HOW TO AdJUST THE POSITIVE STOPS
This machine has positive stops that will allow you to quickly and accurately position the blade at 90° and 45° to the
table. To check and adjust the positive stops:
1. Raise the blade to its fullest height.
2. Position a square (A) Fig. 40 against the blade and the table to check the angle.
3. If the blade is not 90° to the table, remove the lock screw located inside the hole (B) and slightly loosen the adjust-
ment screw located underneath the lock screw. Rotate the tilting handwheel until the blade is at the correct angle.
Tighten the adjustment screw until it bottoms. Replace the lock screw. Check the angle of tilt indicator on the hand-
wheel is pointing to "0". If not, adjust it.
4. Tilt the blade as far as it will go by turning the tilting handwheel counter-clockwise.
5. Position a square (A) Fig. 41 against the blade and the table to check the angle.
6. If the blade is not 45° to the table, remove the lock screw located inside the hole (C) and slightly loosen the adjust-
ment screw located underneath the lock screw. Rotate the tilting handwheel until the blade is 45° to the table. Tighten
the adjustment screw until it bottoms. Replace the lock screw.
