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.
