15) UPPER LOOPER ADJUSTMENT
1) When the upper looper is farthest from the left, adjust the
setting distance (b) between the end of the lower looper and
the center-line of the overlock needle depending on the
model. (Table 3)
(In case of 512 stitch, the distance (a) is between the center of
the looper eye and the center-line of the overlock needle.)
After this adjustment, tighten the screw② temporarily. When
the end of the upper looper is across the backside of the lower
looper, set the distance (c) about 0.5mm and the distance (d)
about 0.2mm. Then tighten the screw②.
2) When the upper looper is farthest from the left, adjust the
mentioned setting distance(b) between the end of the lower
looper and the center-line of the overlock needle then tighten
the screw②.
