旋梭和針板的間隙
出廠時， 旋梭 （1） 和針板 （2） 的間隙 （A）
的尺寸為 1.4-1.7mm。
●在更換旋梭（1）和針板（2）等對間隙
（A） 有影響的部件時， 請確認間隙 （A）
●要調整間隙（A），需要更換旋梭（1）
和旋梭底座（3）之間的軸向墊圈（4）
●軸向墊圈（4）有四種，請在測定現在
的軸向墊圈（4）的厚度之後，更換厚
度合適的軸向墊圈（4）

●更換旋梭（1）的時候，旋松固定螺釘
（5）[3 個 ]，此時，請不要取下軸向
墊圈（4）。
注意
將供油用的油氈（7）放在旋梭軸（6）的
底部。將旋梭（1）向下輕壓，用固定螺
釘（5）固定好，使旋梭（1）沒有浮動。
間隙過大的情況
●中旋梭可能離開針板（2）
間隙過小的情況
●線鬆緊不良不好
●可能發生剪線錯誤
●右面線可能被切短
Clearance between rotary hook and needle plate
The clearance (A) between the rotary hook (1) and the needle
plate (2) is 1.4-1.7 mm.
● Check clearance (A) each time parts such as the rotary hook (1)
and the needle plate (2) that affect clearance (A) are replaced
● To adjust clearance (A),replace the thrust ring (4) that is in
between the rotary hook (1) and the rotary hook base (3)
● Three types of thrust ring (4) are available.Measure the
thickness of the thrust ring (4) that is currently being used,and
replace it with a thrust ring (4) of the appropriate width

● When replacing the rotary hook (1),loosen the three set screws
(5). Be careful not to lose the thrust ring (4) at this time.
NOTE
There is a piece of felt (7) for lubrication at the base of the rotary hook
shaft (6). Gently press down on the rotary hook (1) when tightening
the set screws (5) so that the rotary hook (1) does not lift up.
If the clearance is too large
● The inner rotary hook may come out from the needle plate (2)
If the clearance is too small
● Poor thread tightening may occur
● Lower thread trimming errors may occur (models with thread
trimmer)
● The right upper thread may be cut too short (models with
thread trimmer)
