ADJUSTING THE BLADE TENSION
A properly tensioned blade is critical to obtaining maximum performance from any bandsaw. A properly ten-
sioned blade will last longer and be much less likely to break prematurely.
If the blade tension is too loose you will notice that the blade will have a tendency to drift or slip off-line when
cutting and you will have more difficulty controlling your cuts. A blade that is tensioned too tightly will break pre-
maturely.
To tension the blade, proceed as follows:
1. Turn the blade tension knob A clockwise, raising
the upper wheel to tighten the blade. Turn the knob
counter-clockwise to lower the upper wheel, loos-
ening the blade.
Note: Changes in blade width and the type of material be-
ing cut will have an effect on the blade tension.
To make sure that the blade has been properly tensioned,
apply gentle pressure on the blade, it should not move
more than 1/4”. If the deflection is more than 1/4”, turn
the tension knob half turn, then check the blade deflection.
Repeat until the required tension.
