GENERAL SAFETY RULES
Woodworking can be dangerous if safe and proper operating procedures are not followed. As with all machinery, there are certain hazards involved with the operation of the product. Using the machine with respect and caution will considerably lessen the possibility of personal injury. However, if normal safety precautions are overlooked or ignored, personal injury to the operator may result. Safety equipment such as guards, push sticks, hold-downs, featherboards, goggles, dust masks and hearing protection can reduce your potential for injury. But even the best guard won’t make up for poor judgment, carelessness or inattention. Always use common sense and exercise caution in the workshop. If a procedure feels dangerous, don’t try it. Figure out an alternative procedure that feels safer. REMEMBER: Your personal safety is your responsibility.
This machine was designed for certain applications only. Delta Machinery strongly recommends that this machine not be modified and/or used for any application other than that for which it was designed. If you have any questions relative to a particular application, DO NOT use the machine until you have first contacted Delta to determine if it can or should be performed on the product.

These stops are accurately adjusted at the factory; however, adjustments can be made if necessary.
Once the "Micro-Set" stops are set, you can be assured of quick, positive settings at the three positions.
Before determining if the "Micro-Set" stops require adjustment, check saw travel for squareness with table fence. To do accurate work, saw travel must be 90 degrees to the fence. Check and adjust as follows:
1. DISCONNECT MACHINE FROM POWER SOURCE.
2. Place a square (A) Fig. 40, against fence (B), as shown, and lower cuttinghead (C) so that saw blade just clears table top.
3. Pull cuttinghead (C) Fig. 40, along square (A). If saw blade does not travel parallel to the square, the following adjustment is necessary.
4. Remove cover plate (D) Fig. 41.
5. Locate center cap screw (E) Fig. 41, inside pivot column and loosen slightly. Tap center cap screw (E) sharply with a block of wood or insert a thin wooden wedge inside the column to loosen the tapered plug (F) Fig. 41, that is attached to the cap screw (E). It is very important that the tapered plug (F) is loosened before any further adjustment is made.
6. Loosen clamp handle (G) Fig. 40.
7. Using wrench on hex nut (H) Fig. 40, turn slightly to one side. CAUTION: Do not attempt to rotate completely. Notice that the entire track also moves.
8. When saw blade tracks evenly against steel square, tighten clamp handle (G) Fig. 40, and center cap screw (E) Fig. 41.
9. Check pointer and adjust to 0 degrees, if necessary.
10. Replace cover plate (D) Fig. 41.
11. Right and left miter positions can be independently adjusted using the same procedure as above. If square is not available, trial cuts can be made to determine if adjustment is necessary.

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. 42. This condition is known as "heeling."
To check and adjust, proceed as follows:
1. Cross-cut a board and see on which side of the cut board saw teeth marks appear.
2. DISCONNECT MACHINE FROM POWER SOURCE.
3. If saw teeth marks appear on the right side, the back end of the saw blade must be shifted toward left side.
4. Loosen yoke clamp handle (A) Fig. 43. Then loosen
both screws (B) Fig. 44, and turn yoke (C) COUNTER- CLOCKWISE. If saw teeth marks appear on left side of board, turn yoke (C) CLOCKWISE.
5. Tighten yoke clamp handle (A) Fig. 43, to hold
position and retighten screws (B) Fig. 44.
6. Make another test cut and repeat steps 1 through 5
until “heeling” is eliminated.
ADJUSTABLE CROSS-CUT STOP
An adjustable cross-cut stop (A) Fig. 45, is provided to prevent unnecessary travel of the cuttinghead on the track-arm. It is especially useful when performing repetitive operations. Clamp the stop to the side of the track-arm at a position which will stop the cuttinghead travel as soon as the blade cuts through the workpiece.

ADJUSTING BLADE GUARD
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. 46, so that the kickback fingers are 1/8" below surface of material. The kickback fingers will then come into contact with the material preventing "kickback." Adjust dust elbow (B) Fig. 46, to direct sawdust to rear of machine.
CHECKING AND ADJUSTING AUTOMATIC BRAKE
After a period of extended use, the automatic brake should be checked and adjusted if necessary to maintain proper blade braking action.
NOTE: The blade stopping time should be a maximum of one second per one inch of the blade diameter.
To check the setting on the automatic brake:
1. DISCONNECT MACHINE FROM POWER SOURCE.
2. Remove four screws, three of which are shown at (A) Fig. 47, and remove fan cover (B) from the motor.
3. The air gap (D) Fig. 48, must be maintained between .008" and .012". Use a feeler gauge (C) to measure the gap.
4. If an adjustment is necessary, turn lock nut (F) Fig. 48, until a proper gap setting of .010" is attained.
5. Replace fan cover that was removed in Step 2.

