Blade Tracking

Perform this adjustment if the blade tracking does not
match the tracking shown Figure 25. In this procedure
you will tilt the upper wheel in or out slightly so the
blade tracks slightly to the front of the rubber tire center
line.
To adjust the wheel tilt and center the blade on the
wheel crown, do these steps:
1. DISCONNECT THE BANDSAW FROM POWER!
2. Open the wheel door and move the blade guide
blocks out of the way of the blade. (See Page 20 for
instructions on adjusting blade guides).
3. Turn the blade tension knob until there is moderate
tension on the blade.
4. Spin the upper wheel by hand at least three times
and watch how the blade rides on the crown of the
wheel. Refer to Figure 26 for an illustration of this
concept.
— If the blade rides in the center of the upper wheel
and is centered on the peak of the wheel crown,
then the bandsaw is already tracked properly and
no further adjustments are needed at this time.
— If the blade does not ride in the center of the
upper wheel and is not centered on the peak of
the wheel crown, then continue with the follow-
ing steps.
5. Loosen the tracking knob wing nut shown in Figure
27.
6. With one hand, spin the upper wheel clockwise.
With the other, rotate the tracking knob clockwise
slightly to move the blade to the rear of the wheel.
Turn the tracking knob counterclockwise to move
the blade to the front of the wheel.
7. Repeat Steps 4 & 5 until the blade tracks slightly to
the front of the rubber tire center line as shown in
Figure 25.
8. Tighten the tracking knob wing nut, readjust the
blade-guide blocks, and close the wheel door.
