时针方向(即A方向)转动时，挑线簧的张力将增
大；反之朝逆时针方向(即
B
方向
)
转动时，挑线
簧的张力将减小。

挑线簧张力调整适当的判断方法：确认挑线
簧的张力调整好后，把面线向B方向拉出，如果
在挑线簧达到最低位置之前面线B处就被拉动，
请减弱挑线簧的张力。
Judgment basis for adjustment adequacy o
-f take-up spring:Confirm that the tension of t
-ake-up spring is properly adjusted, draw out
the needle thread in direction B. If place B of n
-eedle thread is drawn before take-up spring
reaches its lowest position, reduce the tensio
-n of take-up spring.
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。
通常，机器在出厂前,挑线簧均已调整
2.
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
