Blade Tracking

A blade that is tracking correctly runs cooler, reduces wear-and-tear on the machine, and increases cutting performance. When tracking correctly, the blade rides next to, but not against, the wheel flange. The tracking is controlled by adjusting the upper wheel.

To adjust the upper wheel for blade tracking:

1.DISCONNECT BANDSAW FROM POWER!

2.Make sure the blade guides are adjusted away from the blade so they will not interfere with the change of blade position.

3.Ensure that the blade is correctly tensioned.

4.Using a 6mm hex wrench, loosen the four locking cap screws (see Figure 45).

5.Use a 5mm hex wrench to adjust the four set screws (Figure 45) to tilt the upper wheel in or out and bring blade tracking back to normal. Only adjust each screw in small increments.

6.Rotate the upper wheel by hand a couple times in the normal direction of rotation. Verify that the blade tracks next to, but not against, the wheel flange. Repeat Steps 5–6if necessary until the blade tracks correctly.

7.Tighten the locking cap screws and recheck the tracking to make sure it did not change. If it did, repeat Steps 4–7.

8.Adjust the blade guides back to their correct position.

Table Calibration

To ensure the accuracy of angle cuts and compound angle cuts, the scale pointers must point to zero when the table is perpendicular or 90° to the blade.

To calibrate the table to zero:

1.DISCONNECT BANDSAW FROM POWER!

2.Make sure the blade tracking and tension are set correctly.

3.Using a 6mm hex wrench, loosen the trunnion cap screws (see Figure 46).
