SECTION 5: ADJUSTMENTS

Blade Adjustments

Blade tension and tracking are two of the most important factors affecting bandsaw perfor- mance. When the blade is properly tensioned and tracked, blade life will be extended, cuts will be straighter, and the bandsaw will run more smoothly. In order to optimize tension and track- ing, the two wheels must be co-planar (or in the same plane).

Follow the steps outlined here in the order pre- sented for best results: (A) adjust tension, (B) check co-planarity, (C) adjust co-planarity (D) check tracking, and (E) adjust tracking.

Tension

1.The power must be off with the saw unplugged. Lower the upper guide assembly all the way by loosening the guide post securing knob (#31) and lowering the assembly.

2.Press, with moderate pressure, on the face of the blade with your thumb. Figure 4.

3.The blade should flex no more than 1/2" with moderate pressure.

4.If it flexes too little or too much, turn the ten- sion adjustment knob (#2) to modify the ten- sion until it is correct.

If the tension seems correct, make the other adjustments to the saw and test run it. Re-adjust tension if the blade does not cut correctly.

Figure 4. Checking blade deflection.

Blades are extremely sharp. Use added care when making adjustments that require touching the blade with your fingers. Failure to do so could result in serious personal injury.

With the exception of those procedures which require test running the machine, DO NOT attempt adjustments without ensuring that the machine is turned off and discon- nected from its power source. Serious per- sonal injury may occur.
