3.To adjust, loosen the locknut (B) Fig. 25, and turn the screw (C) until the head of the screw (C) contacts the casting (D) when blade is 90° degrees to the table. Tighten the locknut (B).

4.Loosen the bevel lock handle. Move the cutting arm all the way to the left bevel position and tighten the bevel lock handle.

5.Use a combination square (A) Fig. 26 to see if the blade is at 45° to the table.

6.To adjust, loosen the locknut (E) Fig. 27, and turn the screw (F) until it contacts the casting (G). Tighten the locknut (E).

7.Check to see that the bevel pointer (P) Fig. 28 is pointing to the 45° mark on the bevel scale (S) Fig. 26. To adjust the bevel pointer (P) Fig. 28, loosen the screw (H) and adjust pointer (P). Tighten the screw (H) securely.

8.These positive stops enable you to rapidly position the blade at the 90° and 45° bevel angle to the table.

ADJUSTING THE TENSION OF THE CUTTINGHEAD RETURN SPRING

WARNING: CUTTING HEAD MUST RETURN QUICKLY TO THE UP POSITION. DISCONNECT MACHINE FROM POWER SOURCE.

The tension of the cuttinghead return spring was adjusted at the factory so that the cuttinghead returns to the "up" position after cutting.

To adjust the spring tension, loosen the locknut (A) Fig. 29 and turn the screw (B) (clockwise to increase or counterclockwise to decrease the spring tension). After adjustment, tighten the locknut (A).

ADJUSTING SLIDING FIT BETWEEN CUTTINGHEAD ARM AND TRUNNION

After a long period of time, an adjustment of the sliding fit between the cuttinghead arm (B) Fig. 29A, and the trunnion (C) may be necessary. To adjust, turn the nut (D). This adjustment should not be so tight that it restricts the sliding movement of the cuttinghead arm (B) or so loose that it affects the accuracy of the saw cut.

ADJUSTING THE LOWER BLADE GUARD

WARNING: DISCONNECT THE MACHINE FROM POWER SOURCE.

This machine incorporates a blade guard (A) Fig. 29B to cover the rear section of the blade. After an extended period of use, the movable lower blade guard may not operate smoothly when the cuttinghead is lowered. This can be corrected by adjusting nut (B) until the lower blade guard moves freely.

WARNING: Overtightening the nut could impair guard movement.

NOTE: This unit has been designed with an articulating rear guard. Before contacting the workpiece, the rear guard will rotate upward to expose more of the blade as the cuttinghead is lowered.

WARNING: DO NOT REMOVE ANY OF THE BLADE GUARDS.

WARNING: Make sure that all guards are in place and functioning properly before operating the saw.

WARNING: Make sure that the fences are clear of the guard and blade before operating the saw.
