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.
ADDITIONAL SAFETY RULES FOR RADIAL ARM SAWS WARNING: FAILURE TO FOLLOW THESE RULES MAY RESULT IN SERIOUS PERSONAL INJURY. 1. DO NOT OPERATE THIS MACHINE UNTIL it is assembled and installed according to the instructions. 10. KEEP ARMS, HANDS, AND FINGERS away from the blade. 2. OBTAIN ADVICE from your supervisor, instructor, or another qualified person if you are not familiar with the operation of this machine. 12. NEVER PERFORM a “crossed arm” operation. 11. NEVER REACH around the saw blade. 13.
POWER CONNECTIONS A separate electrical circuit should be used for your machines. This circuit should not be less than #12 wire and should be protected with a 20 Amp time lag fuse. If an extension cord is used, use only 3-wire extension cords which have 3prong grounding type plugs and matching receptacle which will accept the machine’s plug.
CHANGING VOLTAGE CURRENT CARRYING PRONGS The motor supplied with your saw is wired for 120 volt operation. If you desire to operate your saw at 240 volts, it is necessary to reposition voltage changing switch in the motor junction box (B) Fig. D. Proceed as follows: 1. WARNING: DISCONNECT TOOL FROM POWER GROUNDED OUTLET BOX SOURCE. 2. Remove screw (A) Fig. D, and remove nameplate cover (B). 3. Carefully slide switch (C) Fig. E, in motor junction box to read 240.

4. Loosen cutting-head clamp knob (S) Fig. 33, and slide cutting-head (T) the entire length of track arm (A) as shown to determine if blade (C) travels parallel to the square (E). A S C T E Fig. 33 5. If an adjustment is necessary, loosen index ring locking screw (J) Fig. 34, and track arm clamp handle (K). 6. Rotate track arm (A) Fig. 33, until blade (C) travels parallel to square (E). Then tighten track arm clamp handle (K) Fig. 34. J K Fig. 34 L K 7. With track arm clamp handle (K) Fig.
REMOVING “HEELING” IN SAW BLADE CUT Even though the cutting-head 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. 37. This condition is known as “heeling.” To check and adjust, proceed as follows: 1. DISCONNECT MACHINE FROM POWER SOURCE. 2. Install saw blade without guard. Fig. 37 3. Replace the fence with a flat piece of 3/4" wood (A) Fig. 38, at least 5" high. Tighten table board clamps. 4.
5. Place a square (D) Fig. 41, on the table and against the saw blade, as shown, and check to see if the blade is square with the table. NOTE: The square should rest between two teeth of the saw blade. 6. If an adjustment is necessary, make certain bevel clamp lever (C) Fig. 40, is tight. Remove screw, flat washer, and pointer (E) Fig. 40. Remove two screws (F) Fig. 40, and bevel scale plate (H) Fig. 42, with index knob (A). D 7. Loosen four hex head screws (G) Fig. 42.
ASSEMBLING BLADE AND BLADE GUARD TO MACHINE A 1. DISCONNECT MACHINE FROM POWER SOURCE. USE ONLY 10" BLADES WITH 5/8" ARBOR HOLES AND RATED FOR 5000 RPM OR HIGHER. 2. Assemble the inside (thick) arbor flange (A) Fig. 44, onto the arbor shaft with the recessed side of flange (A) facing out. 3. With the blade guard (B) Fig. 45, in the left hand, insert saw blade (C) into the blade guard (B) and onto the arbor shaft. Fig. 44 4. Assemble the outside (thin) blade flange (D) Fig.
CUTTING INTO TABLE BOARDS G B C 1. Assemble table boards (A) Fig. 48, and fence (B) as shown and secure in place with table clamps, one of which is shown at (C). A 2. Return cutting-head (D) Fig. 49, to rear of track arm (E), and tighten cutting-head clamp knob (G) Fig. 48. Make sure switch (H) Fig. 49, is in the “OFF” position and connect saw to power source. Fig. 48 K E 3. While holding cutting-head handle (L) Fig.
OPERATING CONTROLS AND ADJUSTMENTS STARTING AND STOPING RADIAL ARM SAW The on/off switch (A) Fig. 56, is located at the front of the cutting-head. To turn the saw “ON” move the switch (A) Fig. 56, up to the “ON” position. To turn the saw “OFF” move the switch (A) Fig. 56, down to the “OFF” position. A Fig. 56 LOCKING SWITCH IN THE “OFF” POSITION IMPORTANT: When the machine is not in use, the switch should be locked in the OFF position using a padlock (D) Fig.
5. Using a 3/16" Allen wrench (J) Fig. 64, turn adjustment screws (K) Figs. 61 and 64 to remove all “play.” NOTE: DO NOT OVERTIGHTEN ADJUSTMENT SCREWS (K). THIS CAN DAMAGE BEARINGS. K J WARNING: DO NOT LOOSEN ADJUSTMENT SCREWS (K) MORE THAN 1/2 TURN. THE CUTTINGHEAD MAY FALL FROM THE TRACK ARM. K 6. Tighten two hex nuts which were loosened in STEP 4, and check cutting-head travel for any “play” and to ensure it moves freely and smoothly. 7.
3. Rotate hex bolt (B) Fig. 67, in the desired direction which the handle needs to be turned. 4. Push hex bolt (B) Fig. 67, back through hole. Make certain head of hex bolt is seated properly in recessed bushing (C), and reassemble track arm clamping lever. NOTE: If track arm clamping lever (A) Fig. 66, tightens before approximately four turns, it is possible the clamping bushings, one of which is shown at (C) Fig. 67, may have rotated. These bushings should be seated completely inside track (D) as shown.
POSITIVE STOP YOKE INDEX Yoke index lever (A) Fig. 71, activates a positive stop which positions the cutting-head in the cross-cut or rip position. To rotate the cutting-head, release yoke clamp handle, press up or down on yoke index lever (A), releasing the positive stop, and rotate the cutting-head to the #1 in-rip or #2 out-rip or #3 cross-cut positions as desired. Release the yoke index lever (A) Fig. 71, and the cutting-head will automatically index at each of the three positions above. A Fig.
EXPLANATION OF OPERATING CONTROLS The following is an explanation of the operating controls of the Delta 10" Radial Saw. We suggest you study these explanations carefully to familiarize yourself with the controls before turning on the power. Doing otherwise may cause damage to the saw or personal injury (Figs. 74 and 75). B C K A. TABLE CLAMP KNOBS. Allows the operator to quickly set the desired fence position. Fig. 74 B. TRACK ARM INDEXING RELEASE HANDLE.
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 1/4" plywood 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.
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. 79, 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.
MAINTENANCE OVERLOAD PROTECTION The motor on your saw is equipped with a resettable overload relay (A) Fig. 82. If the motor shuts off or fails to start due to overloading, or low voltage, turn the switch to the “OFF” position, let the motor cool three to five minutes then push the reset button (A). The motor can then be turned on again in the usual manner. Some conditions that may cause overloading are; cutting stock too fast, using a dull blade, using the saw beyond its capacity, etc. A Fig.
CONSTRUCTING A PUSH STICK 28 Fig. 83 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. 82.
