ELECTRICAL DOUBLE INSULATION Double insulation is a concept in safety in electric power tools, which eliminates the need for the usual threewire grounded power cord. All exposed metal parts are isolated from the internal metal motor components with protecting insulation. Double insulated tools do not need to be grounded. WARNING: Keep the extension cord clear of the working area. Position the cord so that it will not get caught on lumber, tools, or other obstructions while you are working with a power tool. Failure to do so can result in serious personal injury. WARNING: The double insulated system is i­ntended to protect the user from shock resulting from a break in the tool's internal insulation. Observe all normal safety precautions to avoid electrical shock. 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 120 volts (AC only normal household current), 60 Hz. 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. EXTENSION CORDS 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, resulting in overheating and loss of power. 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. Before using any extension cord, inspect it for loose or exposed wires and cut or worn insulation. **Ampere rating (on product data plate) 0-2.0 2.1-3.4 3.5-5.0 5.1-7.0 7.1-12.0 12.1-16.0 Cord Length Wire Size (A.W.G.) WARNING: Check extension cords before each use. If damaged replace immediately. Never use the product with a damaged cord since touching the damaged area could cause electrical shock resulting in serious injury. GROUND FAULT CIRCUIT INTERRUPTER See Figure 1, page 15. This unit is equipped with a Ground Fault Circuit Interrupter (GFCI), which guards against the hazards of ground fault currents. An example of ground fault current is the current that would flow through a person who is using an appliance with faulty insulation and, at the same time, is in contact with an electrical ground such as a plumbing fixture, wet floor, or earth. GFCI plugs do not protect against short circuits, overloads, or shocks. NOTE: The GFCI plug provided will "open" each time that it is disconnected from the AC wall receptacle. To ensure readiness for use, press the reset button each time you connect the tool to the power supply. The GFCI plug can be tested with the TEST and RESET buttons. To test:  Depress the TEST button. This should cause the RESET button to pop out.  To restore power, depress the RESET button. Perform this test monthly to ensure proper operation of the GFCI. WARNING: Do not operate tool without GFCI intact. Do not replace cord in order to bypass the GFCI. If the cord is damaged, do not use the product, take the product to an authorized service center for repair. Failure to do so can result in serious personal injury. 25' 16 16 16 16 14 14 50' 16 16 16 14 14 12 100' 16 16 14 12 10 **Used on 12 gauge - 20 amp circuit.
