Guide Bearing Adjustment
Referring to Figure 12:
Guide bearings are located on either side of the saw
blade and provide stability for the blade when the
saw is in operation. These bearings rotate on an
eccentric shaft so the distance from the blade can be
adjusted for optimal performance.
Guide bearings are initially adjusted at the factory
and should rarely require adjustment.
It is always better to try a new blade when cutting
performance is poor. If performance remains poor
after changing the blade, check the blade guides for
proper guide bearing spacing. For most efficient
operation and maximum accuracy, clearance
between the blade and the guide bearings should be
0.001-inch. The bearings will still turn freely with this
clearance. If the clearance is incorrect, the blade may
track off the drive wheel.
Disconnect the bandsaw saw
from its electrical power source.
If required, adjust guide bearings on one assembly
then the other as follows:
1. Using a 14mm wrench loosen two lock nuts (A)
that secure the eccentric bushings (B) while
maintaining the positions of the eccentric
bushings with a 6mm wrench.
2. Position the bearings (B) by adjusting the
bushings (C) with the 6mm wrench. Set the
clearance between the bearings (B) and blade
(D) at approximately 0.001 inch.
Note: Only the bearing towards the front is
mounted on an eccentric bushing. Make adjust-
ments on this bearing.
When properly adjusted, the blade should be in a
vertical position between the bearings as shown
in Figure 13.
3. While maintaining the new position of the
bushings with the 6mm wrench, secure the
settings by tightening the
lock nuts (A).
