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 prematurely. This bandsaw is equipped with a
blade tension scale, which can be used as a reference for the ideal setting with various blade widths.
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 being cut will have an
effect on the blade tension.
Note: The tension indicator B at the rear of the up-
per wheel housing indicates the proper tension for
the various blade widths. Set the tension indicator to
correspond with the width of the blade in use.
