The clearance between the point of the 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 0.1~0.2mm (The needle is pressed to the
back).
The amount of the looper front-to-back movement is
factory-set properly for needle count #21 (Nm130).
If you use needle counts Nm80~90, adjust the
amount as required.
