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.

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).

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 splitter and anti-kickback fingers are not used in the cross-cutting operation, the anti-kickback rod (C) can be turned upside down and locked in place so the rod just clears the workpiece. In this position the rod can act as

a guard from the exposed teeth of the blade. Fig. 62 shows a cross-cutting operation on a radial saw. The op- erator should always be sure to return the cutterhead carriage to the full rear position after each cross-cut operation.

NOTE: When cross-cutting material more than 1” thick, the fence must be positioned immediately behind the fixed front table board.
