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 (Figure 39).

5. Use a 5mm hex wrench to adjust the four set
screws (Figure 39) 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 5-6
if 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 (Figure 40).
4. Place a machinist's square on the table and
against the side of the blade, as shown in
Figure 41.
