(1)
Loosen the screw ③ of the spreader and the
screw ④ of the spring holder. (See Fig. 057.)
(2)
Adjust the spreader ① so that the clearance
between the left needle and the hook ② of the
spreader ① is 0.5 - 0.8 mm. (See Fig. 058.)
(3)
Make adjustment so that the distance from the
center of the left needle to the hook ② is
4.5 - 5.5 mm when the spreader ① is at the
extreme left. Then, tighten the screw ④. (See
Fig. 057 and 058.)
(4)
Make adjustment so that the distance from the
top surface of the stitch plate to the bottom
surface of the spreader ① is 11 - 12 mm.
Then, tighten the screw ③. (See Fig. 057 and

SUPPLEMENT
Match the height of the spreader ① according to the
needle distance within the adjustment range, so that
the top cover thread can pass behind the right needle
and be caught by the left needle.
