A reciprocating preferably transparent break guard is disclosed for use in connection with a reciprocating machine, such as a bending machine. Adjustable switching means are operatively associated with the machine for controlling the actuation of a hydraulic piston connected to a frame for the guard. When the machine is in its upper position for receiving a workpiece, the switching means causes the piston to be actuated to maintain the guard in its upper position free from interference with the break. When the machine is actuated and starts its downward stroke, the switching means actuates a solenoid to release the piston causing the guard to drop smartly in front of the break thereby preventing the operator from accidentally inserting hands or fingers into the break of the machine. In its lowered position, the machine again actuates the switching means to operate the piston to raise the guard to its upper position. The position of the lower edge of the break guard is adjustable relative to a workpiece receiving surface on the machine to admit a workpiece into the break while excluding the hand or finger of the operator from the break.
