Keep the saw blade sharp and very little pressure will be required for average cutting Avoid twisting the blade by turning abrupt corners CUTTING CURVES When cutting curves turn the stock carefully so that the blade may follow without being twisted If a curve is so abrupt that repeated new kerfs are needed then use either a narrower blade or one that has more set The more set a blade has the easier the stock is to turn However the cut is usually rougher than when using a medium set When withdrawing the blade be careful not to draw the blade off of the wheels In most cases it is easier and safer to turn the workpiece and saw out through waste material Do not back the blade out while the saw is running SUGGESTED METAL CUTTING BLADES AND SPEEDS UNDER 1 4 1 TO 1 AND UP MATERIAL TEETH FPM TEETH FPM TEETH FPM STEELS PER PER PER INCH INCH INCH Angle Iron 24 160 14 160 Armor Plate 18 40 14 40 10 40 Carbon Steel 24 85 14 60 14 40 Chromium Steel 24 18 85 14 60 14 40 Cold Rolled Steel 24 18 220 14 220 14 160 Drill Rod 14 85 14 60 Graphite Steel 18 60 14 40 14 40 Hidfh speed Steel 24 85 14 60 14 40 Machinery Steel 18 160 14 160 14 160 Molybenium Steel 18 85 14 60 14 40 Nickel Steel 18 40 14 40 14 40 Silicon Manganese 18 85 14 85 14 60 Stainless Steel 24 40 14 40 10 40 Structural Steel 24 160 14 160 14 115 Tungsten Steel 18 40 14 40 10 40 FOUNDRY METALS Brass hard and soft 18 335 14 33

Use these graduations until you become familiar enough with the operation of the band saw to vary the tension for different kinds of blades or work IMPORTANT OVER STRAINING is a common cause of blade breakage and other unsatisfactory blade performance Release the blade tension when the machine is not in use TRACKING THE BLADE DISCONNECT MACHINE FROM POWER SOURCE IMPORTANT Before tracking the blade be certain that the blade guides and blade support bearings do not touch the blade After applying tension to the blade rotate the wheels slowly forward by hand and observe the blade s movement The blade A Fig 24 should travel just to the front of the center of the upper tire If the blade creeps toward the front edge loosen the wing nut B Fig 25 and tighten the thumb screw C This will draw the blade toward the center of the tire If the blade creeps toward the back edge turn the thumb screw in the opposite direction Adjust the thumb screw C Fig 25 only a fraction of a turn each time NEVER TRACK THE BLADE WHILE THE MACHINE IS RUNNING After the blade is tracking just to the front of the center of both tires tighten the wing nut B Fig 25 Adjust the Blade Guides and Bearings VERTICAL ADJUSTMENT OF THE UPPER BLADE GUIDE ASSEMBLY NINE DISCONNECT MACHINE FROM POWER SOURCE Set the upper blade guide assembly A Fig 26 as close as possi ble to the top surface of the workpiece Loosen the lock knob B and move the guide ass
