Operation (Fig. 7)
Keep the edge of the wheel or disc at an angle of
about 15° – 30° to the workpiece surface. During the
break-in period with a new wheel, do not work the tool
in the B direction. 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 directions.
Warning:
• It should never be necessary to force the tool. The
weight of the tool applies adequate pressure. Forc-
ing and excessive pressure could 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 75 mm for Model 9520NB or
90 mm for Models 9521NB and 9522NB in diam-
eter.
