Rotate blade guard (B) Fig. 47, to the rear and tighten arbor nut (E) using two wrenches (G) supplied. D E 7. Rotate blade guard (B) Fig. 46, to the horizontal position and tighten clamp knob (H). IMPORTANT: CLAMP KNOB (H) FIG. 46, MUST BE TIGHT AND BLADE GUARD SECURE DURING OPERATION. C Fig. 45 H NOTE: The lower retractable blade guard provides operator protection in an axial direction to the saw blade. Care must be taken to eliminate potential hazards of the lower blade guard. B F A) KEEP YOUR HANDS AWAY FROM THE GUARD. As the blade cuts, the guard will lift and leave part of the blade exposed. B) SHUT OFF POWER BEFORE FREEING A JAMMED LOWER GUARD. The guard can get jammed in previous kerfs in table or fence. Always anticipate the path of the guard. Fig. 46 B C) USE CAUTION when making bevel cuts to be sure the lower guard is never pinched towards the blade. D) THE LOWER GUARD CAN JAM AGAINST THE FENCE DURING NARROW IN-RIPS. Should the guard jam against the fence, disconnect the saw from power, wait for the blade to stop, then lift the blade guard and rest it on top of the fence. G E Fig. 47 18 FASTENING SAW TO THE FLOOR If during operation there is any tendency for the saw to tip over, slide, or walk on the supporting surface, the saw should be secured to the floor surface through holes provided on the bottom of each leg. CUTTING INTO TABLE BOARDS G 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). B C 2.

The motor on your saw is shipped from the factory wired for 120 volt operation. The motor has a built in brake which automatically stops the blade within seconds after turning off the saw or when power is lost. C Fig. 57 B A ADJUSTING BALL BEARINGS AGAINST TRACK C The cutting-head (C) Fig. 61, is suspended from four pre-loaded, lubricated, shielded ball bearings, two of which are on fixed shafts at (A) , and two on adjustable shafts at (B). NOTE: CUTTING-HEAD (C) FIG. 61, IS REMOVED FROM TRACK ARM FOR ILLUSTRATION PURPOSES ONLY. DO NOT REMOVE CUTTING-HEAD FROM TRACK ARM! K B Fig. 61 After extended use, wear may develop in the track arm, causing “play” between the ball bearings and the track. The ball bearings must ride smoothly and evenly in the channels of the track arm. Adjustment to the two bearings on adjustable shafts can be made as follows: D G E 1. DISCONNECT TOOL FROM POWER SOURCE. 2. Remove plastic plug (D) Fig. 62, from the top of track arm (E). Fig. 62 H 3. Slide cutting-head (C) Fig. 63, until one of the adjustable bearings (B) Fig. 60, are visible through hole (G) Figs. 62 and 63. G 4. Using a 1/2″ socket, extension, and ratchet (H) Fig. 63, through hole (G) in track arm, slightly loosen hex nut on adjustable shaft (B) Fig. 61, approximately 1/8 turn. Repeat procedure for other bearing. C 20 Fig. 63 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 WARNING: DO NOT LOOSEN ADJUSTMENT SCREWS (K) MORE THAN 1/2 TURN. THE CUTTINGHEAD MAY FALL FROM THE TRACK ARM. K J 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. When adjustments are complete, replace plastic plug which was removed in STEP 2. Fig. 64 ADJUSTING TENSION ON ELEVATING COLUMN Elevating column tension is preset at the factory. It can be adjusted to remove any “play” which may develop after extended use. Adjustments can be made as follows: H F 1. DISCONNECT TOOL FROM POWER SOURCE. C E 2. Loosen hex nuts (A) Fig. 65, and gib adjustment screws (C). D A C B 3. Adjustment to column base (B) Fig. 65, is made by loosening hex nuts (D) and turning screws (E) until column base wraps around column securely and can be raised or lowered without binding. Then tighten hex nuts (D) against column base. 4. After all movement between column base (B) Fig. 65, and elevating column (F) is removed, tighten gib and adjustment screws (C) against gib (H) until all side-toside play is removed. Then tighten hex nuts (A) against column base. NOTE: After adjusting column tension, refer to “ADJUSTING SAW BLADE TRAVEL SQUARE WITH FENCE” to determine if saw blade travel was affected. Fig. 65 CHANGING POSITION OF TRACK ARM CLAMPING HANDLE When the track arm clamping handle (A) Fig. 66, does not lock in a convenient position, it may be repositioned as follows: A 1. DISCONNECT TOOL FROM POWER SOURCE. 2. Loosen and remove track arm clamping lever (A) Fig. 66, and push hex bolt (B) Fig. 67, back through hole until head of bolt is out of the recessed bushing (C) as shown. NOTE: Track arm clamping lever has left hand thread. Fig. 66 21 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. If they are not, slightly loosen clamping lever (A) Fig. 66, and rotate clamping bushing (C) Fig. 67, until it seats properly into track (D) as shown. It may be necessary to rotate bushing on clamp lever side also. Fig. 68, illustrates track arm clamping lever assembly unassembled for illustration purposes only. The flats (E) Fig. 68, on clamping bushings (C) should face the front of saw. D B C Fig. 67 NOTE: Clamp lever (A) Fig. 68, will begin to thread at one of two positions. If after making the adjustment the clamp lever (A) tightens 180 degrees from where desired, slowly unscrew clamp lever (A) while holding in on hex bolt (B). When the clamp lever (A) comes off hex bolt (B), rotate clamp lever (A) 180 degrees. Then start to tighten clamp lever (A). E B A C CHANGING POSITION OF BEVEL CLAMP HANDLE When the bevel clamp handle does not lock in a convenient position, it can be repositioned as follows: 1. Fig. 68 DISCONNECT TOOL FROM POWER SOURCE. 2. Loosen bevel clamp handle (A), release bevel index release knob (B), and turn motor (C) to vertical position as shown in Fig. 69. NOTE: IF BLADE GUARD CONTACTS TABLE SURFACE, RAISE TRACK ARM.

