Grinding wheels have the capability of
removing a lot of skin quickly. Keep a firm
grip on the dresser tool and holder and keep
your hands a safe distance away from the
spinning wheel.
3.
move the dresser tool so that the tip is just
outside the wheel's diameter, then turn the
grinder ON.
4. slowly move the dresser tool across the
wheel, then back to the starting position.
5. lower the table slightly and repeat Step 4.
Note: Several light passes with the dressing
tool will produce the best results, with the
least amount of wear or damage to the wheel
or the dressing tool. The fence will keep the
dressing tool from reaching the inside edge
of the wheel, which will leave a ridge at that
point. This will not affect the grinder's opera-
tion.
