Blade Tension

The only way to accurately tension the blade on this machine is with a blade tensioner such as the Model H5408 on page 33. This method is for rough blade tensioning only.

5.Turn the bandsaw ON.

­—If the blade flutters, increase the tension until the fluttering stops, then increase the tension an additional quarter turn.

—If the blade does not flutter, decrease the tension until it begins to flutter, then re-ten- sion until it stops fluttering, then increase the tension an additional quarter turn.

6.Turn the resaw OFF and disconnect the resaw from the power source!

7.Replace the blade guide upper plate and set the guides as explained in Adjusting the Blade Guides on page 42.

If the blade does not cut properly, the tension may be incorrect. Re-adjust the tension. A tension that worked well on a new blade may not work on an old blade because blades stretch with use. Bandsaw blades will last longer and stretch less if they are de-tensioned after each use.

NOTICE

These instruction are for rough tensioning only. The only way to accurately tension the blade is with a blade tensioner. Premature blade breakage is often caused by improper blade tensioning.
