(3) How to set the memory switch
1) How to set the soft-start speed (Memory switch Nos. 1 to 5)
Number of revolution of the sewing machine from 1st stitch to 5th stitch can be set per stitch.
No. 1 : Number of revolution of 1st stitch
No. 2 : Number of revolution of 2nd stitch
No. 3 : Number of revolution of 3rd stitch
No. 4 : Number of revolution of 4th stitch
No. 5 : Number of revolution of 5th stitch
Caution : Number of revolution of the number of stitches in the rear can be set lower. However, the
sewing machine runs at the number of revolution which has been set and may not run
smoothly.
2) How to set the needle thread tension (Memory switch Nos. 6 to 9 and 65)
Setting of needle thread tension at the respective sections can be performed.
No. 6 : Setting of tension at the start of sewing (As many as the number of stitches set by data No. 26)
No. 7 : Setting of tension at the end of sewing (As many as the number of stitches set by data No. 24)
No. 8 : Setting of tension at the time of thread trimming (Tension set is kept for one second after
completion of sewing.)
No. 9 : Setting of tension at the time of basting
No. 65 : Setting of tension at the time of basting for sewing together
3) Individual tension setting of left/right parallel section and 1st/2nd bar-tacking section (Memory switch No. 39)
This switch is used when individually setting tension of all left/right parallel section and 1st/2nd bar-
tacking section.
0 :
Individual setting impossible (Common to left/right parallel section and 1st/2nd bar-tacking section)
1 : Individual setting possible.
Example) Set the memory switch No. 39 to “1 : Individual setting”.
Changeover of left parallel section and right parallel section can be performed every time
pressing the parallel section tension key on the panel.
Similarly, changeover of 1st bar-tacking section and 2nd bar-tacking section cab be
performed every time pressing the bar-tacking tension key.
Example) Left parallel section
Right parallel section
1st bar-tacking section
2nd bar-tacking section
* Normally, it is possible to select the data and to individually set the tension. However, when setting
tension using the tension key, the tension is common to each section. (Parallel section : data No.
17, bar-tacking section : data No. 19)
