In the above-mentioned position, there is a very slight clearance between the
point of looper and needle. It is necessary that the needle pass 0.1-0.2mm to the
needle guard, but widiout actually rubbing against it. (see fig 8). Notice: The
clearance between needle and needle guard should be the same when the needle is
swinging right and left.
B. The relative position of needle, looper and spreader.
Turn the needle down from the highest position until needle point is in line with
the bottom of spreader. Then the spreader should be in a state of relative rest while
the needle will continue its downward stroke until the lowest position. The needle
will move upward from the lowest position to such a position where the spreader is
beginning to swing (but still in a state of rest). In such a position, the clearance
from the point of looper to fork of spreader should be 0-0.85mm.Loosen set screw'
of spreader to adjust.(see fig 8a).
