① The presser foot pressure should be as weak as possible,
but strong enough so that the material does not slip. (Refer
to
“
Adjusting screw height
”
in the table below as a guide to
adjustment).
1.Loosen the adjusting nut (1).
2.Turn the presser adjusting screw (2) to adjust the presser foot
pressure.
3.Tighten the adjusting nut (1).
②
Adjusting the trailing length after thread trimming
At the time of thread trimmind, the thread tension is loosened
and tension is applied by the pretension (1) only. The normal
trailing length for the upper thread is 35 mm.
If the tension of the pretension (1) is increased, the lengths of
the threads trailing from the needle tips will be reduced; If the
tension is reduced, the lengths will be increased. Adjust by
turning the pretension (1). Turn clockwise (1), and the length of
the residual length of the surface is shortened, otherwise, the
length becomes longer.
①應盡可能減小壓腳壓力，但需有足夠壓
力使布料不致滑動。（以下表的“壓
腳調節螺栓高度”為大致標准進行調
節）。
1. 鬆開調節螺母（ 1 ）。
2. 轉動壓腳調節螺栓（ 2 ）以調節壓腳
壓力。
3.
擰緊調節螺母（
1
）。
②剪線後面線殘留長度的調節
剪線時，線張力鬆弛，可以用夾線器
（
1 ）施加張力，面線的正常殘餘量為
35mm 。
如果增加夾線器（
1
）的張力，切線後
面線殘留長度將會減少；減小張力，面
線殘留長度將轉會動增夾加線器（
1 ）
進行調節，順時針轉動（ 1 ） , 面線殘留
長度變短；逆時針轉動（
1
）
,
面線殘留
長度變長。
