Tighten locknuts (D). Fig. 36 4.
ADJUSTING CUTTINGHEAD BALL BEARINGS AGAINST TRACK RODS The carriage is mounted on four pre-loaded, prelubricated, shielded ball bearings: two on fixed shafts (on saw blade side of track arm); the other two on adjustable eccentric shafts. C The ball bearings must ride smoothly and evenly against the track rods to do accurate work. If wear should ever develop in the track rods causing “play” between the ball bearings and the track rods, the ball bearings can be adjusted as follows: A 1.
ADJUSTING BLADE SQUARE WITH TABLE TOP A The saw blade must be square with the table top in order to produce accurate work. To check if the blade is square with the table: B 1. DISCONNECT MACHINE FROM POWER SOURCE. 2. Remove the blade guard and place the cuttinghead in a cross-cut position as shown in Fig. 42. 3. Place a steel square (A) Fig. 42, against saw blade (B) and table, and check to see if the blade (B) is square with the table. Make certain the square is between the teeth of the saw blade.
7. When the adjustment is made, turn the bevel clamp handle (F) Fig. 46, counterclockwise to lock the motor in position. NOTE: If the bevel clamp handle (F) does not completely lock the motor, the clamp handle can be repositioned by pulling out the handle and repositioning it on the serrated nut located under the handle. 8. Tighten bolt (D) Fig. 44, and two bolts (C) Fig. 43. 9. Loosen screw (G) Fig. 47. Move pointer (H) to zero mark on the bevel scale (J). Tighten screw (G). F 10.
ADJUSTING SAW TRAVEL SQUARE WITH FENCE A The 12” Radial Arm Saw is equipped with 90° and 45° positive miter stops. This feature makes it possible to produce accurate miter cuts and square cross-cuts at all times. To do accurate work, the saw blade travel must be 90° to the fence. If saw blade travel is not 90° to the fence, this means that the track arm is not properly aligned. B To check and adjust, proceed as follows: C 1. DISCONNECT MACHINE FROM POWER SOURCE. Fig. 50 2.
REMOVING “HEELING” IN SAW CUT Even though the cuttinghead travel may be perfectly aligned at 90° to the fence, the blade itself may not be 90° 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 MACHINE 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.
ADJUSTING BLADE GUARD AND ANTI-KICKBACK ROD E On all ripping and plowing operations, the infeed side 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 wing nut (C), moving the kickback rod to the desired position and tightening wing nut (C).
4. 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). C C Fig. 61 MACHINE USE B 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.
COMPOUND MITER CUTTING B 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. A RIPPING Ripping involves making a lengthwise cut through a board along the grain. When ripping, the track arm (B) Fig.
CONSTRUCTING A PUSH STICK 27 Fig. 67 1/2" SQUARES CUT OFF HERE TO PUSH 1/2" WOOD CUT OFF HERE TO PUSH 1/4" WOOD NOTCH TO HELP PREVENT HAND FROM SLIPPING MAKE FROM 1/2" OR 3/4" WOOD OR THICKNESS LESS THAN WIDTH OF MAT’L. TO BE CUT PUSH STICK When ripping work less than 4 inches wide, a push stick should be used to complete the feed and could easily be made from scrap material by following the pattern shown in Fig. 67.
