USING CUTTING WHEELS
WARNING: Do not use edge grinding/ cut- ting wheels for surface grinding applications because these wheels are not designed for side pressures encountered with surface grinding. Wheel breakage and injury may result.
1. Allow tool to reach full speed before touching tool to work surface.
2. Apply minimum pressure to work surface, allowing tool to operate at high speed. Cutting rate is greatest when the tool operates at high speed.
3.Once a cut is begun and a notch is established in the work- piece, do not change the angle of the cut. Changing the angle will cause the wheel to bend and may cause wheel breakage.
4.Remove the tool from work surface before turning tool off. Allow the tool to stop rotating before setting it down.
