6. Loosen three screws (F) Fig. 52, and loosen track arm clamp handle (G). 7. To move front end of track arm to the right, loosen set screw (H) Fig. 53, and tighten set screw (J). To move front end of track arm to the left, loosen set screw (J) and tighten set screw (H). 8. When the cuttinghead travels parallel to the square, tighten three screws (F) Fig. 52. Replace miter scale (E) Fig. 51, and replace and tighten three screws (D). Make certain the zero graduation mark on the scale (E) lines up with the pointer (K). 9. Replace blade and blade guard assembly. 19 C B A Fig. 50 D E K Fig. 51 F F G Fig. 52 H J Fig. 53 REMOVING “HEELING” IN SAW CUT Even though the cuttinghead travel may be perfectly aligned at 90 degrees to the fence, the blade itself may not be 90 degrees or square with the fence, as shown in Fig. 54. This condition is known as “heeling.” To check and adjust, proceed as follows: 1. DISCONNECT TOOL FROM POWER SOURCE. Fig. 54 2. Take a piece of 3/4” plywood or similar piece of wood (A) Fig. 55, at least 5” wide, and clamp it between the table boards in place of the fence, as shown. 3. Using three 2 x 4’s four inches in height, as shown at (B) Fig. 55, lay a square on the 2 x 4’s with one end of the square against the plywood (A) and the other end against the saw blade, as shown in Fig. 55. 4. If the blade is not parallel to the square, an adjustment is necessary. Loosen yoke clamping handle and the two screws (C) Fig. 56. Swivel the yoke (D) until the saw blade is parallel with the square. Then tighten yoke clamping handle and two screws (C) Fig. 56. A B B Fig. 55 D C Fig. 56 CROSS-CUT STOP A block of wood clamped to the track arm with a small “C” clamp will prevent unnecessary travel of the cuttinghead on the track arm. This is especially useful when performing repetitive cutting operations. Clamp the block of wood to the right side of the track arm at a position which will stop the cuttinghead travel as soon as the saw blade cuts through the workpiece. 20 ADJUSTING BLADE GUARD AND ANTI-KICKBACK ROD On all ripping and plowing operations, the back part of the blade guard is lowered so that it just clears the material. This will prevent the material from being lifted off the table. Also, lower the kickback rod (A) Fig. 57, so that the kickback fingers (B) are below surface of material. Rod (A) can be raised or lowered by loosening wingnut (C), moving the kickback rod to the desired position and tightening wingnut (C). The kickback fingers (B) will then come into contact with the material, preventing “kickback.” The splitter (D) Fig. 57, should be in line with the saw blade. If an adjustment is necessary, DISCONNECT TOOL FROM POWER SOURCE. Rod (A) can be adjusted sideways by tightening or loosening two screws (E) Fig. 57. A E C D B Fig. 57 ADJUSTING TRACK ARM STOP When making cuts with the track arm in the straight cutoff position and the motor tilted for a 45 degree bevel cut, it is necessary to rotate stop (A) Fig. 58, to the downward position as shown in Fig. 59. This will prevent the saw blade from coming into contact with the column. A Fig. 58 A Fig. 59 21 ASSEMBLING ACCESSORY 33-967 MOULDING CUTTERHEAD GUARD To assemble the accessory 33-967 Moulding Cutterhead Guard to your Radial Arm Saw, proceed as follows: 1. DISCONNECT TOOL FROM POWER SOURCE. 2. Remove blade, and blade guard assembly. 3. Move motor so that the arbor is in the down position, as shown in Fig. 60. 4. Place guard (A) Fig. 60, on motor with stud on motor inserted through hole in guard. Thread special nut (B) on motor stud and fasten with screwdriver, as shown in Fig. 60. 5. When using the moulding cutterhead, the motor should be positioned as shown in Fig. 61. The height of the guard (A) Fig. 61, can be adjusted by loosening three screws (C). B A Fig. 60 C C Fig. 61 OPERATIONS CROSS-CUTTING The first operation which should be learned on the radial saw is cross-cutting. Cross-cutting consists of supporting the workpiece against the fence and pulling the saw blade through the material at right angles to it. When cross-cutting, the track arm (A) should be indexed at “0” and the track arm clamp handle (B) Fig. 62, tightened. The fence should be clamped between the table boards. The saw blade is to be to the left and behind the fence. The workpiece is placed on the table and butted against the fence. The saw blade should be clear of the fence and table when the machine is turned on. Then the saw blade is lowered until it lightly cuts into the table surface. The operator should position himself a little to the left of the machine for better visibility while cutting. Pull the saw blade across the work, just far enough to cut it off, and return the saw blade to its starting position. Wait for the blade to stop before touching the cut off piece. CAUTION: The operator must always be conscious of where his hands are; that they are clear of the blade and holding the workpiece firmly. As an added measure of operator safety, since the spli...
