The guide bearings on either side of the blade ensure that it is not pushed too far laterally. Perform steps
1.Loosen the setscrews (#33) securing the guide bearing shafts (#38).
2.Turn the knurled ends of the bearing shafts. Adjust so that the bearings are about 0.004" (about the thickness of a piece of paper) from the sides of the blade. Figure 10. The bearings should also be as near to the same height as possible.

Use extreme care when making adjust- ments that require contact between the bandsaw blade and your hand.
