Page 2: Instructions And Warning-Electric Devices
IMPORTANT INSTRUCTIONS AND WARNING - Electric Devices WARNING! When using electric tools, basic safety precautions should always be followed to reduce the risk of fire, electrical shock and personal injury, including the following. Read all these instructions before operating this product and save these instructions. GROUNDING INSTRUCTIONS 1. In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool is equipped with an electric cord with a grounding conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordnances. 2. Don't modify the plug provided - if it will not fit the outlet, have the proper outlet installed by a qualified electrician. 3. Improper connection of the grounding conductor can result in electric shock. The conductor with insulation having an outer surface that is green with or without yellow stripes is the grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the grounding conductor to a live terminal. 4. Check with a qualified electrician or service person if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded. 5. Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the tool's plug. 6. Repair or replace damaged or worn cord immediately. 7. This tool is intended for use on a circuit that has an outlet that looks like the one illustrated in Sketch A in Figure (below)(115V). The tool has a grounding plug that looks like the plug illustrated in Sketch A in Figure (below). A temporary adapter, which looks like the adapter illustrated in Sketches B and C, may be used to connect this plug to a 2-pole receptacles as shown in Sketch B if a properly grounded outlet is not available. The temporary adapter should be used only until a properly grounded outlet can be installed by a qualified electrician. The green-colored rigid ear, lug, and the like, extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box.
