윗실  장력  조절 

1)

 

실  장력  1번  너트①를  시계방향(방향 

)으로  돌리

면  사절  후  바늘에  남은  실이  짧아집니다. 

2)

 

너트①를  반시계방향(방향 

)으로  돌리면  실  길이

가  길어집니다. 

3)

 

실  장력  2번  너트②를  시계방향(방향 

)으로  돌리

면  바늘실  장력이  증가합니다. 

4)

 

너트②를  반시계방향(방향 

)으로  돌리면  바늘실 

장력이  감소합니다. 

(2)

 

밑실  장력  조절 

1)

 

장력  조절  나사③를  시계방향(방향 

)으로  돌리면 

밑실  장력이  증가합니다. 

2)

 

나사③를  반시계방향(방향 

)으로  돌리면  밑실  장

력이  감소합니다

Adjusting theh needle thread tension 

1)

 

As  you  turn  thread  tension  No.1  nut①  clockwise  (in  direction 

),  the  thread  remaining  on  the  needle 

after thread trimming will be shorter. 

2)

 

As you turn nut①  counterclockwise (in direction 

), the thread length will be longer. 

3)

 

As  you  turn  thread  tension  No.2  nut②  clockwise  (in  direction

),  the  needle  thread  tension  will  be 

increased. 

4)

 

As you turn nut②  counterclockwise (in direction 

), the needle thread tension will be decreased. 

(2)

 

Adjusting the bobbin thread tension 

1)

 

As you turn tension adjust screw③  counterclockwise (in direction

), the bobbin thread tension will be 

increased. 

2)

 

As you turn screw③  counterclockwise (in direction 

), the bobbin thread tension will be decreased.

의  스트로크  변경 

1)

 

고정나사

를  풉니다. 

2)

 

사조자봉

을  시계방향(방향 

)으로  돌리면  실채기  스

프링의  스트로크가  증가합니다. 

3)

 

반시계방향(방향 

)으로  돌리면  스트로크가  감소합니다. 

(2)

 

실채기  스프링

의  압력  변경 

1)

 

고정나사

를  풀고  실  장력조절기(조)를  제거합니다. 

2)

 

고정나사

를  풉니다. 

3)

 

사조자봉

을  시계방향(방향 

)으로  돌리면  압력이  증가하게  됩니다. 

4)

 

반시계방향(방향 

)으로  돌리면  압력이  감소합니다. 

(1)

 

Changing the stroke of thread take-up spring① 

1)

 

Loosen set screw②. 

2)

 

As you turn tension post③  clockwise (in direction 

), the stroke of the thread take-up spring will 

be increased. 

3)

 

As you turn the knob counterclockwise (in direction 

), the stroke will be decreased. 

(2)

 

Changing the pressure of thread take-up spring① 

1)

 

Loosen set screw②, and remove thread tension(asm)⑤. 

2)

 

Lossen set screw④. 

3)

 

As you turn tension post③  clockwise (in direction 

), the pressure will be increased. 

4)

 

As you turn the post③  counterclockwise (in direction 

), the pressure will be decreased.
