Blade Tracking

To track the blade:

1.Unplug the bandsaw!

2.Adjust the upper and lower guide bearings and support bearings as far away as possible from the blade.

3.Open the upper wheel cover.

4.Spin the upper wheel by hand at least three times and watch how the blade rides on the crown of the wheel. Refer to Figure 7 for an illustration of this concept.

—If the blade rides in the center of the upper wheel and is centered on the peak of the wheel crown, then the bandsaw is already tracked properly and no further adjust- ments are needed at this time.

—If the blade does not ride in the center of the upper wheel and is not centered on the peak of the wheel crown, then continue with the following steps.

5.Loosen the lock knob on the tracking control knob threads, so that the tracking control knob will rotate for adjustments.

6.Spin the upper wheel with one hand and rotate the tracking control knob (Figure 8) with the other hand:

—If the blade rests too far back on the wheel, turn the tracking control knob counterclock- wise until the blade is tracking correctly.

—If the blade rests too far forward on the wheel, turn the tracking control knob clock- wise until the blade is tracking correctly.

7.Tighten the tracking control lock knob and close the upper wheel cover.

For the best performance from your saw, regu- larly maintain the proper tracking of the blade.

NOTICE

Changes in the blade tension may change the blade tracking.
