English 5. Remove the tool from the work surface before turning the tool off. Allow the tool to stop rotating before laying it 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 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. Maintain a 5˚ to 10˚ angle between the tool and work surface. FIG. 11 4. Continuously move the tool in a forward and backward motion to avoid creating gouges in the work 5˚-10˚ surface. 5. Remove the tool from work surface before turning tool off. Allow the tool to stop rotating before laying it down. MOUNTING SANDING BACKING PADS (FIG. 12) CAUTION: Proper guard must be reinstalled for grinding wheel, sanding flap disc, wire brush or wire wheel applications after sanding applications are complete. 1. Place or appropriately thread backing pad (O) on the spindle. 2. Place the sanding disc (P) on the backing pad. 3. While depressing spindle lock, thread FIG. 12 clamp nut (H) on spindle, piloting the H P 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 pad while O depressing the spindle lock button. USING SANDING BACKING PADS (FIG. 13) Choose the proper grit sandpaper for your application. Sandpaper is available in various grits. Coarse grits yield faster material removal rates and a rougher finish. Finer grits yield slower material removal and a smoother finish. Begin with coarse grit discs for fast, rough material removal. Move to a medium grit paper and finish with a fine grit disc for optimal finish. Coarse 16 - 30 grit Medium 36 - 80 grit Fine Finishing 100 - 120 grit Very Fine Finishing 150 - 180 grit 1. Allow the tool to reach full speed before touching 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. Maintain a 5˚ to 15˚ angle between the tool and work surface. The sanding disc should contact approximately one inch of work surface. 15
