Installing Tool Rests TURN OFF POWER AND DISCONNECT FROM POWER SUPPLY. Hardware bags 5, 6, 7, and the remaining two knobs from bag #1 are used to assemble the tool rests. First install the left side tool rest brackets, as shown in Fig. 4. Next attach the tool rests. Use the bolts, washers, spacers and lock nuts from the plastic bag to secure the brackets and tool rests in place. NOTE: There is a left and right tool rest. When in actual use, the tool rests should be adjusted to within 1/8” of the grinding wheel or other accessory being used. CAUTION: Use the washers and screws supplied. Longer screws may interfere with the movement of the grinding wheel. Operation NEVER USE A BENCH GRINDER IF IT IS NOT FIRMLY FASTENED TO A WORK BENCH OR RIGID FRAME. Before turning the grinder on, put on safety glasses. Turn on the grinder and allow it to reach full speed (3500 RPM ). Hold the workpiece firmly and against the tool rest. Hold very small pieces with pliers or other suitable clamps. Feed the work smoothly and evenly into the grinding wheel. Move the work slowly and avoid jamming the work against the wheel. As the wheel tends to slow down you should occasionally release the pressure to let the wheel return to full speed. Grind only on the face of the grinding wheel and never on the side. (Some wheels are designed for side grinding and will say so on their instruction sheets). CAUTION: Prolonged grinding will cause most materials to become hot. Handle them with pliers. Switch The switch is located on the front of the grinder, on the base. (Figure 1) To turn the tool on depress the side of the rocker switch on the right side, marked “I”. To turn off the grinder, depress the left side of the rocker switch, marked “O”. Maintenance CLEANING Blowing dust and grit out of the wheel guards using compressed air is a necessary regular maintenance procedure. Dust and grit containing metal particles often accumulate on interior surfaces and could create an electrical shock hazard if not frequently cleaned out. ALWAYS WEAR SAFETY GLASSES. CAUTION: Never use solvents or other harsh chemicals for cleaning the non-metallic parts of the tool. Use clean, dry rag only. Accessories Recommended accessories for use with your tool are available at extra cost from your distributor or local service center. Grinding wheels must fit within the confines of the guard and must be rated higher than the recommended speed as marked on the nameplate. CAUTION: Strands of wire brushes may break and fly off while in use. Users and others in the area should wear adequate eye, face and body protection. Use only wire brushes that are rated at or greater than the RPM shown on the tool’s nameplate. The use of wire brushes is only recommended with the use of a spacer, Black & Decker part no. 791695-00. The spacer should be positioned behind the inner clamp washer toward the motor. To order the spacer call 1-800-54-HOW-TO (544-6986). Do not use the spacer with grinding wheels. WARNING: To reduce the risk of injury, always use proper guards when grinding and wear eye protection. CAUTION: The use of any non-recommended accessory may be hazardous. Changing Accessories TURN OFF THE TOOL AND DISCONNECT FROM POWER SUPPLY. CHANGE ACCESSORIES WHEN THE SPARK GUARD CAN NO LONGER BE ADJUSTED TO 1/16” FROM THE WHEEL. USE ONLY WHEELS THAT MEASURE 6” IN DIAMETER. THIS TOOL HAS 1/2” ARBORS ON BOTH SIDES. Follow the steps below to remove and replace an accessory. 1.Raise the eye shield up, and out of the way. 2.Loosen and pull the tool rest out as far as possible. Do not remove it. 3.Loosen and pull the spark guard out as far as possible, Do not remove it. 4.Remove the five screws from the side of the wheel cover and remove the cover. 5.Insert a flat bladed screwdriver into the slot in the left end of the grinder’s rotor shaft. Hold the screwdriver firmly to keep the shaft from turning as you loosen and remove the hex nut in the center of the grinding wheel or other accessory. NOTE: If you are changing only the right side accessory, you need not remove the left wheel cover. A hole in the center of the cover permits screwdriver insertion into the slotted shaft. Unscrew the nut in the center of the grinding wheel. It may be necessary to strike the wrench sharply in the loosening direction with the heel of your hand to loosen the nut. NOTE: The nut on the right side of the grinder has a standard right hand thread (turn counterclockwise to loosen). The one on the left side has a left hand thread (turn clockwise to loosen). 6.Remove the wheel washer and the wheel. 7. Inspect the wheel for cracks, chips or any other visible damage (other than normal wear) and discard if such damage is found. Inspect the blotters for damage. If the blotters are missing or severely damaged, replace them with pieces of thin cardboard or blotter paper cut in the same shape. NEVER USE A GRINDING WHEEL WITHOUT A BLOTTER ON EACH SIDE OF THE WHEEL. 8.Install the new wheel or other accessory. Be sure tha...
