縫紉針距的更改
CHANGE OF STITCH LENGTH
縫紉針距的變化更改通過「送布量的變更」和
「送針量的變更」來實現。
1.
送布量的變更
送布量的變更通過交換上送布齒輪①和下送
布齒輪②來實現。
•
齒輪交換順序
⑴取下螺絲③（
2
個螺絲），並取下離合器盒
止動板④。
⑵鬆開螺絲⑤，取出上送布齒輪①。
⑶鬆開螺絲⑥，取出下送布齒輪②。（由於離
合器盒⑦而取不出下送布齒輪②的情況下，
直到離合器盒⑦的壓痕處到達下送布齒輪②
的上部為止，用手轉動縫紉機皮帶輪一邊拔
掉下送布齒輪②。）
⑷將與變更的縫紉針距長度對應的上送布齒輪
①，與離合器盒⑦對準後，一邊轉緊螺絲⑤
固定
⑸用螺絲③安裝離合器盒止動板④。
⑹壓腳放下的狀態下，將與變更的針距長度相
對應的下送布齒輪 ②，與上送布齒輪的齒距
相吻合，並用螺絲⑥固定。
Stitch length shall be changed by both
change of feeding amount of cloth and
change of needle distance.
1.Change of feeding amount of cloth
Feeding amount of cloth is changed by
replacing upper feeding gear
①
and lower
feeding gear.
•Sequence of replacing gear
⑴
Take off screws
③（
two screws
）
, and
take clutch case stopper
④
out.
⑵
Loosen screw
⑤
, and take off upper
feeding gear
①
.
⑶

⑦
by
turning Sewing Machine Pulley by hand till
it comes over lower feeding gear
②
, and
then take lower feeding gear
②
out.
）
⑷
Fix screw
⑤
as pressing upper feeding
gear
①
which correspond to the desired
stitch length against clutch case
⑦
.
⑸
Use screw
③
to install clutch case stopper
④
.
⑹
Lower the Presser all the way down,
and then fix lower feeding gear
②
of the
desired stitch length with screw
⑥
as
engaging it with upper feeding gear.
