Abstract: A safety system for a power miter saw comprises a support member, at least one multidirectional manipulator including a workpiece holder member moveably mounted to the support member for securing a workpiece in place, and a control box. The workpiece holder member includes a presence indicator operatively connected to the control box and configured to detect the physical presence of a saw operator's hand on the at least one multidirectional manipulator when the saw operator's hand engages the presence indicator. The control box is operatively connectable to a trigger switch of the power miter saw so that an electric motor of the power miter saw is activated only when both the presence indicator of the safety system and the trigger switch of the power miter saw are engaged by both hands of an operator of the power miter saw.
