EXTENSION CORDS Use oniy3-wirs extensioncords t_et have 3-prong grounding plugsand 3-pole receptaclesthat accept the tool's plug. When usinga powertoolat a considerabledistancefromthe powersource, use an extensioncordheavy enoughto carry the current that the tool will draw. An undersizedextension cord will cause a drop in line voltage, resulting in e loss of power and causing the motor to overheat. Use the chart providedbelow to determine the minimum wire size required in an extension cord. Only round jacketed cords listed by Underwriters Laboratories(UL)should be used. • "Ampere rel,ing(on tool dab= plate) 0-2.0 2.1-3.4 3.5-5.0 5.1-7.0 7.1-12.0 Cord Length 25' "_6 Wire Size (A.W.G.) 16 "_6 t6 14 50' 16 16 16 14 14 100' 1'6 1'6 1'4 1'2 10 12.1-16.0 14 12 -- -Used on 12 gauge- 20 amp circuPL NOTE: AWG = American Wire Gauge When workingwith the too] outdoors, use an extension cord that is designed for outside use. This is indicated by the letters "WA"on the cord'sjacket. Before using an extension oord, inspect it for loose or exposed wires and cut or worn insulation. WARNING: Keep the extension cord deer of the working arcs. Position the cord so that it will not get caught on lumber,tools or otherobstructionswhile you are workingwi.itna power toot. Failureto do so can resultin serious personal injury. •_ WARNING: Check extension cordsbel:oreeach use. If damaged replaceimmediately.Never usetool with a damaged cordsince touchingthe damagedarea could cause electricalshock resulting in sedous injury. ,_ WARMING: The saw's motor cord must only be pluggedintothe receptacle providedonthe saw which is controlledby the saw's master switch. Never plug the motor cord d_'ectty"intoan extension cord as this wi_ stop the saw's motor from turning OFF. ELECTRICAL CONNECTION This too[ is powered by a precisionbuilt electricrootor. It shouldbe connected to a power supply t_at is 120 volts, 60 Hz, A¢ only (normal household currentJ. Do not operate this toot on directcurrent (DC). A substantial voltage drop will cause a loss of power and the motor will overheat, fftha saw does not operatewhen plugged into an outlet, double check the power supply. SPEED AND WIRING The no-load speed of this tool is approximately 4,800 rpm. Thissbeed is not constant and decreases under a load or with lower voltage. For voltage, the wiringin a shop is as important as the motor's horsepowerratlt_. A Lineintended only for lights oannot properly carry a power tool motor. Wire that is heavy enough for a shortdis_nce wi!!be too light for a greater distance.Ailne that can support one power tool _ay not bs able to support two or three tools. GROUNDING INSTRUCTIONS In the eventof a malfunctionor breakdown,grounding providesa path of least raslstanoefor electriccurrent to reduce the risk of electric shook.]his tool is equipped with an electriccord havingan equipment-groundingconductor and a groundingplug. The plug must be plugged intoa matching outlet that is properly installedand groundedin accordancewith all localcodes and ordinances. Do not modifythe ptug provided.
