting of the predetermined relative proximity by the proximity detector, the interlock system preventing use of the power tool when the proximity detector does not detect the predetermined relative proximity between the guard and the working surface and enabling use of the power tool when the proximity detector does detect the predetermined relative proximity between the guard and the working surface.
