G0457 14" Industrial Bandsaw (Mfg. Since 5/11)
The blade guides consist of an upper and lower
set of ball bearings that provide side-to-side sup-
port to help 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 and lower blade guides:
1. Make sure that the blade is tracking properly
and that it is correctly tensioned.
2. DISCONNECT BANDSAW FROM POWER!
3. Familiarize yourself with the blade guide con-
trols shown in Figure 34.

4. Loosen the thumbscrew on the lateral adjust-
ment rod.
5. Rotate the lower knurled knob to position the
blade guides so the edges of the bearings are
1
/16" behind the blade gullets, as illustrated in
Figure 35.
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 for-
ward as possible to the blade gullets, and still
maintain the proper support bearing spacing
adjustment.

ment rod.
7. Loosen the cap screws.
8. With the 4mm hex wrench, rotate the center
portion of the blade guide bearings to laterally
position the bearings 0.004" away from the
blade.
Note: 0.004" is approximately the thickness
of a piece of paper.
9. Tighten the cap screw to lock the blade guide
bearings in position.
10. Repeat Steps 49 for the lower guides.
NOTICE
Make sure that the blade teeth will not con-
tact the guide bearings when the blade is
against the rear support bearing during the
cut or the blade teeth will be ruined.
NOTICE
Whenever changing a blade or adjusting ten-
sion and tracking, the upper and lower blade
support bearings and guide bearings must
be properly adjusted before cutting opera-
tions.
