4.  이송타이밍  조정  /  Adjusting  the  feed  timing

3.  가마와 가마고정의 간격조정  / Adjusting the rotary  hook  holder  poaition

     ★ 내가마①와  가마고정②의 간격은  약0.7~0.9mm가  되도록 

         죔나사③을  풀고, 가마고정②를  앞  뒤 움직여서  정해 

         주십시오.

     ★ Loosen  the screw ③.   Move the  rotary  hook  holder

         ②  forward or  backward  so that  the gap  between  the

         rotary  hook  ① and the  rotary hook holder  ② is 

         approx  0.7~0.9mm.

조    정  /  ADJUSTMENT

 

1.  미싱풀리①를 앞쪽으로  돌려 톱니②가  상승해서 톱니끝이  침판③의 상면과  일치했을 때  바늘의 끝이  아래

     와 같이  되어 있는지를  확인해주십시오. 

   

․ 

중후물용  : 톱니의  상면과 침판의  상면과 바늘의  선단이 일치합니다.

   

․ 

후물용  : 톱니의  상면과 침판의  상면이 일치하고,  바늘의 선단과  침판의 상면은  5mm의  간격이 있습니다.

2.  이송타이밍이 다를때는  상하편심륜④의 고정나사⑤와  수평편심륜⑥의 고정나사⑦을  풀고 조정합니다.

     톱니가 빨리  내려갈때는 상하편심륜④과  수평편심륜⑥을 미싱의  회전방향과 반대방향에,  또 톱니가 

     늦을때는 미싱의  회전방향으로 조금  돌립니다.

3.  올바른 타이밍에  맞춰 고정나사⑤와  고정나사⑦를 확실히  체결해주십시오.

1.  Turn  the machine pulley①  toward  the front of the  machine  until  the feed dog② ascends and the

     tips of the  feed  dog②  align with the  upper  surface of the  needle plate③. At this  time,  check that  the

     needle tip  is as  indicated  below.

 

․ 

For  thin  materials  : The needle  tip  is aligned  with tips  of  the feed  dog② and  the upper  surface of the

                                 needle  plate③.

 

․ 

For  thick materials :  There  is a  5mm  gap between the  needle tip and the  upper surface  of  the needle  plate③.

2.  To  adjust  the timing, loosen  the screw⑤ of the  feed  lifting eccentric  wheel④ and the  screw⑦  of  the level  feed

     eccentric  wheel⑥. If the  feed  dog  descends below the  needle plate too  soon,  turn the  feed lifting  eccentric

     wheel④ and the  level feed eccentric  wheel⑥ opposite to  its normal rotation.   If  the feed  dog is  too late, 

     turn the  wheel slightly  forward.

3.  Tighten the  screws  ⑤ and ⑦.
