EXTENSION CORDS

Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept

the tool'splug. When using a power tool at a consider- able distance from the power source, use an exten- sion cord heavy enough to carry the current that the tool will draw. An undersized extension cord will cause a drop in line voltage, resulting in a loss of power and causing the motor to overheat. Use the chart provided below to determine the minimum wire size 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	14
26-100 feet	12

When working with the tool outdoors, use an exten- sion cord that is designed for outside use. This is indicated by the letters WA on the cord'sjacket. Before using an extension cord, inspect it for loose or exposed wires and cut or worn insulation.

_k CAUTION: Keep the cord away from the cutting area and position the cord so that it will not be

caught on lumber, tools, or other objects during cutting operations.

ELECTRICAL CONNECTION

Your Sears Craftsman Radial Arm Saw is powered by

aprecision built electric motor. It should be connected to a power supply that is 120 volta, 60 Hz, AC only (normal household current). It should be connected to a 240 volt power supply only if it has been reset according to the Instructions in this manual. The motor has been set at the factory for 120 volts; if it is reconnected to operate at 240 volts, the main power cord plug and any receptacle must be replaced with devices rated for 240 volts. This tool will not operate on direct current (DC). A substantial voltage drop will cause a loss of power and the motor will overheat. If the saw does not operate when plugged into an outlet, double check the power supply.

SPEED AND WIRING

The no-loadspeed of your saw is approximately 3,600 rpm. This speed is not constant. For voltage, the wiring in a shop is as importantas the motor'shorse- power rating. A line intended only for lights cannot properly carry a power tool motor. Wire that is heavy enough for a short distance will be too light for a greater distance. A line that can support one power tool may not be able to supporttwo or three tools.

GROUNDINGINSTRUCTIONS

In the event of a malfunction or breakdown, grounding providesa path of least resistance for electriccurrent to reduce the risk of electric shock. This tool is equipped with an electric cord having an equipment- groundingconductor and a grounding plug. The plug must be plugged into a matching outlet that is prepedy installedand grounded in accordance with all local codes and ordinances.

Do not modify the plug provided. If it will not fit the outlet, have the proper outlet installed by a qualified electrician. Improper connection of the equipment- groundingconductor can result in a risk of electric shock. The conductor with insulationhaving an outer surface that is green with or without yellow stripes is the equipment-groundingconductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-groundingconductorto a live terminal.

Check with a qualified electrician or service personnel

if the grounding instructionsare not completely understood, or if in doubt as to whether the tool is

propedy grounded.

Repair or replace a damaged or worn cord immedi- ately.

This tool is intended for use on a circuit that has an outlet like the one shown in Figure 1. It also has a grounding pin like the one shown.
