A load-bearing structure of a motor vehicle, having hollow profiles and junction elements to connect the hollow profiles. A barrier wall is disposed to hold back dust flying during sanding action to permit the dust to fall into a dust passageway in a dust collecting member. The first feed path bypasses a workpiece mover of the cutter. Alternatively, the driver may be a light emitting diode or any other diode with a different material and die size than the LED, connected to the bipolar transistor to create a low voltage clamping device. A specification of the Web view is then stored in a file.
