Move the thrust bearing to within 1/64 in. of the blade. Tighten the thrust bearing screw securely. Repeat this procedure on the lower thrust bearing, located below the table.

Note: The thrust bearing is to support the back edge of the blade while cutting. The blade should not contact the bearings when you stop cutting. It is important that both thrust bearings be adjusted equally.

TO Adjust Blade Guide Support

Next, adjust the position of the blade guide support. Loosen the bottom screw on the right side of the blade assembly using the hex key.

Slide the blade guide support on the shaft until the front edge of the blade guides are about 1/64 in. behind the gullet of the blade, Tighten the screw securely. Repeat this procedure for the lower blade guide support.

To Adjust Blade Guides

The blade guides help keep the blade from twisting and binding. Letting the blade teeth hit the blade guides while using the band saw will ruin the blade. The set of teeth and the sharpened edge of teeth will be damaged by hitting the blade guides, Proper adjustment of the upper and lower blade guides will prevent this from happening.

Loosen the two blade guide screws that lock the upper blade guides. Press the two guides evenly near the sides of the blade leaving about 0.004 in. from the blade. (0.004 is the thickness of a dollar bill.) Do not pinch the blade. Make sure one guide is not further away from the blade than the other. Release the guides and tighten both screws securely.

Repeat this procedure on the lower blade guides located under the table. See Figure 21.
