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 a cut has been made. If it becomes necessary to adjust the spring tension:
Loosen the locknut (A) Fig. 27 and turn the screw (B) clockwise to increase, or counterclockwise to decrease the
spring tension. After adjustment, tighten the locknut (A).

After a long period of time, an adjustment of the sliding fit
between the cuttinghead arm (B) Fig. 27A, and the
trunnion (C) may be necessary. To adjust, tighten 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.
