4)调节结束后旋紧螺钉④,并将夹线器⑤(
组件)装入机器中再旋紧螺钉②。
3.挑线簧调整适当的判断依据
1)确认挑线簧①的张力调整好后,把面线向
B方向拉出,如果在挑线簧①达到最低位置之前
面线B处就被拉动,请减弱挑线簧①的张力。
4) Screw down screw ④ when adjustment is
over, fit tension disco ⑤(assembly) into the m
-achine, and screw down screw ②.
3.Judgment basis for adjustment adequacy of
take-up spring
1) Confirm that the tension of take-up sprin
-g ① is properly adjusted, draw out the needle
thread in direction B. If place B of needle threa
-d is drawn before take-up spring ① reaches it
-s lowest position, reduce the tension of take
-up spring ①.
注意:
1.为了防止缝纫机的意外启动,请关掉
电源之后再进行操作。
2.通常机器在出厂前,挑线簧均已调整妥
善,只是在缝纫特殊的缝料或特殊的缝
线时,才需要重新进行调整。
Caution:
1.To prevent the unexpected startup
of sewing machine, trim off the pow
-er supply before the operation is co
-nducted.
2.The take-up spring is already adju
-sted properly before the machine le
-aves the factory as a rule, and it req
-uires readjustment only for sewing
of special materials or usage of spe
-cial stitch threads.

1.面线张力的调节
1)若将夹线器中的调节螺母①朝顺时针方
向(即A方向)转动时,面线张力将增大;若朝逆
时针方向(即B方向)转动时,面线张力将减小。
2.底线张力的调节
1)若将夹线螺钉②朝顺时针方向(即C方向)转
动时,底线张力将增大;若朝逆时针方向(即D方
-1.Adjusting the tension of needle thread
1) The tension of needle thread is increase
