EXTENSION CORDSUse only 3-wire extension cords that have 3-pronggrounding plugs and 3-pole receptacles that acceptthe tool's plug, When using a power tool at a consid-erable distance from the power source, use anextension cord heavy enough to carry the current thatthe tool will draw, An undersized extension cord willcause a drop in line voltage, resulting in a loss ofpower and causing the motor to overheat, Use thechart provided below to determine the minimum wiresize required in an extension cord. Only round jack-eted cords listed by Underwriter's Laboratories (UL)should be used,Length of Extension Cord Wire Size (A.W.G.)Up to 25 feet 1426-100 feet 12When working with the tool outdoors, use an exten-sion cord that is designed for outside use. This isindicated by the letters WA on the cord's jacket,Before using an extension cord, inspect it for loose orexposed wires and cut or worn insulation.,_, CAUTION: Keep the cord away from the cuttingarea and position the cord so that it will not becaught on lumber, tools, or other objects duringcutting operations.ELECTRICAL CONNECTIONYour Sears Craftsman Radial Arm Saw is powered bya precision built electric motor, It should be connectedto a power supply that is 120 volts, 60 Hz, AC only(normal household current). It should be connectedto a 240 volt power supply only if it has been resetaccording to the instructions in this manual. Themotor has been set at the factory for 120 volts; if it isreconnected to operate at 240 volts, the main powercord plug and any receptacle must be replaced withdevices rated for 240 volts, This tool will not operateon direct current (DC), A substantial voltage drop willcause a loss of power and the motor will overheat. Ifthe saw does not operate when plugged into an outlet,double check the power supply.SPEED AND WIRINGThe no-load speed of your saw is approximately 3,450rpm. This speed is not constant, For voltage, thewiring in a shop is as important as the motor's horse-power rating, A line intended only for lights cannotproperly carry a power tool motor, Wire that is heavyenough for a short distance will be too light for agreater distance. A line that can support one powertool may not be able to support two or three tools.GROUNDING INSTRUCTIONSIn the event of a malfunction or breakdown, groundingprovides a path of least resistance for electric currentto reduce the risk of electric shock, This tool isequipped with an electric cord having an equipment-grounding conductor and a grounding plug, The plugmust be plugged into a matching outlet that is properlyinstalled and grounded in accordance with all localcodes and ordinances,Do not modify the plug provided, If it will not fit theoutlet, have the proper outlet installed by a qualifiedelectrician. Improper connection of the equipment-grounding conductor can result in a risk of electricshock, The conductor with insulation having an outersurface that is green with or without yellow stripes isthe equipment-grounding conductor, If repair orreplacement of the electric cord or plug is necessary,do not connect the equipment-grounding conductor toa live terminal,Check with a qualified electrician or service personnelif the grounding instructions are not completelyunderstood, or if in doubt as to whether the tool isproperly grounded,Repair or replace a damaged or worn cord immedi-ately,This tool is intended for use on a circuit that has anoutlet like the one shown in Figure 1, It also has agrounding pin like the one shown,GROUNDINGPINCOVEROF GROUNDEDOUTLETBOX Fig. 1[RAFTSMAN_RADIALSAW 315.220100 8
