Blade Guide Bearings
The blade guide bearings are adjusted at the factory but due to shipping and storage may need adjustment. Use Figures 37 & 38 to guide you through the following steps.
To adjust the blade guide bearings, do these steps:
1.Before making adjustments, make sure the blade is tensioned and tracking correctly.
2.DISCONNECT THE BANDSAW FROM POWER!
3.Raise the bow high enough to give you room to work, then lock in place.
4.Remove both blade guards.
5.The back of the blade (A) in Figure 37 should make light contact with the backing bearing (C).
—If it does not, loosen the set screw (B) shown in Figure 37, and move the bearing (C) up or down until it lightly touches the back of the blade.
The blade guide roller bearings also need to be adjusted. The front bearing is mounted on an eccentric and can be easily adjusted to suit the blade thickness.
To adjust the blade guide roller bearings, do these steps:
1.Loosen the set screw in Figure 38 to allow the eccentric bushing to turn.
2.Turn the square nut on the eccentric shaft to adjust the distance of the guide bearing. The guide bear- ings and blade should make light contact or have a maximum clearance of 0.002".
3.Adjust the carbide blade guides so they make the same contact with the blade as the bearings.
4.Adjust the eccentric blade guide rollers bearing on the front arm the same way.
