Overriding automatic tension settings
Q. I don't know if this is a machine problem or a thread problem but
thought I would start here. I have the Bernina 830 and am piecing with
Masterpiece Thread. My top thread keeps breaking! My frustration level
is going up fast. Could it be because the thread is coming off the top
of the spool instead of the side? I put in a new needle but that hasn't
helped.
Thanks for any input you might have.
A. This is an occasional problem with Bernina's automatic tension
setting (it's too tight). Override the setting and reduce the top
tension to the 1.5 to 2.0 range. Make sure the spool is positioned
vertically on the upright pin so the thread unwinds straight from the
side and not over the end.
This should fix it.
