USING WIRE CUP BRUSHES AND WIRE WHEELS (FIG. 14) Wire wheels and brushes can be used for removing rust, scale and paint, and for smoothing irregular surfaces.
NOTE: The same precautions should be taken when wire brushing paint as when sanding paint (refer to Precautions To Take When Sanding Paint).
1.Allow the tool to reach full speed before touching the tool to the work surface.
2.Apply minimum pressure to work surface, allowing the tool to operate at high speed. Material removal rate is greatest when the tool operates at high speed.
3.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 | FIG. 14 |
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.
CAUTION: Use extra care when working over an edge, as a sudden sharp movement of grinder may be experienced.

CAUTION: Failure to properly seat the wheel against backing flange before turning the tool on may result in damage to the tool or the wheel.
NOTE: Adjust the guard skirt so that only 1/8" (3.17 mm) of the wheel is exposed by loosening the bolts, allowing the guard to lengthen. Tighten the guard skirt bolts securely before using the grinder.
