3. figure N - Maintain a 5˚ to 10˚ angle between the tool and work 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. Allowing the tool to rest on
the work surface without moving, or moving the tool in a circular
motion causes burning and swirling marks on the work surface.
6. Remove the tool from the work surface before turning the tool off.
Allow the tool to stop rotating before setting it down.
