6. Rotate upper wheel by hand several times
and watch how blade rides on wheel (see
Figure 17 on Page 17 for an illustration of
this concept).
— If the blade rides in the center of the upper
wheel, it is properly tracking and you are
done with this procedure—proceed to
Dust
Collection on Page 19.
— If the blade does not ride in the center of
the upper wheel, it is not properly tracking;
continue with the next step to adjust it.
7. Spin upper wheel with one hand and slowly
adjust tracking knob (see
Figure 19) with
other hand until blade consistently tracks in
center of wheel.
8. Close and secure upper wheel cover before
operating bandsaw.
To adjust blade tracking:
1. DISCONNECT MACHINE FROM POWER!
2. Adjust upper and lower blade guides away
from blade and raise upper guides all the
way up (refer to
Adjusting Blade Guide
Bearings on Page 23 for detailed instruc-
tions).
Note: When adjusting the blade tracking for
the test run in this procedure, the blade must
have approximately the same amount of ten-
sion as when under operating conditions.
After the test run is successfully completed,
you will be instructed on how to more accu-
rately tension the blade for optimum results.
3. Move quick-release lever all the way clock-
wise (as viewed from the rear of the machine)
to apply tension to blade (see
Figure 19).
4. Open upper wheel cover.
5. Rotate tension adjustment knob clockwise
until there is approximately
1
⁄
4
" deflection in
blade when pushed with moderate pressure.
