Blade Tracking

The blade tracking is primarily affected by the tilt of the upper wheel, also known as "center tracking"; and the alignment of both wheels, also known as "coplanar track- ing." (For coplanar tracking, refer to the Wheel Alignment instructions on Page 52.)

The wheels on this bandsaw were aligned at the factory, so center tracking is the only adjustment that needs to be performed when the saw is new.

To center track the blade, do these steps:

1.DISCONNECT BANDSAW FROM POWER!

2.Make sure the upper and lower blade guides are adjusted away from the blade (refer to Adjusting Blade Guide Bearings on Page 23).

3.Move the quick tension lever to the tightened position (Figure 18) and turn the blade tension handwheel (Figure 17) until the blade tension matches the mark on the blade tension scale for the appropriate blade width (refer to Page 22 to tension the blade).

4.Open the upper wheel cover, then spin the upper wheel by hand at least three times and watch how the blade rides on the crown of the wheel through the tracking window. Refer to Figure 19 for an illus- tration 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 center tracked properly and no further adjustments 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 follow- ing steps.

5.Loosen the lock lever (Figure 18) so that the blade tracking knob can rotate.

6.Spin the upper wheel with one hand and rotate the blade tracking knob with the other hand to make the blade ride in the center of the bandsaw wheel tire.

7.Tighten the lock lever and close the upper wheel cover. Note: For the best performance from your

saw, regularly maintain proper tracking of the

blade.-17-
