SECTION 5: ADJUSTMENTS
TrackingTension
To adjust the tracking:
1.Disconnect the bandsaw from the power source and open the top and bottom wheel covers. Adjust the upper and lower guide assemblies away from the blade.
2.Loosen the lock nut on the tracking knob. See Figure 3. Rotate the upper wheel by hand and adjust the tracking knob (turn the tracking knob clockwise to track the blade in, counterclockwise to track out) until the flat body of the blade tracks in the center of the upper wheel. Turn the wheel at least three full turns to ensure that the blade is tracking in its final position.

Use extreme care when turning the bandsaw wheel. The upper wheel may have sharp edges and any procedures which require work in close proximity to the bandsaw blade could result in serious injury.
Final blade tension ultimately depends on the type and size of blade you use. To adjust the ten- sion:
1.Raise the blade guard to its fully retracted position.
2.Press, with moderate pressure, on the face of the blade with your thumb.
3.Turn the tension wheel until the blade deflects about 1/4". See Figure 4.
4.Make the other adjustments to the saw and test run it. If the blade is not cutting proper- ly, the tension may need to be increased. Remember, thin blades require less tension than wide blades.
5.Reduce the blade tension when the band- saw is not in use. This will help prevent pre- mature wear or breakage of the blade and/or rubber tires.