LOCKING SWITCH IN THE “OFF” POSITION
IMPORTANT: When the tool is not in use, the switch
should be locked in the “OFF” position using a padlock (A) Fig. 48A, with a 3/16" diameter shackle to prevent unauthorized use.

ADJUSTING TENSION ON CUTTINGHEAD RETURN ASSEMBLY
The cuttinghead return assembly is properly tensioned when there is just enough cable tension to return the cuttinghead (A) Fig. 49, without excessive force, to the rear of the track arm (B) after completion of the cut. If an adjustment is necessary:
1. DISCONNECT MACHINE FROM POWER SOURCE.
2. To INCREASE cable tension, turn adjustment dial
(C), Fig. 49, clockwise.
3. To DECREASE cable tension, pull back on cable
tension release knob (D) Fig. 50, until the desired tension is achieved.

CROSS-CUT STOP
A block of wood placed at (B) Fig. 53 clamped to the track arm with a small “C” clamp will prevent unnecessary travel (T) of the cutting-head on the track arm. This is especially useful when performing repetitive 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.
AUXILIARY TABLE BOARD FACING
To prevent repeated cutting into the table surface which will eventually cause the table to sag, an auxiliary table board facing can be cut and fitted to the table. It can be made from 1/4plywood or particle board and should be cut to a size that will exactly cover all of the table boards in front of the fence. The auxiliary table board facing should be placed flat on the table and butted against the table fence. Fasten it to the table with a small brad or finish nail in each corner.
The life of the table boards will be greatly extended by the use of an auxiliary facing.The auxiliary facing can be replaced as often as is necessary to protect the table.
USING A TABLE EXTENSION
When a table extension more than 24 inches long is attached to the saw, a sturdy outrigger support should be provided or the stand or bench must be secured to the floor.
OPERATIONS
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 should be indexed at “0” and the track arm clamp handle 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 through the work, just far enough to cut it off, and return the saw blade to its starting position. Turn tool off. and wait for the blade to stop before touching the cut-off piece. The operator should always be sure to return the cutter-head 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.
Fig. 54
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 cross­cutting except that the track arm is first positioned to the desired angle on the miter scale before it is clamped in place. 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. 54, shows a typical miter cutting operation on the radial saw.

21
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. 55, shows a compound miter cutting operation on the radial saw.
RIPPING
IMPORTANT: In certain applications it may be necessary
to use two push sticks, and/or featherboards. Also, if a push stick or other feeding device is necessary to assist in the feeding of material, make certain it is conveniently located so it may be reached easily without having to stretch or reach near the blade.
Ripping involves making a lengthwise cut through a board along the grain. When ripping, the track arm is clamped at “0” on the miter scale. The yoke is then positioned and clamped so that the blade is parallel to the fence. 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 in-feed side until it almost touches the workpiece, as shown in Figs. 56 and 57, to act as a holddown. The splitter and anti-kickback fingers (A) Fig. 56, should be adjusted as described under the section “ADJUSTING SPLITTER AND ANTI-KICKBACK FINGERS” in this manual. The operators 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. 58, to push the work between the fence and blade. The workpiece must have one straight edge to follow the fence. If board is bowed, place hollow side down. The cutting-head clamp knob should be securely tightened for all ripping operations.
WARNING:THE MATERIAL MUST NEVER BE FED
INTO THE OUTFEED END OF THE BLADE GUARD.
OUT-RIPPING
Out-ripping involves all of the general conditions stated above. The yoke is clamped at right angle to the track arm with the blade guard facing the front of the machine. The cutting-head 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. 56, shows a typical out-ripping operation on the radial saw.
IN-RIPPING
In-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 rear of the machine. The cutting-head 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. 57, shows a typical in-ripping operation on the radial saw.
WARNING: WHEN RIPPING WORK LESS THAN FOUR INCHES WIDE, A PUSH STICK SHOULD BE USED TO COMPLETE THE FEED (SEE FIG. 58)
