Jet Tools JWBS-14DX operating instructions Adjusting Lower Blade Guides and Blade Support Bearing

9.The blade support bearing should be adjusted so that the back edge of the blade overlaps the front face of the ball bearing approximately 1/8". To change position of the bearing, remove screw (H, Fig. 19), and bearing (G, Fig. 19), and back off knurled knob (F, Fig. 19) completely to remove the bearing shaft. Notice the bearing holder on the shaft is eccentric. Re-install the bearing shaft, the bearing, and the screw. Examine the overlap between the bearing face and the blade. Change the position of the bearing shaft until the overlap is approximately 1/8".
