  • 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 bolt 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 volts, 60 Hz, AC only (normal household current).
  • 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 23: Removing The Blade

    4 hex nuts (5/16-18) 4 flat washers (5/16 in.) • Attach the supports to the side of the saw base. There are holes in both sides of each support. The long side of each support (with the slotted holes) fits against the saw base.

  • Page 24: Setting The Arm Lock Knob

    YOKE CLAMP See Figures 16A and 16B. The yoke clamp keeps the yoke from rotating on the carriage when you want the saw blade to be station- ary. Use this procedure to check and set the yoke clamp. • Release the yoke lock handle (below the arm on the right side) so the motor can be rotated.
  • Page 25 SETTING BEVEL LOCK See Figures 17A -17C. The bevel lock lever locks the blade at desired angles other than the preset positive stop angles. The bevel lock lever is preset at the factory but may need readjustment after shipping or extended use. Check for overtightness or looseness and make any neces- sary adjustments as follows:...
  • Page 26 Replace the rear cover and rear cover screws. • Tighten screws securely. HEXBOLT(2) HEXNUT(2) CR_FT_MRN °RADIAL SAW 315.273731 COLUMN ADJUSTING See Figures 19A - 19D. The purpose of this procedure is to check whether the inner column tube is snug in the housing and to remove any looseness.
  • Page 27 • Rotation check: To check the rotation, hold the front of the arm with one hand and grasp the top of the column support with the other. Press the arm to the side. If there is play between the column support and the column tube, it needs to be adjusted.
  • Page 28 Loose carriage bearings permit the blade to wander slightly while cutting, which will result in a poor cut and more wear and tear on the saw. Use the following steps to check for tightness and to then adjust the bearings if needed.
  • Page 29 Move the arm to the opposite side and repeat the above procedure. When the opposite side is level, recheck the first side to make sure that it is still accurate and even. • Return the saw and motor to normal height and position. rRRFTSMRN ° RADIAL SAW315.273731 RIGHTSIDE TABLESUPPORT...
  • Page 30 • Snap the U-clip onto the front edge of the saw base. Line up the hole in the U-clip with the saw base hole just to the left of the center notch in saw base. See Figure 22B. • Place the table, top up, on the table supports so the center counterbored hole lines up over the hole in the U-clip.
  • Page 31 LEVELING FRONT TABLE See Figure 23. If there are any high or low areas on the front table, they should be removed by adjusting the leveling screws in the center holes on the front table. • Place the rear table on its edge across the front table to check for gaps.
  • Page 32 See Figures 25A and 25B. • Collect the blade and hardware that were removed earlier. Place the inner blade washer, saw blade, outer blade washer, and blade nut on the blade arbor. See Figure 25A. Note: The flat concave side of blade washers go against the blade.
  • Page 33 ALIGN RIVING KNIFE TO BLADE See Figures 26A - 26C. When ripping the riving knife must be centered with the blade to ride in the middle of the kerf and keep it from binding. Binding pinches the blade. Blade pinching can cause kickback. There are two pairs of anti-kickback ,_!1 WARNING: Failure to use the riving knife, hold...
  • Page 34 The control cut device offers many benefits. As it increases operator control, it eliminates the risk in a cross cut of the saw "climbing" out and over the workpiece at the operator. Feed control of the blade as it cuts through the workpiece increases, as does the accuracy of the cut.
  • Page 35 (0 °) and leave it unlocked. • Lower the arm with the elevating handwheel until the saw blade just clears the front table. Lock the yoke lock handle (right side of saw, below yoke) and the bevel lock lever.
  • Page 36 Place the square flat against the blade between two teeth. • If both the top and bottom of the saw blade are flat against the square, no adjustment is needed. • If the saw blade gaps at the top or bottom, remove the bevel index cap by removing the two phillips head screws (below the handle).
  • Page 37 The blade must be angled at 90 ° to the fence when the handle is at the front of the saw. If not, kickback could result during a cross cut. Kickback can cause serious injury by throw- ing the workpiece toward the operator, tn addi-...
  • Page 38 PARALLELING BLADE TO TABLE See Figures 31A-31C. This procedure squares the blade to the table at 90 ° bevel so horizontal cuts will be accurate. This also reduces kickback, as well as splintering and burning of the cut edges of the workpiece. If the blade is not at 90 °...
  • Page 39 ALIGNING RIP SCALE See Figures 32A - 32B. 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 positioned directly behind the front table. The lower scale is used when the fence is at the extreme rear, directly in front of the column.
  • Page 40 The control cut device offers many benefits. As it increases operator control, it eliminates the risk in a cross cut of the saw "climbing" out and over the workpiece at the operator. Feed control of the blade as it cuts through the workpiece increases, as does the accuracy of the cut.
  • Page 41 It can make dado or molding cuts with special attachments. This saw is designed to cut wood and wood composi- tion products only. The three-prong plug must be plugged into a match- ing outlet that is properly installed and grounded according to all local codes and ordinances.
  • Page 42 The yellow switch key prevents accidental starting of the main power switch when saw is not being used. To activate the switch, insert the switch key and lift switch to ON position. To lock the switch once it has been pressed to OFF, remove the yellow key.
  • Page 43 Use a pushblock when the blade is between 1/2 in. and 2 in. from the fence. (If the cut is narrower than 1/2 in., use a different saw.) Refer to the drawings and instructions provided so you can make safer and more precise cuts.
  • Page 44 • Release the switch trigger and let the carriage return to the back. Turn the saw off with the switch on the arm but hold the handle until the blade stops rotating. Adjust the height with the elevating handwheel so the blade will rotate freely in the kerf.
