INSTALLATION OF SAW: There are four 5/16 diameter holes provided in the base of the saw through which the tool should be fastened securely with screws or bolts to a well built work bench. A large hole in the bench below the blade will allow sawdust to escape. The Motor Mount Bracket should be installed as shown in Fig. 2. I. Set the saw at 0 inches elevation and 0 degrees tilt. (See paragraph headed "Controls".) ASSEMBLY: Fence and Miter Gage Install as shown in Fig. I. Motor Alignment Rod The 5/1 6 x 4 1/2 inch motor alignment rod, No. I 7, fits into the hole in the back of the splitter bracket. Insert the rod as far as it will go into the bracket and tighte:n the set screw. 2 FIGURE 2 r · 2. Draw a line on the bench 5 inches from the rear of the Saw base. (Measure at two points 12 inches apart to be sure that the line is parallel to the rear of base. ) 3. Place the bracket, No. 22, on the bench as follows; The end with the elongated hole 4 5/8 inches in from the left side of saw base and the front edge on the line drawn previously. Fasten it securely in this position. 4. Assemble motor rail, No. 2 I, and motor rail guide and plate, No. 18, to the motor rail bracket as shown. The grooved end of the motor rail to be placed in end of bracket with elongated hole. 5. Bolt your motor to the mount so that the motor pulley will be in line with the saw pulley when the motor alignment rod is through the slot in the motor rail guide and plate. Check before Operation I 1. The motor alignment rod must project at least 1/4 inch through the mount slot with the blade retracted and tilted 45 degrees. This setting should be checked often during operation. As the belt wears or stretches, loosen the set screw and pull the alignment rod out of the bracket the amount needed. 2. The motor mount must not strike the motor mount bracket at either end of the motor rail at 0 or 45 degrees tilt. 3. Be sure that the teeth of the blade point toward the front of the saw and the top of the blade turns toward the front. MOTO,,: For general home workshop use, a 1/2 horsepower 3450 RP.M. motor will provide adequate speed and power. However, to enable you to take full advantage of the rugged performance features and full cutting efficiency of this saw, especially for heavy duty work, a 3/4 horsepower 3450 RP.M. motor should be used. SPEED: The motor pulley, No. 64, installed on a 3450 RP.M. motor with a 1/2 inch diameter shaft will drive the saw at the recommended speed-4500 RP.M. 3. The elevation screw, No. 76. 4. The motor rail, No. 21. CONTROLS: The Control Knob raises the saw from 0 to 2 1/2 inches above the table level when pushed in and turned. It tilts the saw 0 to 45 degrees when pulled out and turned. The Angle of Tilt is shown by a pointer on the scale just below the control knob. The Depth of Cut Gauge and Pointer c~n be seen through the curved slot to the left of the control knob. The Miter Protrador face is a guide surface for. cross cutting or diagonal cutting to a definite angle. The protractor may be used on either side of the blade at any angle or depth of cut setting. The angle is shown by the pointer on the calibrated scale on the protractor head. The lock knob clamps the head in the selected position. CAUTION: This saw has an extra long spindle for greater dado capacity. If the blade is extended more than 2 3/8 inches according to the depth of cut gauge, the spindle will strike the table insert when the saw blade is tilted. The Fence Lock Handle when down clamps the fence at both ends of the table. Raise the handle to unlock and by grasping the front fence end move the fence to any point across the table. T~ make sure that the fence~l!!rpendicular to the I!lbfe, push down on fence as you lock it. / TIGHTEN LOCK NUTS AFTER ADJUSTMENT FIGURE 3 BELT: If your motor shaft is approximately 4 inches from the bottom of the base of the motor, the V-belt, No. 62, should fit the installation previously described. LUBRICATION: The precision ball bearing assembly used on the saw arbor has been packed with lubricant and sealed at the factory. It should require no further attention for the life of the bearing assembly. To maintain the smooth, easy operation of the controls, oil the following points occasionally; 1. The guide, No. 48, at the front cif the arbor support. 2. The guide ways of the front and rear trunnions, Nos. 80 and 96. ADJUSTMENTS: The following items may require adjustment due to rough handling during shipment. The Blade Tilt Stop Screw, No. 103, located just behind the front trunnion on the left side of the body casting stops the tilt mechanism when the blade is at right angles to the table. The Pointer for the Tilt Scale should indicate 0 degrees when the blade is at right angles to the table. The Depth of Cut Pointer should be set at 0 when the blade is lowered with the teeth just flush with the table surface. The Elevation Limit Stop Nuts shown in Fig." automatically stop the saw at high (2 1/2 inch projection) and low position. The front pair of stops control the high position while the rear pair stop the blade at low position. 