NOTICE
Changes in the blade tension may change
the blade tracking.
6. Loosen the lock nut on the blade tracking
knob threads so the blade tracking knob will
rotate for adjustments.
7. Spin the upper wheel with one hand and
rotate the blade tracking knob with the other
hand to make the blade ride in the center of
the bandsaw wheel tire.
8. When the blade consistently rides in the cen-
ter of the wheel, tighten the tracking control
lock nut.
9. Close the upper wheel cover.
Note: For the best performance from your saw,
regularly maintain proper blade tracking.
If, during the test run, you cannot easily locate
the source of an unusual noise or vibration,
stop the machine immediately, then review
Troubleshooting on Page 37.
If you still cannot remedy a problem, contact our
Tech Support at (570) 546-9663 for assistance.
To test run the machine:
1. Read the Safety section beginning on Page
6 and read Basic Controls on Page 24.
2. Connect the machine to the power source.
3. Turn the speed dial counterclockwise as far
as it will go.
4. Lift the STOP paddle on the power switch
and press the STOP button all the way in
(this resets the safety mechanism on the
STOP switch).
5. Turn the power ON by pressing the green ON
button above the STOP paddle. The digital
display should light up. If not, make sure the
power STOP switch has been reset; other-
wise, check the electrical connections and
power source.
6. Press the ON button located on the motor
control switch, then slowly turn the speed dial
clockwise.
7. Listen to and watch for abnormal noises or
actions. The machine should run smoothly
with little or no vibration or rubbing noises.
— Strange or unusual noises must be inves-
tigated and corrected before operating
the machine further. Always turn
OFF the
machine and disconnect it from power
before investigating or correcting potential
problems.
Wear safety glasses
during the entire test
run process. Failure to
comply may result in
serious personal injury.
Test Run
Once assembly is complete and you have per-
formed the
Blade Tracking steps on Page 17,
test run the machine before continuing with the
remainder of the adjustments.
