DISCONNECT MACHINE FROM POWER SOURCE.

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.
