Adjusting Blade Guide
Bearings
The blade guides provide side-to-side support to keep
the blade straight while cutting. The blade guides are
designed to be adjusted in two ways—forward/backward
and side-to-side.
To adjust the upper blade guides, do these steps:
1. Make sure the blade is tracking properly and that it
is correctly tensioned.
2. DISCONNECT BANDSAW FROM POWER!
3. Familiarize yourself with the upper blade guide con-
trols shown in Figure 27 & 28.
4. Loosen the lateral adjustment rod bolt, loosen the
support bearing adjustment shaft bolt, and adjust
the blade guides until the edges of the bearings are
1
/16" behind the blade gullets, as illustrated in Figure
29.
Note: The
1
⁄16" spacing is ideal, although with larger
blades it may not be possible. In such cases, adjust
the guide bearings as far forward to the blade gul-
lets as possible, and still maintain the proper sup-
port bearing spacing adjustment.

NOTICE
Make sure that the blade teeth will not contact the
guide bearings when the blade is against the rear
support bearing during the cut or the blade teeth
will be ruined.
5. Tighten the lateral adjustment rod bolt.
6. Loosen the bearing rotation adjustment bolts on
both sides of the blade.
7. Rotate the knurled knobs to position the bearings
0.004" away from the blade.
Note: 0.004" is approximately the thickness of a dol-
lar bill.
8. Tighten both of the the bearing rotation adjustment
bolts to lock the blade guide bearings in position.
