grounded in accordance with all codes and ordinances. Never remove the grounding prong or modify the plug in any way. Do not use any adapter plugs. Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. If the tools should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user. 5. Double insulated tools are equipped with a polarized plug (one blade is wider than the other).
footing and balance enables better control of this product in unexpected situations. 14. Use safety equipment. Wear eye protection when assembling and using this product. TOOL USE AND CARE 15. Disconnect the Power Cord Plug from the power source before making any adjustments, changing accessories, or storing the Grinder/Buffer. Such preventive safety measures reduce the risk of starting the unit accidentally. 16. Store idle equipment out of reach of children and other untrained persons.
3. Maintain a safe environment. Keep the area well lit. Make sure there is adequate surrounding space. Always keep the area free of obstructions, grease, oil, trash, and other debris. Do not use an electrically powered product in areas near flammable chemicals, dusts, and vapors. 4. Never leave the Grinder/Buffer unattended when it is plugged into an electrical outlet. Turn off the Grinder/Buffer and unplug the tool before leaving. 5.
16. WARNING! Some dust created by power sanding, sawing, grinding, drilling, and other construction activities, contain chemicals known (to the State of California) to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement or other masonry products, arsenic and chromium from chemically treated lumber. Your risk from these exposures varies, depending on how often you do this type of work.
cord to the grounding system in the tool. The green wire in the cord must be the only wire connected to the tool’s grounding system and must never be attached to an electrically “live” terminal. (See Figure A.) 3. Your tool must be plugged into an appropriate outlet, properly installed and grounded in accordance with all codes and ordinances. The plug and outlet should look like those in the following illustration. (See Figure A.
EXTENSION CORDS 1. Grounded tools require a three wire extension cord. Double Insulated tools can use either a two or three wire extension cord. 2. As the distance from the supply outlet increases, you must use a heavier gauge extension cord. Using extension cords with inadequately sized wire causes a serious drop in voltage, resulting in loss of power and possible tool damage. (See Figure C.) 3. The smaller the gauge number of the wire, the greater the capacity of the cord.
SYMBOLOGY FIGURE D UNPACKING When unpacking, check to make sure all the parts shown on the Parts List on page 14 are included.

ASSEMBLY INSTRUCTIONS NOTE: For additional information regarding the parts listed in the following pages, refer to the Assembly Diagram on page 14. 1.
four mounting holes in the Base (15) of the machine as a template with which to mark four spots to drill mounting holes in the workbench. 3. Temporarily remove the Grinder/Buffer from the workbench. Drill the four mounting holes in the workbench. Set the Grinder/Buffer back on the workbench and align the machine’s mounting holes in its Base (15) with the four pre-drilled holes in the workbench. 4.
To Attach The Tool Rest: 1. Align the two mounting holes in the Tool Rest (30) with the two threaded mounting holes in the lower portion of the Wheel Guard (33). Secure the Tool Rest to the Wheel Guard, using two Washers (31) and two Hex Screws (32). 2. NOTE: Prior to tighten the two Hex Screws, the Tool Rest must be properly adjusted. The Tool Rest should be between 1/16” and 1/8” from the Grinding Wheel. Once adjusted, firmly tighten the two Hex Screws. (See Assy. Diagram.
4. Allow the Grinding Wheel (34) to spin up to full speed. 5. Place the workpiece you wish to grind on the Tool Rest (30), and slowly push the workpiece forward to make contact with the Grinding Wheel. Do not force the workpiece. Let the Grinding Wheel (34) grind at its own pace. Make sure to hold the workpiece firmly with both hands. 6. The workpiece will quickly become heated. Therefore, frequent immersing in water is required.
B. If you are using an “inline dresser”, hold the handle firmly. Place the dresser on the Tool Rest (30) so that its wheels can move freely (i.e., the exposed part of the wheel should be facing up). Let the Grinding Wheel reach full speed, and apply the dresser to all surfaces of the Grinding Wheel. INSPECTION, MAINTENANCE, AND CLEANING 1. WARNING! Make sure the Grinder/Buffer is disconnected from its electrical outlet prior to performing any inspection, maintenance, or cleaning procedures. 2.
