MAKE PROPER TOOTH SELECTION SELECTION For maximum cutting efficiency and lowest cost per cut, it is important to select the blade with the right number of teeth per inch (TPI) for the material being cut. The material size and shape dictate tooth selection. You need to consider: 1.The width of the cut. That is, the distance in the cut that each tooth must travel from the point it enters the workpiece until it leaves the workpiece, and 2.The shape of the workpiece. ® Squares, Rectangles, Flats (Symbol: №) Locate the width of cut on the chart. (Inches on the outer circle and millimeters on the inner circle.) Select the tooth pitch 28 27 76 29 24 23 22 29 21 20 1% 1% I% 2 y 74 3 » on the ring marked with the square shape which aligns with the width of cut. EXAMPLE: 6" (150mm) square, use a 2/3 Vari-Tooth. e Round Solids (Symbol: €) Locate the diameter of your workpiece on the chart. Select the tooth pitch on the ring marked with the round shape which aligns with the size of stock you are cutting. EXAMPLE: 4" (100mm) round, use a 3/4 Vari-Tooth. e Tubing, Pipe, Structurals( Symbol : OHA") Determine the average width of cut by dividing the area of the workpiece by the distance the saw blade must travel to finish the cut. Locate the average width of cut on the chart. Select the tooth Ditch on the ring marked with the tubing and structural shape which aligns with the average width you are cutting. EXAMPLE: 4" (100mm) outside diameter, 3"(75mm) inside diameter tubing. 4"(100mm) OD=12.5 sq.In. (79cm?) -3"(75 mm ) ID= 7.0 sq.In. (44cm?) Area = 5.5 sq.In. (35cm?) 5.5 sq.In.

BLADE GUIDE BEARING TR — = of ADJUSTMENT 9 Це ATTENTION: This is the most important Ti — adjustment on your saw. It is impossible to get satisfactory work from your saw If the fig 3. blade guides are not properly adjusted. The blade guide bearings on your metal. Cutting Band Saw are adjusted and power tested with several test cuts before leaving the factory to insure proper setting The need for adjustment should rarely occur when the saw is used properly. If the guides do get out of adjustment though, it Is extremely important to readjust immediately. If improper adjustment in maintained, the blade will not cut straight, and if the situation is not corrected it will cause serious blade damage. Because guide adjustment is a critical factor in the performance of your saw, it is always best to try a new blade to see If this will correct poor cutting before beginning to adjust. If a blade becomes dull on one side sooner than the other, for example, it will begin cutting crooked. A blade change will correct this problem the guide adjustment will not. If a new blade does not correct the problem, check the blade guides for proper j. FRONT AND REAR CUTTING OPERATION: FOR RF-712DR ONLY 1), For front cutting: an Push the vice base backward (far from you) to the end, fix the 3 vice base fix screws (A). Choose the swivel arm angle you need start cutting. 2), For rear cutting: — Push the vice base backward (close to you) to the end, fix the 3 vice base fix screws (A). | spacing. ENORME SELENA ONAeOs NOTE: There should be from 000 (just PEA touching) 001 clearance between the К. HOW TO OPERATE THE SWIVEL 9 : Ай CUTTING blade and guide bearings to obtain this clearance adjust as follows: 1. The inner guide bearing is fixed and cannot be adjusted. 2. The outer guide bearing is mounted to an eccentric bushing and can be adjusted. 3. Loosen the nut while holding the bolt with an Alien wrench. 1), Loosen the leaf screw (A) 2), Move the swivel bow by the hand, 4. Position the eccentric by turning the bolt to the desired position of clearance. 2. Tighten the nut. 6. Adjust the second blade guide bearing in the same manner. REMARK: 1. Adjust the tension of blade until the back of the blade (A) against the blade wheel (front) lightly. 2.Be sure the nut (E) is tightened. 3. Turn the eccentric shaft (B) counterclockwise, when the bearing (D) touches the saw blade properly, tighten the nut (E). 4 To adjust, loosen set screw (F) and move the blade adjustable up or down until 12. BLADE TRACK ADJUSTMENT (1). Open the blade guard. (2). Remove the blade guide assemblies (top and bottom) (3). Loosen the hex head screw in the tilting mechanism to a point where it is loose but snug. (4). With the machine running, adjust both the set crew and blade tension knob simultaneously to keep constant tension on the blade. The set screw and blade tension knob are always turned in opposite directions, ie, when one is turned clockwise the other is turned counterclockwise. it lightly touches the back of the blade (A). 5. Repeat 1. 2, 3, and 4 steps to adjust the other side's blade guide bearings (G). 6. Correct the base and blade to be a vertical position with a scale. If necessary, loosen set screw (F). 7. Set down the blade frame, correct the jaw vise (H) and blade to be a vertical position with a scale then tighten the set screws (1). 8. Loosen set screw (K), move front jaw vise (J) to against rear jaw vise (H) tightly. Finish correcting by tightening set screw(K). The blade is tracking properly when the back side just touches the shoulder of pulley or a slight gap appears near the center line of the pulley. Care should be taken not to over-tighten the saw blade since this will give a false adjustment and limit life of the blade. (9). Tighten the hex head screw in tilting mechanism. IMPORTANT: Sometimes in trying to make this critical adjustment it is possible to cause the basic setting to be misaligned. Should this occur, proceed as follows: a. Loosen the set screw and back it out as far as it can go and still remain in the threaded hole. b. Turn the hex head screw clockwise until it stops (do not tighten). c. Turn the set screw clockwise until it bottoms, then continue for half a turn and check the tracking by turning on the machine. d. If further adjustment is required, go back to step 4. (6). Turn off power to the machine. (7). Replace the blade guide assemblies--it may be necessary to loosen the blade tension slightly. (8). Adjust the vertical position of blade guide bearing assemblies so that the back side of the blade just touches the ball bearing. (9). Make a final run to check tracking. It required, touch up adjustment (See stop 4) (10). Replace the blade guards. 13.
