2.Clearance between the blade and the guide- blocks should be .004" (similar to the thick- ness of a dollar bill). For an easy gauge, fold a dollar bill in half and place each half on each side of the blade as in Figure 28.
3.Adjust the guide blocks and lock into position by tightening the thumbscrews. Remove the dollar.
Figure 29. Single dollar thickness on each side
of the blade.
The support bearings back-up the blade during the sawing operation. To adjust the upper sup- port bearing, loosen the shaft setscrew. The upper blade support bearing should be adjusted to within .016" (four thicknesses of a dollar bill) behind the blade as shown in Figure 29. Retighten the shaft setscrew.
LOWER BLADE GUIDE ASSEMBLIES
The lower blade guide assemblies should be adjusted to the same tolerances as the upper guide assemblies.
1.Adjust lower support bearing to within .016" from the rear of the blade.
2.Adjust lower
3.Adjust lower
4.Secure all adjustment knobs and screws.
5.Make sure the blade tracks true. Inspect for any blade deflection caused by incorrect positioning of the guide blocks. The support bearings should rotate only under load.
