Grinding Wheel Use
Good grinding performance can only
be achieved using the correct and
constant rotational speed. To achieve
the best results when roughening,
apply the grinding disc to the grinding
surface at an angle of between 30°
and 40° and move evenly back and
forth over the workpiece. Do not
bend the grinding disc into the
cutting surface during cutting work.
W A R N I N G !
Do not use the cutting disc for
roughening work. Risk of fracture!
Use the tungsten carbide or chain
saw accessories.
