EnGLIsh
The machine must always work in an upgrinding motion.
Otherwise, the danger exists of it being pushed uncontrolled
out of the cut.
When cutting profiles and square bar, it is best to start at the
smallest cross section.
Rough Grinding

always use the guard type 27.
The best roughing results are achieved when setting the
machine at an angle of 30° to 40°. Move the machine back and
forth with moderate pressure. In this manner, the workpiece
will not become too hot, does not discolour and no grooves
are formed.
Cutting Stone
The machine shall be used only for dry cutting. For cutting
stone, it is best to use a diamond cutting disc. Operate the
machine only with additional dust protection mask.
