4-6. Thread nipper device
This is used to stop the thread from pulling out at the sewing start, and at times when skipped stitches might easily occur.
The thread nipper device operates when memory switch no. 500 is set to "ON". However, some limitations apply. Refer to
"6-3. List of memory switches" for details.
* The default setting for this memory switch is "OFF".
[Notes on use]
1. When using the thread nipper device, turn the tension
nut (1) (sub-tension) to adjust the upper thread trailing
length to 35 - 38 mm.
* Adjust the upper thread trailing length to less than 40
mm after replacing the upper thread also.
2. If the upper thread trailing length is 40 mm or more, or if
the upper thread tension is weak and the upper thread
does not form a good seam at the first stitch, the end of
the thread that is being held by the thread nipper may
become wound around the seam.
Furthermore, if using thick thread that is #30 or higher or
if the thread trailing length is too long, an error [E691]
may occur.
In any of these cases, use scissors to cut the thread
without pulling it up too hard.
