Bernina 8 SERIES V29.39.00 - Manual (Page 4)

2 SEwING UpdAtES
2.1 Thread tension for the underlay segments (buttonholes)
To eliminate possible thread loops, the thread tension for segments with short step stitches is inc-
reased from 2.0 to 3.0.
2.2 Manual threading
In some cases during manual threading, the thread swing support mechanism can be blocked.
This update avoids this issue without performing any mechanical readjustments.
