Changes in blade width and the type of material being cut will have an effect on blade tension.
Keep in mind that too little or too much blade tension can cause blade breakage and/or poor cutting performance.
TIP: When the band saw is not being used, slightly release the tension on the blade – this will prolong the blade’s life. Make a note of the specific tension setting for that particular blade, as shown on the gauge (D, Figure 14). The tension can then be
Blade Tracking
“Tracking” refers to the position of the saw blade on the wheels while the machine is in operation. Tracking has been
IMPORTANT: Make tracking adjustments with knob (F, Figure 15). DO NOT use screws (G, Figure 15); these were used by the manufacturer for wheel alignment and should NOT be used for blade tracking.
To inspect and adjust tracking, proceed as follows:
1.Disconnect machine from power source.
2.The blade must be properly tensioned before adjusting blade tracking. Make sure the blade guides and other parts of the machine will not interfere with the movement of the blade.
3.Open upper front door to expose the upper wheel. Rotate the wheel clockwise by hand, and observe the position of the blade on the wheel. The blade should ride upon the center of the wheel (Figure 16).
4.If the blade tends to move toward the edge of the wheel, loosen wing nut (E, Figure 15) and slightly rotate knob (F, Figure 15). Rotating the knob clockwise will cause the blade to move toward the rear edge of the wheel. Rotating the knob counterclockwise will cause the blade to move toward the front edge of the wheel.
NOTE: This adjustment is sensitive; perform it in small increments and give the blade time to react to the changes, as you continue to rotate the wheel.
5.When the blade is tracking properly in the center of the wheel,
6.Close upper front door.
