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.

WARNING:
• When using an abrasive cut-off / diamond wheel,
be sure to use only the special wheel guard
designed for use with cut-off wheels.
• NEVER use cut-off wheel for side grinding.
• Do not "jam" the wheel or apply excessive pressure.
Do not attempt to make an excessive depth of cut.
Overstressing the wheel increases the loading and
susceptibility to twisting or binding of the wheel in
the cut and the possibility of kickback, wheel
breakage and overheating of the motor may occur.
• Do not start the cutting operation in the workpiece.
Let the wheel reach full speed and carefully enter
into the cut moving the tool forward over the
