surface for wire cup brushes.
4. Maintain contact between the edge of the wheel and
the work surface with wire wheels.
5. Continuously move the tool in a forward and back
motion to avoid creating gouges in the work surface.

to stop rotating before setting it down.
CAUTION:
Use extra care when working over an edge, as a sudden sharp
movement of grinder may be experienced.
