(B) Timing of the upperlooper in relation to the lowerlooper
1. Loosen the upperlooper screw.
2. Adjust the upperlooper not to bend the lowerlooper when the upperlooper travels nearest to the
lowerlooper.
NOTE: (a) When fastening the screw after adjustment, press the upperlooper slightly in order not to change
the corrected position.
(b) In case of bad timing, the upperlooper and the lowerlooper cross each other and do not work
correctly which will cause skipped stitches and loose tension.
(C) Setting the upperlooper lever to match the type of sewing selected
1. For two-thread sewing, lower the lever on top of the upperlooper as shown in the illustration.
(1) The lever should fit securely into the groove on top of the upperlooper after it has been moved
(lowered).
2. The lever should be returned to its original position after sewing is completed.
