SYMBOLS Some of the following symbols may be used on this product. Please study them and learn their meaning. Proper interpretation of these symbols will allow you to operate the product better and safer. SYMBOL NAME DESIGNATION/EXPLANATION V Volts Voltage A Amperes Current Hz Hertz Frequency (cycles per second) W Watt Power Alternating Current Type of current no No Load Speed Rotational speed, at no load Class II Construction Double-insulated construction .../min Per Minute Revolutions, strokes, surface speed, orbits etc., per minute ELECTRICAL DOUBLE INSULATION EXTENSION CORDS Double insulation is a concept in safety in electric power tools, which eliminates the need for the usual three-wire grounded power cord. All exposed metal parts are isolated from the internal metal motor components with protecting insulation. Double insulated products do not need to be grounded. WARNING: The double insulated system is intended to protect the user from shock resulting from a break in the product's internal insulation. Observe all normal safety precautions to avoid electrical shock. When using a power tool at a considerable distance from a power source, be sure to use an extension cord that has the capacity to handle the current the product will draw. An undersized cord will cause a drop in line voltage, possibly resulting in overheating, loss of power, and/or circuit breaker or GFCI tripping. Use the chart to determine the minimum wire size required in an extension cord. Only round jacketed cords listed by Underwriter's Laboratories (UL) should be used. When working outdoors with a product, use an extension cord that is designed for outside use. This type of cord is designated with "WA" or "W" on the cord's jacket. NOTE: Servicing of a product with double insulation requires extreme care and knowledge of the system and should be performed only by a qualified service technician. For service, we suggest you return the product to your nearest authorized service center for repair. Always use original factory replacement parts when servicing. ELECTRICAL CONNECTION This product has a precision-built electric motor. It should be connected to a power supply that is nominal 120V/60Hz AC (typical U.S. household circuit). Do not operate this product on direct current (DC). A substantial voltage drop will cause a loss of power and the motor will overheat. If the product does not operate when plugged into an outlet, double-check the power supply. Before using any extension cord, inspect it for loose or exposed wires and cut or worn insulation. It is possible to tie the extension cord and power cord in a knot to prevent them from becoming disconnected during use. Make a knot, then connect the plug end of the power cord into the receptacle end of the extension cord. This method can also be used to tie two extension cords together. USE ONLY THIS SIZE EXTENSION CORD WHEN USING THIS PRODUCT: Cord Length 25 ft. 50 ft. 100 ft. Wire Size (A.W.G.) 14 12 Not Allowed NOTE: A.W.G. = American Wire Gauge 6 - English
