blade selection

Proper tension is essential to avoid vibration, 

twist, or`slippage on the wheels. A correctly 

tensioned blade provides long life, straight cuts, 

and efficient cutting.

The three major signs of incorrect tension are: 

1) The blade stalls in the cut and slips on the 

wheels, 2) the blade frequently breaks, and 3) the 

cuts are not straight.

1.  Make sure the blade is tracking properly.

2.   DISCONNECT BANDSAW FROM POWER!

3.  Loosen and slide the blade guide as far out 

as it will go, then tighten it down again.

4.  Turn the tension knob in Figure 32 

clockwise to tighten the blade or clockwise to 

loosen it.

5.  Using moderate finger pressure, push 

against the side of the blade. If it flexes more 

than

", tighten the tension knob further, 

then repeat this step.

Many conditions may cause a bandsaw blade to 

break. Some of these conditions are unavoidable 

and are the natural result of the stresses placed 

on the bandsaw; other causes of blade breakage 

are avoidable. 

•  Faulty alignment or adjustment of the blade 

guides.

•  Forcing or twisting a wide blade around a 

tight radius.

•  Feeding the workpiece too fast.

•  Dull or damaged teeth.

•  Over-tensioned blade.

•  Top blade guide assembly set too high 

above the workpiece. Adjust the top blade 

guide assembly so that there is less than

between the bottom of the assembly and the 

workpiece. Understand that with smaller 

workpieces, this may not be possible. In 

these cases, simply adjust the blade guide as 

far down as possible.

•  Using a blade with a lumpy or improperly 

finished braze or weld.

•  Continuously running the bandsaw when not 

in use.

•  Leaving the blade tensioned when not in use.

•  Using the wrong blade pitch (TPI) for the 

workpiece thickness. The general rule of 

thumb is to have no fewer than three teeth 

in contact with the workpiece during cutting 

operations.
