M1113 18" Wood/Metal Bandsaw

Blade Tensioning

A properly tensioned blade is essential for making accu- rate cuts and is a prerequisite for making many bandsaw adjustments. The blade tension is adjusted by rotating the blade tension lever.

To tension the bandsaw blade:

1.Make sure you have performed the Test Run instruc- tions on the previous page and you are certain that the blade is tracking properly.

2.With the blade tension lever in the down (engaged) position, adjust the blade tension until the indicator on the blade tension scale (Figure 23) matches the size of blade installed on the bandsaw.

Note: Because each blade is different and all blades stretch, this scale is only an approximation. Always measure blades from the tip of the tooth to the back of the blade.

3.Turn the bandsaw ON.

4.Release the tension one quarter of a turn at a time. When the bandsaw blade starts to flutter, stop decreasing the tension.

5.Now, slowly increase the tension until the blade stops fluttering, then tighten the tension one more quarter of a turn.

6.Turn the bandsaw OFF and read the tension gauge. Use the reading as a guide when tensioning that blade in the future.

Note: Do not rely on this measurement for long periods of time because the blade will stretch with use, making the tension gauge slightly inaccurate.

NOTICE

To reduce blade stretching, remove the tension from the blade when not in use.

NOTICE

After blade tension and tracking are set correctly, properly adjust the upper/ lower support bearings and guide-block assemblies into position before operat- ing machine.
