ADJUSTING UPPER BLADE GUIDE ASSEMBLY
DISCONNECT MACHINE FROM POWER SOURCE.
The upper blade guide assembly (A) Fig. 24, should always be set as close as possible to the top surface of the material being cut by loosening lock knob (B) and moving the guide assembly (A) to the desired position.
ADJUSTING UPPER BLADE GUIDES AND BLADE SUPPORT BEARING
DISCONNECT MACHINE FROM POWER SOURCE.
The upper blade guides and blade support bearings are adjusted only after the blade is tensioned and tracking properly. To adjust proceed as follows:
1.The upper blade guides (A) Fig. 24, are held in place by means of the set screws (C) Fig. 24. The upper blade guide guard (D) Fig. 24 is held in place by bolts (E) and set screw (F) Fig. 24. Loosen the set screws (C) to remove the guides for maintenance.
2.The complete upper guide block assembly bracket
(A) Fig. 25, can be moved in or out by loosening set screw (B) Fig. 25. The guides (C) Fig. 25, should then be adjusted so that the front edge of the guide roller bear- ings are just behind the “gullets” of the saw teeth (D) Fig.
25.Be careful not to pinch the blade.
3.Both upper roller bearing assemblies (A) Fig. 26, can be adjusted by loosening the socket head cap screw (B) Fig. 26. Slide both bearing assembly guides (C) Fig. 26, sideways so the roller bearing outer surface is a couple of thousandths of an inch (about the thickness of a piece of paper) away from the blade. Tighten securely. Be care- ful not to pinch the blade.
4.The rear upper blade support bearing (D) Fig. 26, should also be adjusted so it is a couple of thousandths away from the back edge of the blade. The upper blade support bearing, prevents the blade from being pushed too far to the rear which could damage the set in the saw teeth.
