<p>The object of the invention is to provide a completely safe protection device which is very easy to handle and, on account of aerodynamic profiles in its interior, produces very good dust removal at a low suction power. With additional fittings, it is possible to constantly visually monitor the cutting by means of transparent structural parts and to have a better view of the cutting by means of one or more illumination arrangements. The optically active parts are easy to exchange. <IMAGE></p> |
