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.

ADJUSTING

TRACK ARM STOP

When making cuts with the track arm in the straight cut- off 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.

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).

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.

MITER CUTTING

Miter cutting is similar to cross-cutting except the workpiece is cut off at an angle (up to 45 degrees right or left) rather than being cut off square. The settings and operation are performed in the same manner as cross- cutting except that the track arm (A) Fig. 63, is first positioned to the desired angle on the miter scale before it is clamped in place with clamp handle (B). The operator should position the hand holding the workpiece on the opposite side to the direction of the miter so the blade is pulled through the workpiece and away from the hand. Fig. 63, shows a typical miter cutting operation on the radial saw.

COMPOUND MITER

CUTTING

Compound miter cutting is performed in the same manner as miter cutting except the saw blade is also tilted to cut a bevel. The settings and operation are similar to miter cutting except that the blade is first tilted to the desired angle on the bevel scale before it is clamped in place. Fig. 64, shows a compound miter cutting operation on the radial saw.

RIPPING

Ripping involves making a lengthwise cut through a board along the grain. When ripping, the track arm (B) Fig. 65 and 66, are clamped at ???0??? on the miter scale. The yoke is then positioned and clamped so that the blade is parallel to the fence in either the inboard or outboard position.When feeding the material, one edge rides against the fence while the flat side of the board rests on the table. The guard should be lowered on the infeed side until it almost touches the workpiece, as shown in Figs. 65 and 66, to act as a holddown. The splitter and anti-kickback fingers (A) Fig. 65, should be adjusted accordingly. The operator???s hands should always be well away from and to the side of the blade. When ripping narrow work, always use a push stick as shown in Fig. 66, to push the work between the fence and blade. NOTE: The workpiece must have one straight edge to follow the fence. If board is bowed, place hollow side down. IMPORTANT: The cuttinghead clamp knob

(C) Figs. 65 and 66, should be securely tightened for all ripping operations. Pay particular attention to warning label which states that material must never be fed into the outfeed end of the blade guard.

OUT-RIPPING

Out-ripping involves all of the general conditions stated under RIPPING. The yoke is clamped at right angle to the track arm with the blade guard facing the front of the machine. The cuttinghead is positioned on the out-rip scale to the desired setting and clamped in position. The workpiece is fed from the left side of the saw. Fig. 65, shows a typical out-ripping operation on the radial saw.
