The clearance between the point of the left needle
and the back side of the looper when the looper
moves to the right from the extreme left end of its
travel should be 0.3~0.6mm (The needle is pressed
to the back). The distance between the point of the
left needle and the center of the looper's eye on the
back side of the looper should be 3~3.5mm.
■
The amount of the looper front-to-back movement is
factory-set properly for needle count #11 (Nm75).
If you use needle counts Nm80~90, adjust the
amount as required.

Remove the inside cover.
Loosen nut B while holding screw A for the looper
