(1) When with thread clamp (motion), use the sewing machine after adjusting the needle thread length
at the start of sewing to 40 to 50 mm. When the needle thread length is too long, the needle thread
end held with the needle thread clamp may be rolled in the seams.

3)
When needle thread is excessively long at the time of using the thick thread, the end of nee-
dle thread held with the needle thread clamp is rolled in the seams, and slip of position of
material may occur or needle breakage may be caused.
(2) When the thread clamp is used, and bobbin thread at the sewing start appears on the right side of
material, reduce thread tension at the sewing start (2 to 3 stitches) and bobbin thread becomes less
conspicuous.
[Example of setting]
Tension of 1 to 2 stitches at the sewing start is "20" when sewing tension setting is "35".
* For setting of tension at the start of sewing, see of
