ALWAYS hold the tool firmly with one hand on rear
handle and the other on the side handle. Turn the tool on
and then apply the wheel or disc to the workpiece.
In general, keep the edge of the wheel or disc at an
angle of about 15 degrees to the workpiece surface.
During the break-in period with a new wheel, do not work
the grinder in the B direction or it will cut into the
workpiece. Once the edge of the wheel has been
rounded off by use, the wheel may be worked in both A
and B direction.
