5.Remove the tool from the work surface before turning the tool off. Allow the wheel to stop rotating before laying the tool down.

WARNING: Do not use edge grinding/cutting wheels for surface grinding applications because these wheels are not designed for side pressures encountered with surface grinding. Wheel breakage and serious personal injury may result.

SURFACE FINISHING WITH SANDING FLAP DISCS (FIG. 11)

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. Sanding rate is greatest when the tool operates at high speed.

3.While depressing the spindle lock button, thread clamp nut (P) on spindle, piloting the raised hub on the clamp nut into the center of sanding disc and backing pad.

4.Tighten the clamp nut by hand. Then depress the spindle lock button while turning the sanding disc until the sanding disc and clamp nut are snug.

5.To remove the wheel, grasp and turn the backing pad and sanding disc while depressing the spindle lock button.

USING SANDING BACKING PADS (FIG. 13)

Choose the proper grit sanding discs for your application. Sanding discs are available in various grits. Coarse grits yield faster material removal rates and a rougher finish. Finer grits yield slower material

3.Maintain a 5° to 10° angle between the tool and work surface.

4.Continuously move the tool in a forward and back motion to avoid creating gouges in the work surface.

5.Remove the tool from work surface before turning tool off. Allow the wheel to stop rotating before laying the tool down.
