disc
at an angle of about 15" to the work-
piece 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 Bdirections.

0 It should never be necessary to force the tool. The weight of the tool applies adequate
pressure. Forcingand excessive pressurecould cause dangerous wheel breakage.
.Continued use
of a worn-out wheel may result in wheel explosion and serious personal
injury. Depressed center wheel should not be used after
it has been worn down to
115 mm (4-1/2") in diameter. Use of the wheel after this point is unsafeand it should
be removed from service and rendered unusable by intentional destruction.
