Keep in mind that too much or too little blade

tension can cause blade breakage and/or poor

cutting performance.

If the band saw is to be idle for a period of time,

release tension on the blade – this will prolong

blade life.

Blade Tracking

Blade tracking has been tested at the factory but

should be checked as the machine receives

use, and after each blade change.

1. Disconnect machine from power source.

2. Move the upper and lower blade guides

away from the blade (see “Blade Guides”).

3. Open the top blade wheel door.

4. Rotate upper blade wheel by hand,

observing the position of the blade as it

rides upon the wheel. The blade should run

next to, but not against, the flange at the

rear of the wheel. Constant contact with the

flange will eventually damage the flange.

5. If the blade tracks improperly, use the

screws at the back of the saw (Figure 6) to

adjust the model 8014FW. Loosen the

socket head cap screws as needed to allow

adjustment of the set screws.

[Model 8020 FW: Use the tracking knob at

the back of the machine, shown in Figure 7.]

IMPORTANT: Tracking adjustments are

sensitive; make them in small increments and

allow the blade time to react to the changes.

6. When satisfied, return the upper and lower

blade guides close to the blade.

7. Close upper door, reconnect Band Saw to

power, and run it for a few moments. Make

any further tracking adjustments as needed,

with the machine disconnected from power.

Blade Guides

Blade guides must be

properly adjusted or damage may occur to

the blade and/or guides.

1. Loosen the two socket head cap screws on

the guide housing. See Figure 8.

2. Position the guide support in accordance

with the width of the blade. The blade

guides must be adjusted far enough back to

clear the blade even during the cutting

operation when the blade is deflected

toward the rear. The front end of the blade

guides should be adjusted approximately

1/8” behind the blade teeth. See Figure 8.
