[. . . ] A moment of inattention while operating power tools may result in serious personal injury. Double insulated tools are equipped with a polarized plug (one blade is wider than the other. Double insulation eliminates the need for the three wire grounded power cord and grounded power supply system. Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. [. . . ] Table 1 shows the correct size to use depending on cord length and nameplate ampere rating. DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to sander safety rules. If you use this tool unsafely or incorrectly, you can suffer serious personal injury. Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord. Contact with a "live" wire will make exposed metal parts of the tool "live" and shock the operator. This tool has not been waterproofed, so do not use water on the workpiece surface. Ventilate your work area adequately when you perform sanding operations. Use of this tool to sand some products, paints and wood could expose user to dust containing hazardous substances.
