ADJUSTING BLADE GUARD

1.The movable blade guard (A) Fig. 48, can be adjusted for proper movement as follows: Tighten nut (B) until the lower blade guard (A) moves smoothly as the cuttinghead is lowered.

2.As soon as the cuttinghead begins to lower, the lower blade guard (A) Fig. 49, should begin to move. If it does not, loosen screw (C) and rotate eccentric (D) so that the eccentric (D) is contacting the actuating arm (E) when the cuttinghead is in the top position. Then tighten screw (C).

ADJUSTING TENSION OF CUTTINGHEAD RETURN SPRING

The tension of the cuttinghead return spring has been adjusted at the factory in order that the cuttinghead returns to the up position after a cut has been made. If it ever becomes necessary to re-adjust the spring tension, proceed as follows:

1. Turn adjusting screw (A) Fig. 50, clockwise to increase or counterclockwise to decrease the spring tension.

ADJUSTING SLIDING FIT

BETWEEN UPPER ARM AND TRUNNION

When it becomes necessary to adjust the sliding fit proceed as follows: The fit between the upper arm (B) Fig. 50, and the trunnion (C) can be adjusted by tightening nut (D). Correct adjustment is when a good, snug sliding fit is obtained between these two parts. This adjustment should not be too tight that it restricts the sliding movement of the upper arm (B), or too loose that it affects the accuracy of the saw cut.