Fig. 69 CHANGING POSITION OF YOKE CLAMP HANDLE A When the yoke clamp handle (A) Fig. 70, does not lock in a convenient position, it can be repositioned as follows: 1. DISCONNECT TOOL FROM POWER SOURCE. 2 Remove retaining ring (B) Fig. 70. B 3. Reposition yoke clamp handle (A) Fig. 70, on hex clamp nut. 4. Replace retaining ring (B) Fig. 70. Fig. 70 22 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. 71 POSITIVE STOP BEVEL INDEX B Bevel index knob (A) Fig. 72, provides a positive stop when positioning the saw blade at zero, 45°, and 90° left, and 90° right on the bevel scale (C). To change the angle of the saw blade, loosen bevel clamp handle (B), pull out bevel index knob (A) and tilt saw blade and motor. For zero, 45°, and 90° left, and 90° right positions, release bevel index knob (A) and saw blade will index at each of these positions. Then tighten bevel clamp handle (B). For saw blade angles between positive stops, set blade at desired angle on bevel scale (C) and tighten bevel clamp handle (B) Fig. 72. A C Fig. 72 ADJUSTING SPLITTER AND ANTI-KICKBACK FINGERS During ripping operations, the splitter (A) Fig. 73, must ride in the saw kerf and the anti-kickback fingers (B) should be touching the workpiece to prevent kickback. 1. Set the saw up in the ripping position with the blade guard lowered on the in-feed side to act as a holddown. 2. Start a piece of material through the saw as shown in Fig. 73. C A 3. Shut off saw and disconnect from power source. B 4. Adjust the arm (C) Fig. 73, so that it is vertical and the splitter (A) is in the saw kerf. 5. If the splitter (A) Fig. 73, does not line up with the saw kerf, loosen hex nuts (D), and position splitter (A) into saw kerf as shown. Then tighten hex nuts (D) against arm (C). The straight side of the splitter should be toward the blade as shown in Fig. 73, and the anti-kickback fingers should rest on the workpiece as shown. NOTE: The clamp knob for arm (C) must be tight. Move arm (C) front to back while tightening clamp knob with other hand to be sure clamp is firmly seated and tight. D Fig. 73 6. Pull backward on the workpiece to determine if the anti-kickback fingers bite into the material and prevent further backward movement. If necessary, readjust height of arm (C) Fig. 73. 23 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. 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 readily be replaced as often as is necessary to protect the table boards and to insure accurate and safe work. 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 The first operation which should be learned on the radial saw is cross-cutting (Fig. 74). 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 across 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. 74 CROSS-CUT STOP A block of wood placed at (B) Fig. 74A 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. T B Fig. 74A 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. 75, shows a typical miter cutting operation on the radial saw. Fig. 75 24 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. 76, shows a compound miter cutting operation on the radial saw. Fig. 76 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. A 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 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 in-feed side until it almost touches the workpiece, as shown in Figs. 77 and 78, to act as a holddown. The splitter and anti-kickback fingers (A) Fig. 77, 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. 79, 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. Pay particular attention to warning label (B) Fig. 78, which states that material must never be fed into the outfeed end of the blade guard. Fig. 77 B Fig. 78 OUT-RIPPING IN-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. 77, shows a typical out-ripping operation on the radial saw. 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. 78, 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. 79) 25 CONSTRUCTING A PUSH STICK 26 Fig. 79 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. 79.
