ADJUSTING THE BLADE GUIDES AND BACK-UP BEARING

NOTE: The upper and lower blade guides and back- up bearings support the band saw blade during cut- ting operations. The adjustment of the guides and bearings should be checked whenever a different blade is installed.

1.Adjust the back-up bearing first. Loosen the rear set screw using a 1/8" hex wrench. (This set screw is located on the right side of the upper slide for the upper bearing and on the right side of the frame just below the table for the lower bearing.)

2.Move the back-up bearing to within 1/32" of the blade. Tighten the rear set screw. Repeat on the other back-up bearing.

NOTE: The back-up bearing is to support the back edge of the blade while cutting. The blade should not contact the bearings when you stop cutting.
