An electrically powered rotary hammer includes a first switchable gear arrangement for actuating the hammering mechanism and a second switchable gear arrangement for actuating the rotary drive mechanism. The image pickup apparatus comprises a sound output section, and an operating member for operating the image pickup apparatus. The punching defines a first gas channel extending through a first end, and a mounting hole and a number of suction holes extending through a second end. The first embodiment uses a locking mechanism in the actuator to prevent the actuator from turning past the parking lights and headlights position. The power circuit is directly connected to the output of the interface circuit.
