In general, keep the edge of-the depressed
center wheel a t an angle of about 1 5 O in
relation to the workpiece surface.
.During the break-in period with a new
grinding wheel, do not work the grinder
in the B direction or
it
will cut into the
material. Once the edge of the wheel has
been rounded off by use, the wheel may
be worked in both A and B directions.
.Check for cracks in the depressed center wheel and for loose or missing screws.
.Always use the guard. It can prevent an accident if a wheel should ever break.

Choose a wheel grit in terms of the workpiece material.
.Before using the disc grinder on an actual workpiece, let it simply run for several minutes
first. Watch for flutter that might be.caused by poor installation or a poorly balanced
wheel.
.Bring the depressed center wheel into gentle contact with the work surface.
Do
not bear
down as this will slow the wheel revolution, make for a poor finish, and the load on the
motor will cause undue wear.

Maintenance
