CORD TRIM ADJUSTMENTS

Lower Thread Draw-off

The lower thread draw-off is used to supply enough lower thread into the buttonhole as it is forming the
stitch. This allows the thread to be trimmed and still have enough thread retained for the next buttonhole.
To adjust, perform the following step:
1. Actuator assembly B may need to be adjusted for correct tension release. The correct adjustment is
when actuator assembly B is resting against the race, and the lower tension disc is closed. When the
actuator is moved approximately 1/8" away from the race, the lower tension disc is opened. To adjust,
loosen screw C and move block D left or right as necessary.
2. The travel of the actuator assembly B must be correct. To adjust, loosen nut A and move stud up or
down as required. The standard setting for travel will have edges E and F parallel to each other once
actuator assembly B has completed its full travel. Once the correct travel has been obtained, re-tighten nut
A.
