  • Page 7 5/16-18x5/8" carriage head screws (A) Fig. 4A and Fig. 4B, 5/16" flat washers (B), 5/16" lockwashers (C) and 5/16" hex nuts (D). Return saw to upright position. ASSEMBLING OVERARM ELEVATING HANDLE 1.
  • Page 8 ASSEMBLING CUTTINGHEAD TO TRACK ARM 1. Raise the track arm assembly (A) Fig. 7, by turning overarm elevating handle (F) Fig. 2. 2. Remove packing material from around cuttinghead assembly (B) Fig. 7. 3. Push track arm clamp lever (C) Fig. 7, to the rear until it rests against stop (D) as shown.
  • Page 9 1. Assemble bracket (A) to the bottom of the right side of saw base, as shown in Fig. 13. Place a 1/4" flat washer onto a 1/4-20x3/4" hex head screw and insert screw through hole in the bottom of the right side of the saw base.
  • Page 10 ADJUSTING TABLE BRACKETS PARALLEL TO TRACK ARM To perform accurate work, the track arm must be parallel to the table top brackets at both the front and rear of the machine. To check if the alignment is correct, proceed as follows: 1.
  • Page 11 and outer flange (H) and tighten arbor nut (E). Make certain wrench (F) is above the table surface. If necessary raise track arm. 4. Loosen cuttinghead clamp knob (J) Fig. 20 and move cuttinghead (C) to the front of track arm (K). Loosen track arm locking lever (L), pull out on track arm index knob (M) and rotate track arm (K) until wrench (F) is over left table bracket (N).
  • Page 12 (A) so threaded hole (C) is on the inside of table mounting bracket. 3. Insert threaded end of table clamp rod (D) Fig. 26, through metal support (E) at the front of the saw and thread rod through the tapped hole in table clamp (A) as shown.
  • Page 13 BETWEEN THE TWO BLADE FLANGES (B) AND (C) WITH THE RECESSED SIDES OF THE FLANGES AGAINST THE SAW BLADE. 3. Assemble the saw blade (D) Fig. 30, between the two blade flanges making sure the teeth of the saw blade are pointing down at the front.
  • Page 14 7. Fig. 32, illustrates the blade guard assembly attached to the motor assembly. NOTE: The lower retractable blade guard provides opera- tor protection in an axial direction to the saw blade. Care must be taken to eliminate potential hazards of the lower blade guard.

  • Page 15: Operating Controls And Adjustments

    OPERATING CONTROLS AND ADJUSTMENTS Every Delta Radial Saw is thoroughly tested, inspected and accurately aligned before leaving the factory, and when delivered is ready for operation after it is assembled. However, regardless of the care with which this or any piece of fine machinery is manufactured, inspected and shipped, it is possible that rough handling in shipment may make minor adjustments necessary.

  • Page 17 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: 1. DISCONNECT TOOL FROM POWER SOURCE. 2. Remove the blade guard and place the cuttinghead in a cross-cut position as shown in Fig.
  • Page 18 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 19 ADJUSTING SAW TRAVEL SQUARE WITH FENCE The 12” Radial Arm Saw is equipped with 90 degree and 45 degree 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 degrees to the fence.
  • Page 20 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. CROSS-CUT STOP Fig.
  • Page 21 (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.

  • Page 24 The cuttinghead is positioned on the in-rip scale to the desired setting and clamped in position. The workpiece is fed from the right side of the saw. Fig. 66, shows a typical in-ripping operation on the radial saw. Note the push stick is being used due to the narrow workpiece.

  • Page 25: 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.
