Page 18 DISCONNECT MACHINE FROM POWER SOURCE. 2. Remove blade guard assembly (C) Fig. 37, and saw blade. 3. Remove rear end plate from track arm and remove cuttinghead assembly (D) Fig. 37, from track arm.
Page 19 BEARINGS AGAINST TRACK RODS The carriage is mounted on four pre-loaded, pre- lubricated, shielded ball bearings: two on fixed shafts (on saw blade side of track arm); the other two on adjustable eccentric shafts. The ball bearings must ride smoothly and evenly against the track rods to do accurate work.
Page 20 ADJUSTING BLADE SQUARE WITH TABLE TOP 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: DISCONNECT MACHINE FROM POWER SOURCE. 2. Remove the blade guard and place the cuttinghead in a cross-cut position as shown in Fig.
Page 21 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 re- positioned by pulling out the handle and repositioning it on the serrated nut located under the handle.
Page 22 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. To check and adjust, proceed as follows: DISCONNECT MACHINE FROM POWER SOURCE.
Page 23 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. CROSS-CUT STOP A block of wood placed at (B) Fig.

“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.
Page 26 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. IN-RIPPING In-ripping involves all of the general conditions stated under RIPPING.
Page 27: Constructing A Push Stick
CONSTRUCTING A 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.
