Blade Tracking

Disconnect machine from power source. Do not adjust blade tracking with the machine running.

“Tracking” refers to how the blade is positioned on the wheels while in motion. The blade should track approximately in the center of both wheels, as shown in Figure 44. Tracking on the PWBS- 14CS Band Saw has been factory-adjusted; however, it should be checked periodically, including after every blade change.

Refer to Figure 45.

1.The blade must be properly tensioned before adjusting blade tracking. Make sure blade guides and blade bearings do not interfere with the blade.

2.Place the tension lever at full tension position.

3.Open the upper door and rotate the upper wheel forward by hand. Observe the position of the blade on the wheel - it should be in the center.

4.If the blade tends to shift to one side or the other of the wheel, loosen wing nut (Figure 45).

5.If the blade is tracking toward the front edge of the wheel, rotate the tracking knob clockwise – the upper wheel will tilt toward the back and the blade will move to the center of the wheel.

If the blade is tracking toward the back edge of the wheel, rotate the tracking knob counterclockwise: the upper wheel will tilt toward the front and the blade will move to the center of the wheel.

IMPORTANT: This adjustment is sensitive; perform it in small increments and give the blade time to react to the changes, as you continue to rotate the wheel.

6.When blade is tracking properly at the center of the wheel, re-tighten the wing nut.

7.Turn on saw and verify proper tracking while the machine is running.

8.If further tracking adjustments are needed, disconnect from power, and repeat instructions above.
