  • Page 4 M KEEP WORK AREA CLEAN. Cluttered work areas and work benches invite accidents. DO NOT leave tools or pieces of wood on the saw while it is in operation. Keep floors clean and free of saw- dust.

  • Page 5: Electrical

    REMOUNTING THE MOTOR; unplug the saw and remove the switch key. WARNING: When servicing, use only identical Craftsman replacement pads. Use of any other parts may create a hazard or damage product. • NEVER USE THIS TOOL IN AN EXPLOSIVE ATMOSPHERE.
  • Page 6 • USE A SUPPORT FOR THE SIDES AND BACK OF THE SAW TABLE when sawing wide or long workpieces to minimize the risk of blade pinching and kickback. Use a sturdy "outrigger"support to prevent tipping if a table extension more than 24 inches long is attached to the saw.
  • Page 7 • SECURE THE SAW. Firmly belt the saw to the leg stand to keep the saw from tipping,walking, or sliding. • DO NOT SET UP WORK WITH THE BLADE SPINNING. Keep the saw power off until you are ready to use it.
  • Page 8 ELECTRICAL CONNECTION Your Sears Craftsman Radial Arm Saw is powered by a precision 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.
  • Page 9 CHANGING VOLTAGE See Figures 2-4. Your radial saw has been set up at the factory to operate efficiently on a 120V AC single voltage circuit. However, if heavy duty operation is required, the circuits are overloaded, or the circuit is low voltage, have a qualified electrician change the voltage on the main power system to a 240V AC voltage circuit.
  • Page 10 A type of rip cut in which the motor is between the blade and the column• (The blade is "outside" the motor). Puahatick A device used to feed the workpiece through the saw blade duringcutting operations. It helps keep the operator's hands well away from the blade. Rabbet A type of cut that gives a notch in the edge of a workpiece.
  • Page 11 Resin A sticky, sap-based substance. Rip Cut In a radial saw, a cut made with the blade parallel to the fence and perpendicular to the arm. Can be across or with the grain. The teeth point up at the point of contact with the wood.

  • Page 41 ALIGNING RIP SCALE INDICATORS See Figures 33A - 33B. The rip scale indicators on the arm show the distance between the blade and the rip fence. The upper scale is used when the fence is positioneddirectly behind the front table. The lower scale is used when the fence is at the extreme rear, directly in front of the column.
