6. Adjust the tracking set screw, as shown in
Figure 53, then tighten the lower hex bolt
loosened in Step 4.
— Tightening the tracking set screw will
move the blade closer to the shoulder of
the wheel.
— Loosening the tracking set screw will
move the blade away from the shoulder.
7. Tension the blade.
8. Reconnect the power and turn the bandsaw
ON.
— If the blade tracks along the shoulder of
the wheel (without rubbing), the blade is
tracking properly and this adjustment is
completed.
— If the blade walks away from the shoulder
of the wheel or hits the shoulder, turn the
bandsaw OFF, disconnect it from power,
then repeat Steps 4–8.
9. Turn the bandsaw OFF, disconnect it from
power, then replace the blade guard and
wheel access cover.
5. Use the blade tension knob to release the
blade tension, as shown in Figure 53.

! The blade guide bearings must be properly
adjusted to make square cuts. One bearing on
each assembly has an eccentric bushing that
allows it to be adjusted to properly support the
blade. The bearings are secured in place by a hex
nut and lock washer, as shown in Figure 54.

To adjust the blade guide bearings:
1. DISCONNECT BANDSAW FROM POWER!
2. Position the saw in the vertical position (see
Vertical Operation on Page 30 for more
information).
3. Loosen the hex nuts that secure the eccentric
bushings attached to the guide bearings.
4. Adjust the eccentric bushing as necessary so
that it pushes against the blade just enough
to hold the blade flat between the bearings.
Note: Since the bearings twist the blade
into position, it is acceptable if there is
0.001"–0.002" gap between the blade and
the front or back of the bearing. Just make
sure not to squeeze the blade too tightly with
the bearings. After the guide bearings are
set, you should be able to rotate the guide
bearings (although they will be stiff) with
your fingers.
5. Adjust the backing bearing in the same
manner, but leave a gap between 0.002–
0.003" from the back of the blade.
