The rest of the adjustments in this section require you to start the bandsaw. Before starting the bandsaw, make sure you have performed the preceding assembly and adjustment instructions, and you have read through the rest of the manual and are familiar with the various functions and safe- ty issues associated with this machine. Failure to follow this warning may result in serious personal injury or even death!

Test Run

Turn on the power supply at the main panel. Push the START button to turn on the bandsaw. Make sure that your hand is poised over the switch in case there is a problem. The bandsaw should run smoothly with little or no vibration or rubbing nois- es. If strange or unnatural noises are immediate- ly apparent, press the STOP button. Investigate and correct before operating the machine further.

If you cannot easily locate the source of an unusual noise or vibration, feel free to contact our service department for help.

Blade Tension

Proper blade tension is essential to any cutting operation on the bandsaw. Any time you change blades or remove a blade, you must re-adjust the tension.

To adjust the tension:

1.Loosen the upper and lower guide blocks. Tighten them down and away from the blade BEFORE turning ON.

2.Lower the upper guide block assembly down to the table and tighten.

3.With moderate tension already on the blade, turn the bandsaw ON.

4.If you see the blade start to flutter, increase the tension until the blade stops fluttering, then tighten the tension handle an additional half turn.

If the blade does not flutter, decrease the tension until it begins to flutter, then tighten just to the point that it stops fluttering. Now tighten the tension handle an additional half turn.

5.Turn the bandsaw OFF and make the other adjustments in this section. Also, check the tracking and blade guides to make sure that they did not change after tensioning the blade.

If the blade does not cut properly, the tension may be incorrect. Re-adjust the tension.

After setting the tension, make a note of what the tension gauge reads. Use this to go back to your tension setting during later tensioning and reten- sioning with that particular blade.

Keep in mind that blades will last longer if you release the tension after every use. Also, new blades will often stretch with use. A tension that worked well when a blade was new may not work as well after the blade has been used.
