• 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.

in. behind the gullet of the blade, Tighten the

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.
