Place a small combination square on the saw table beside
the blade.

position). Retighten the table lock
handle.
■
Using an adjustable wrench, adjust the zero stop set

ADJUSTING THRUST BEARINGS, BLADE
GUIDE SUPPORT, AND BLADE GUIDES
See Figures 13, 14, and 15.
The upper and lower blade guides and thrust bearings
support the band saw blade during cutting operations. The
adjustment of the guides and bearings should be checked
whenever a different blade is installed.
To Adjust Thrust Bearings:
The thrust bearings support the back edge of the blade during
cutting. The blade should not contact the thrust bearings when
you stop cutting. It is important that both upper and lower
thrust bearings be adjusted equally.
Note: The thrust bearing screw is the upper cap screw located
on the right side of the blade guide assembly. It is the lower
cap screw on the right side of the saw housing below the
saw table for the lower bearing.
See Figures 13 and 14.
