Unless a special order is placed, the saw is shipped ready to run for 200-230 volts operation. Should it be necessary to re-wire your saw for 460 volts, refer to Delta Instruction Manual for 24 volt LVC (Low Voltage Control) Magnetic Motor Control Systems and contact a qualified electrician for proper procedures to convert the saw for 460 volt operation.

GROUNDING INSTRUCTIONS

WARNING: THIS TOOL MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR FROM

ELECTRIC SHOCK.

1. All grounded, cord-connected tools:

In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool is equipped with an electric cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Do not modify the plug provided - if it will not fit the outlet, have the proper outlet installed by a qualified electrician.

Improper connection of the equipment-grounding conductor can result in risk of electric shock. The conductor with insulation having an outer surface that is green with or without yellow stripes is the equipment- grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal.

Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded.

Use only 3-wire extension cords that have 3-prong grounding type plugs and matching 3-conductor receptacles that accept the tool???s plug, as shown in Fig. C.

Repair or replace damaged or worn cord immediately.

2. Grounded, cord-connected tools intended for use on a supply circuit having a nominal rating between 150 - 250 volts, inclusive:

This tool is intended for use on a circuit that has an outlet that looks like the one illustrated in Fig. C. The tool has a grounding plug that looks like the plug illustrated in Fig. C. Make sure the tool is connected to an outlet having the same configuration as the plug. No adapter is available or should be used with this tool. If the tool must be reconnected for use on a different type of electric circuit, the reconnection should be made by qualified service personnel; and after reconnection, the tool should comply with all local codes and ordinances.

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. 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.

4.If the blade is not square with the table an adjustment is necessary. Loosen two bolts (C) Fig. 43.

5. Loosen screw (D) Fig. 44, located inside of yoke (E).

6. Hold cuttinghead with left hand as shown in Fig. 45, loosen bevel clamp handle (F) and tilt the motor until the saw blade is flush against the square.

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.

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).

10.Replace blade guard that was removed in STEP 2.

ADJUSTING TRACK ARM

CLAMP HANDLE

The track arm clamp handle (A) should lock the track arm

(B) when the handle is in the position shown in Fig. 48, and the track arm should be loose when the handle is pushed back resting on stop (C). If an adjustment to the track arm handle (A) is necessary, proceed as follows:

1.DISCONNECT TOOL FROM POWER SOURCE.

2.Unscrew and remove stop (C) Fig. 48, and unscrew and remove track arm clamp handle assembly (A).

3.Remove clamp (D) Fig. 49, from opposite side of track arm and change position of bolt head (E).

4.Replace track arm clamping handle assembly (A) Fig. 48, and check for proper locking position. Make further adjustment if necessary until clamping handle locks properly.

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. If saw blade travel is not 90 degrees to the fence, this means that the track arm is not properly aligned.

To check and adjust, proceed as follows:

1.DISCONNECT TOOL FROM POWER SOURCE.

2.Remove blade guard assembly and saw blade from the cuttinghead assembly (A) Fig. 50, and insert wrench

(B) between arbor flanges in place of blade as shown. Tighten arbor nut.

3.Place a steel square (C) Fig. 50, against fence as shown, and lower cuttinghead assembly (A) so that wrench (B) just clears the table top.

4.Pull cuttinghead assembly (A) Fig. 50, along square

(C). If wrench (B) does not travel parallel to the square (C), the following adjustment is necessary.

5.Remove three screws (D) Fig. 51, and remove miter scale (E).

6.Loosen three screws (F) Fig. 52, and loosen track arm clamp handle (G).

7.To move front end of track arm to the right, loosen set screw (H) Fig. 53, and tighten set screw (J). To move front end of track arm to the left, loosen set screw (J) and tighten set screw (H).

8.When the cuttinghead travels parallel to the square, tighten three screws (F) Fig. 52. Replace miter scale (E) Fig. 51, and replace and tighten three screws (D). Make certain the zero graduation mark on the scale (E) lines up with the pointer (K).

9.Replace blade and blade guard assembly.

REMOVING ???HEELING???

IN SAW CUT

Even though the cuttinghead travel may be perfectly aligned at 90 degrees to the fence, the blade itself may not be 90 degrees 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 TOOL FROM POWER SOURCE.

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.Using three 2 x 4???s four inches in height, as shown at

(B) Fig. 55, lay a square on the 2 x 4???s with one end of the square against the plywood (A) and the other end against the saw blade, as shown in Fig. 55.

4. If the blade is not parallel to the square, an adjustment is necessary. 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 clamped to the track arm with a small ???C??? clamp will prevent unnecessary travel of the cuttinghead on the track arm. 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.

ADJUSTING BLADE GUARD

AND ANTI-KICKBACK ROD

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.

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

C

Fig. 62

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.

22

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.
