Blade Guide Support Bearing
The blade guide side bearings support and twist the
blade straight so the blade will enter the workpiece
perpendicular to the table surface (see Figure )(). The
blade guide support bearings prevent blade twist by
stopping the blade from being pushed back during a cut.
Both adjustments are critical for correct saw operation.
Note: Make sure the blade is tensioned and tracks
correctly before you adjust the blade guide bearings.
Refer to Blade Tension on the previous page and Blade
Tracking on Page)0 for detailed instructions.
To adjust the guide bearings, do these steps:
(% DISCONNECT BANDSAW FROM POWER!
)% Let the bandsaw headstock park in the full down
position.
*% Use a 12mm wrench to loosen the lower guide

+% Adjust the blade guide housing so the support
bearing rests against the rear of the blade, as
illustrated in =`^li\)(%
,% Tighten the adjustment hex bolt.
-% Use a 14mm wrench to loosen the outer side bearing
eccentric jam nuts of the upper guide bearing.
Note: The inner side bearing are not on eccentric
shafts and cannot be adjusted.
.% Use a 12mm wrench to rotate the side bearing
eccentrics until the bearings hold the blade
perpendicular to the table surface, and have a
bearing-to-blade clearance of 0.000"—0.001". The
bearings must not pinch the blade.
Note: To make sure the blade is perpendicular to the
table, use a standard machinist's square.
/% Tighten the jam nuts, loosen the lock knob, and slide
the blade guide close to the workpiece so the blade
is supported and will not twist during the cut (see
