Do not make adjustments while the band- saw is running. Ensure that the switch is off, power is disconnected, and moving parts have stopped before making adjustments. Check adjustments while power is still dis- connected by manually turning the bandsaw wheel by hand.

The controls for the blade guide are shown in Figure 14. The blade guide should always be positioned so there is minimal space between the guide and the top of the workpiece.

H. This knob locks the upper blade guide assembly in position. The upper guide should be adjusted to within 1⁄4" of the work- piece for optimum blade support. Do not operate bandsaw without locking the guide post knob.

I.These spring-loaded bolts apply pressure against the U-clamp to prevent the guide post from dropping when the upper blade guide knob is loosened.

Blade Tension

Proper blade tension is important for optimum bandsaw performance. See Figure 13 for band- saw tension controls. To increase blade tension, turn the blade tension knob clockwise. To reduce blade tension, turn the blade tension knob counter-clockwise.

Since a variety of blades will work well with this saw, final blade tension ultimately depends on the type and size of blade you use. Thin blades require less tension than wide blades. Too much tension will result in blade breakage.

A properly tensioned blade will track the cutting line accurately and the cut will be smoother.

Proper blade tension can best be achieved by determining the amount of blade deflection:

1.Ensure that the power is off and the saw is unplugged. Raise the upper guide assem- bly all the way and lock in place.

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

3.Turn the tensioning knob to adjust the amount of tension. The blade should deflect about 1/4".

If the tension seems correct, make all of the other adjustments to the saw and test run it. If the blade is not cutting properly, the tension may be incor- rect and readjustment may be needed.

Remember to reduce the blade tension when the bandsaw is not in use, this will help prevent pre- mature breakage of the blade and deformation of the rubber tires.
