5. 線張力
⑴挑線彈簧（直鎖眼縫）
1) 挑線彈簧①的挑線量為 8 ～ 10mm，始動
強度 0.06 ～ 0.1N 左右較為適當。
2) 改變挑線彈簧的動作量時，請轉鬆螺絲
②，把細螺絲刀插到線張力桿③ 的缺口部
轉動調節。
3) 改變挑線彈簧的強度時，請在螺絲②鎖緊
的狀態下，把細螺絲刀插到線張力桿③的
缺口部轉動調節。向右轉動之後，挑線彈
簧的強度變強，向左轉動之後，強度變弱。
⑵挑線桿挑線量的調整
挑線桿的挑線量，根據布料的厚度進行調
節。
1) 縫製厚料時，鬆開導線器①的固定螺絲
②，向左移動導線器。
2) 縫製薄料時，把導線器①向右移動。挑線

5. Thread tension
(1) Thread take-up spring (purl stitch)
1) The thread take-up amount of thread
take-up spring ① is 8 to 10 mm, and
the appropriate pressure at the start is
approximately 0.06 to 0.1N.
2) To change the stroke of the thread take-
up spring, loosen screw ② , insert a
thin screwdriver into the slot of thread
tension post ③ , and turn it.
3) To change the pressure of the thread
take-up spring, insert a thin screwdriver
into the slot of thread tension post ③
while screw ② is tightened, and turn
it. Turning it clockwise will increase
the pressure of the thread take-up
spring.Turning it counterclockwise will
decrease the pressure.

take-up lever should be adjusted in
accordance with the thickness of the
sewing products so as to obtain well-
tightened stitches.
1)For heavy-weight materials, loosen
setscrew ② in thread guide ① , and
