1. Thread the wheel on the spindle by hand, seating the wheel against the soft mount. 2. Depress the spindle lock button and use a wrench to tighten the hub of the wheel. 3. Reverse the above procedure to remove the wheel. CAUTION: Failure to properly seat the wheel against the soft mount before turning the tool on may result in damage to the tool or the wheel. MOUNTING NON-HUBBED WHEELS Depressed center, Type 27 grinding wheels must be used with available accessory flanges. See the chart on pages 5–7 of this manual for more information. 10 399080-02 rev 11/15/02 10:13 AM Page 11 1. Install the metal backing flange (J) on spindle (E) against the soft mount. 2. Place wheel against the backing flange, centering the wheel on the backing flange pilot. 3. While depressing the spindle lock button, thread the clamp nut (K) on spindle, piloting the raised hub on clamp nut in the center of grinding wheel. 4. Tighten the clamp nut with a wrench. 5. Reverse the above procedure to remove the wheel. J E K SURFACE GRINDING WITH GRINDING WHEELS 1. Allow the tool to reach full speed before touching tool to work surface. 2. Apply minimum pressure to work surface, to allow the tool to operate at high speed. 3. Maintain a 20° to 30° angle between the tool and work surface. 20°- 30° 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 tool to stop rotating before setting it down. EDGE GRINDING WITH GRINDING WHEELS CAUTION: Wheels used for cutting and edge grinding may break if they bend or twist while the tool is being used to do cut-off work or deep grinding. To reduce the risk of serious injury, limit the use of these wheels with a standard Type 27 guard to shallow cutting and notching (less than 1/2" in depth). The open side of the guard must be positioned away from the operator. For deeper cutting with a Type 1 wheel, use a closed, Type 1 guard. Type 1 guards are available at extra cost from your local dealer or authorized service center. 1. Allow the tool to reach full speed before touching the tool to the work surface. 2. Apply minimum pressure to work surface, to allow the tool to operate at high speed. 3. Protect yourself during edge finishing by directing the open side of the guard away from you. 4. Move the tool continuously in a forward and back motion to avoid creating gouges in the work surface. 5. Remove tool from work surface before turning the tool off. Allow the tool to stop rotating before setting it down. WARNING: Do not use edge grinding wheels for surface grinding applications because edge grinding wheels are not designed for side pressures encountered with surface grinding. Wheel breakage and injury may result. SURFACE FINISHING WITH SANDING FLAP DISCS 1. Allow the tool to reach full speed before touching tool to work surface. 2. Apply minimum pressure to work surface, to allow the tool to operate at high speed. 3. Maintain a 5° to 10° angle between the tool and work surface. 5°- 10° 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 tool to stop rotating before setting it down. 11 English 399080-02 rev 11/15/02 10:13 AM Page 12 English Mounting and Using SandingBacking Pads Sanding pads and sanding discs must be rated above minimum accessory speed as shown on tool. Recommended sanding backing pads and sanding discs are available at extra cost from DEWALT service centers and DEWALT dealers. NOTE: Guard may be removed for sanding applications with backing pads and sanding discs. Sanding flap discs are considered grinding wheels by ANSI standards and require the use of a guard. (See Mounting and Using Depressed Center Grinding Wheels and Sanding Flap Discs). MOUNTING SANDING BACKING PADS Turn off and unplug tool before making any adjustments or removing or installing accessories. Before reconnecting the tool, depress and release the trigger switch to ensure that the tool is off. CAUTION: Proper guard must be re-installed for grinding wheel, sanding flap disc, wire brush, or wire wheel applications after sanding applications are complete. N USING SANDING BACKING PADS 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 coarser 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 work surface. 2. Apply minimum pressure to work surface, allowing tool to operate at high speed. 3. Maintain a 5° to 15° angle between the tool and work surface. The...
