ADJUSTING BLADE GUIDE BEARINGS
Disconnect machine from power source.
1. The blade guide bearings (A) and (B) Fig. 20 should
be adjusted so they just touch the sides of the
blade (C) after the blade is tracking properly and the
blade support bearing has been adjusted. To adjust,
proceed as follows:
2. Remove the cover plate that is attached to the face
of the right guide bracket (D) Fig. 20.
3. The inside guide bearing (A) Fig. 20, is mounted to
a fixed shaft and cannot be adjusted. The outside
guide bearing (B) is mounted on an eccentric shaft
and should be adjusted so that the sides of the

(B). To adjust, loosen nut (E) and turn adjusting nut
(F) until proper adjustment is made. Then tighten
nut (E).
4. Adjust the other blade guide bearings in the same
manner.
