Adjusting Support
Bearings
The support bearings are positioned behind the blade and support the back of the blade during cut- ting operations. Proper adjustment of the support bearings is an important part of making accurate cuts and also keeps the blade teeth from coming in contact with the guide blocks while cutting.
To adjust the support bearings:
1.Make sure that the blade is tracking properly and that it is correctly tensioned.
2.UNPLUG THE BANDSAW!
3.Familiarize yourself with the support bearing controls shown in Figure 22.
