6.1.3 Blade Tracking
After proper tensioning, the blade must be tracked. Tracking refers to the position of the
blade on the wheels while the machine is in operation. Tracking should be checked
periodically, and is mandatory after every blade change. Blade tracking is done by hand with
the machine disconnected from the power source.
Fig. 9
Refer to Figure 9.
1. Disconnect the machine from the power source.
2. The blade must be correctly tensioned.
3. Make sure the blade guides and other parts of the machine will not interfere with the
blade movement. Lower the guide post until you can see the blade through the tracking
window.
4. Open the upper door to expose the wheel. Rotate the wheel by hand, observing the
position of the blade through the tracking window (C).
5. If the blade tends to move toward the edge of the wheel, loosen the locking knob (A) and
slightly rotate the tracking knob (B) while continuing to rotate the wheel.
6. Observe the blade through the tracking window. Rotating the knob clockwise will cause
the blade to move toward the rear edge of the wheel. Rotating the knob
counterclockwise will cause the blade to move toward the front edge of the wheel. This
adjustment is sensitive; perform it in small increments and give the blade time to react to
the changes.
7. When the blade is tracking in the center of the wheel, re-tighten the locking knob and
close the upper door.
8. Tension the blade and connect the band saw to the power source. Turn it on for a brief
time to observe the blade action through the tracking window.
9. If further adjustments are needed, disconnect from the power source and repeat the
above procedure.
