point of each process, the needle goes up.

1) Free stitching and overlapped stitching
This stitching is not enabled even if this key is pressed.
2) Constant-dimension sewing:
Press this key.
This function is initiated by pressing the front part of pedal. Then, the
sewing machine automatically sews the number of stitches set for (E)
and stops.
3) Polygonal shape stitching:
Press this key.
The one-short switch is activated by depressing the front part of pedal.
Then, the sewing machine automatically performs sewing of the num-
ber of stitches set with the right-side value (G) and stops. When the
front part of pedal is depressed again, the sewing machine automati-
cally performs sewing of the next process and stops. The sewing ma-
chine repeats this procedure until it finishes sewing of the last process.
After the completion of last process, the sewing machine automatically
performs thread trimming.
Setting enable / disable of thread trimming:
As long as this switch is displayed on the screen, the sewing machine car-
ries out thread trimming.
If this switch is not displayed on the screen, the sewing machine will not
carry out thread trimming.
1) In the case this function is enabled, the sewing machine firstly operates
at a low speed when the motor starts by depressing the front part of
pedal. When the sewing machine has sewn the predetermined num-
ber of stitches, it runs at the normal sewing speed. When the motor
is re-started without thread trimming after the sewing machine has
stopped in the middle of sewing, the soft start function is not activated.
On the other hand, the soft start function is activated when the motor is
re-started after thread trimming.
2) The setting of sewing speed for the soft start function can be adjusted
with [007.S].
3) The setting of the number stitches for the soft start function can be
adjusted with [008.SLS].
