c) Distance between Looper and Needle (Fig.8) 

The  distance  between  the  Looper  poing  and  the  Needle
center should be 4mm when the Looper moves backward
at the farthest right position. Loosen the Nuts A and B,
and  turn  the  Joint  Rod  C  until  the  required  distance  is
obtained. After the adjustment, tighten the Nuts A and B
holding  the  Joint  Rod  C  and  keeping  the  above  proper
distance. 
 
Note: Make sure that the front face of the Ball Joint, left
D is correctly vertical, and is not in contact with the Oil
Drip Plate E finally. 
Please notice that the Nut A has left thread.

 

 

d) Clearance between Looper and Needle (Fig.8, 9) 

Adjust  the  Looper  so  that  the  Looper  point  will  lightly
touch the Needle concave as it passed behind the Needle
0-0.05mm. (Fig.9  ○

A ) 

Loosen  the  Screw  F  and  turn  the  Screw  G  as  required.
Turning  Screw  G  to  the  right  will  make  the  Looper  go
away  from  you,  and  turning  it  to  the  left  will  make  the
Looper  get  nearer  to  you.  After  the  adjustment,  tighten
the  Screw  F,  and  check  the  movement  of  the  Looper
again. (Fig.8)

 

 

e) Needle Height 

Adjust  the  height  of  the  Needle  Bar  so  that  the  Looper
point  is  0.4mm  above  the  Needle  hole  when  the  Looper
point reaches the left edge of the Needle. (Fig.7) 
To  adjust,  move  the  Needle  Bar  B  in  the  vertical
direction  after  loosening  the  Screw  A  of  the  Needle  Bar
Connection.  When  the  proper  height  is  obtained,  check
the position of the concave part of the Needle again, and
tighten the Screw A. (Fig8 of page 5)

 

 

f) Loop Guide Setting (Fig.9  ○

B

Mount the Loop Guide so that it will lightly contact the
front side of the Needle as the Looper moves forward.

 

5. Adjustment

/調整 

c) 

針とルーパーの距離(Fig.8) 

ルーパーが後退してもっと右側にきた時、ルーパーの先
端と針の中心までの距離は 4mm に調整してください。ル
ーパージョイントロッドのナット A、B を緩めてロッド C を回
して調整してください。 

 

針とルーパーの間隔が小さい場合は、ロッドを手前に回し
て、逆に大きい場合は反対に回してください。 

 

調整の後、ルーパージョイントロッドを動かさないようにし
て、ナット A、B を締め付けてください。 
 

注)ナット A は左ネジです。回す方向に注意してください。
注)ボールジョイント左 D は垂直に固定して、調整後も油受

け E に触っていないか、確認してください。

 

 

d) 針とルーパーの間隔 

ルーパーが前進して針の後ろを通過する時、針のえぐり
部とルーパーの間隔は 0〜0.05mm に調整してください。
(Fig.9  ○

A

ネジ F を緩めて、ストップネジ G を右に回すとルーパーは
奥の方へ、左に廻すと手前の方へ動きます。調整後ネジ
F を締めて、ルーパーの動きを確認してください。(Fig.8)

 
 
 
 

e) 

針の高さ 

ルーパーの先端が針の左側面にきた時、針穴の上面に
対して A 寸法が 0.4mm になるように、針棒の高さを調整し
てください。(Fig.7) 
 

 

調整は、針棒抱キのネジ A を緩め、針棒 B を上下させて
調節してください。(5 ページ、Fig.8)

 

 
 
 

f) ループガイド(Fig.9  ○

B

ループガイドはルーパーの動きにそって左に動く時、針
の前でかすかに接触するように取り付けてください。