3 IAISE .LADE ,'AI INC"S DISTANCE'SHOULD BE EOUAL. TURN BLADEMEASURE FROM SAME TOOTH AT TABlE LEVEL FENCE MUST LOCK PARALLEL WITH MITER SLOTS FIGURE 4 The Blade Must Be Parallel with the Miter Slots in the Table to Get a Straight Cut. (See Fig. 4). Adjustment, if necessary, may be made as follows; 1. Raise the blade to 2 1/2 inches depth of cut and set at right angle (0 degrees) to table. 2. Measure accurately from a raker tooth on the blade to an edge of either miter slot, as explained and shown in Fig. 4. 3. Loosen the bolts, Nos. 79 and 97. holding each trunnion, Nos. 80 and 96. to the lower table surface. (4 bolts total.) 4. Shift the complete under-table mechanism until the blade is parallel with the miter slot. 5. Re-tighten the four trunnion screws. front pair first. 6. Check this adjustment as previously explained fa be eel lain it is correct-after re-assembly is complete. The Fence Must Lock Parallel with the Miter Slots. Using one hand on the front end of the fence, slide the fence to the edge of the miter slot. Push the lock handle down slowly. If fence isn't parallel to miter slot adjust as follows; 1. Loosen the two screws, NO.,1OS; ,on the under- side of the front fence end. ' 2. Release the fence lock handle. 3. Hold the fence flush to the edge of the miter slot. Turn both screws up just snug. Then tighten each one securely. 4. Check the adjustment by sliding the fence away from the slot and returning several times to see if it locks parallel each time. The Fence Must Be Square with the Table Surface. Adjust by loosening the screws, No. 10, holding the fence slide bar to the table. Slide the bar up or down at either end to square the face of the fence with the table. Re-tighten the screws. The Arbor Tilt Tension Spring, No. 100, provides tension to keep the mechanism tilted at any angle, thus eliminating the need for a manual control lock. After tlie,;tbol is "broken in." you may find it necessary to.lncr~~se this tension. Loosen the lock nut. No. 90. and turn the bolt, No. 101, until enough tension has been applied. Re-tighten the lock nut. Note: After a few hours of operation. tightep all pulley set screws. CARE OF THE BLADE: Keep the blade teeth sharp and properly set. To sharpen the blade; 1. Lower the blade until an oil stone laid on the table will just touch the teeth. Rotate the blade backward by hand until the ends of all the small cutting teeth have been touched. 2. File the gullets (space between teeth) of all teeth of the same shape to a uniform depth and width. Maintain' the original shape, bevels. and dimensions. Avoid sharp corners or nicks in the gullets between the teeth. 3. The top one-quarter of each cutting tooth should be set at an angle of approximately 10 degrees. The set should be uniform and should alternate from left to right on successive teeth. The large raker teeth require no set-they should be kept approximately 1/64 inch shorter than the cutting teeth. 4. File the bevel of each cuttingtooth-15 to 20 degree bevel on the inside front face of each tooth. Maintain the original bevel angle and be careful not to shorten the teeth. Blade Wobble is often noticed at slow speeds when starting or stopping the saw. If this does not disappear at full speed, check the saw blade and clamp washers for dirt or saw dust on the clamping surfaces. Gummy' residue can generally be removed with kerosene. ' OPERATION: - · < The blade provided with this saw may be used for Doth cross-cutling and ripping. For proper chip clearance and best general results, the blade should project through the work-piece ap- proximately 1/4 inch. Do not force material into the blade too fast. Use a straight, direct, steady feed which does not over- tax the cutting capacity of the blade. To eliminate creep of your work when making a miter cut, clamp the work piece to the.miter gage. Support long work as it leaves the.re~of the table. SAFETY: While the bench saw is one of the most widely used woodshop power tools, it is by nature of its general design. one of the most dangerous in the hands of , inexperienced or careless operators. The bench saw is not, however. an unsafe tool when used with common sense and good judgment. Use a push block rather than letting the hands get closer than 3 inches to the blade on narrow cuts. Never hold the hands over the blade when making blind groove type cuts. Stand to one side when completing a cut. A loose piece caught J.)ythe blade can fly back with surprising force. Always stop the saw when removing waste stock from near the blade, when making adjustments, or when changing settings. Donat wear dangling neck ties, loose baggy sleeves, etc.· while operating power tools. 17 16 /, 18 32_.~, ,....,/ _ ,/ j 317301 / l IJ 29 28 27 l1 ./ - /.--129 0 ·· I 25 23 24 26 MOTOR MOUNT COMPlETE 103 J-;- 102 41 55 FENCE ASSY.
