ELECTRICAL DOUBLE INSULATION 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. 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, 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. 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 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: 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 2. 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: To ensure readiness for use, press the reset button each time you connect the pressure washer to the power supply. The GFCI plug can be tested with the TEST and RESET buttons. To test:  Press the TEST button. You will hear a "click" sound and the red LED light will go out.  To restore power, press the RESET button. The LED light will illuminate to indicate power has been restored. Perform this test monthly to ensure proper operation of the GFCI.  To reduce the risk of electric shock the supervisory circuit must be operated before an appliance is plugged into any receptacle on the device. 8 - English
