Abstract
A new and unique device for determining a correct sawing position for a portable rotary sawing machine is disclosed which has a rectangular opening or watching window provided on the front part of a stationary protective cover so that an operator clearly watches a rotary saw therethrough. An alignment is ensured for the intended correct sawing operation by watching the rotary saw, indicator gauge and scribing line on a workpiece to be sawn. The rectangular opening or watching window is removably closed with a transparent cover plate. According to other aspect of the invention the device is constructed such that the intended alignment is achieved by watching an indicator line or holes, indicator gauge and scribing line on a workpiece, said indicating line or holes being provided on the front part of the stationary protective cover in the peripheral direction. Further, according to another aspect of the invention the whole stationary protective cover or a part thereof is constructed of transparent material so that he clearly watches the rotary saw at a glance. The required alignment is ensured by watching a straight line extending through the rotary saw, indicator gauge and scribing line on a workpiece, while he holds the rotary sawing machine in front of the workpiece.
