" x 10" Metal-Cutting Bandsaw
The blade guide bearings come adjusted from the
factory and the need for adjustment should rarely
occur. Uneven blade wear and crooked cuts
may be the result of improper adjustment. Each
bearing assembly has an eccentric bushing that
allows the distance between the blade and bear-
ings to be adjusted. The bearings are secured in
place by a hex nut and a lock washer as shown
in
Figure 44.

Bearings
To adjust the blade guide bearings:
1. UNPLUG THE BANDSAW! 
2. Position the bandsaw in the vertical position
and close the feed rate ON/OFF valve.
3. Using a 12mm open-end wrench, loosen
the hex nut that secures the bearing to the
eccentric bushing.
4. Using a 7mm open-end wrench, adjust the
eccentric bushing position to achieve the
desired clearance. The bearing and blade
should make light contact or have a clear-
ance of 0.001"-0.002"
5. Tighten the nut to lock the bearing in posi-
tion.
6. Adjust the other eccentric blade guide bear-
ing in the same manner. The backing bear-
ing is not adjustable and will make contact
with the blade.
