Thread tension
Together with the hook thread tension, the needle thread tension
influences the final seam pattern. With thin sewing material,
excessive thread tension can lead to thread breakage.
Proper setting
The needle thread tension must be tighter than the hook thread
tension. To ensure the proper setting, the hook thread tensioner
is equipped with a spring made of thinner wire
Disturbance from incorrectly set thread tension
• Too tight: Crimping of the sewing material
• Too loose: Missing stitches
The thread tension is set at the
OP3000
control panel (
If 100 % thread tension is insufficient, the thread pre-tension can
be supplemented (
). To this end, the tensioner elements
of the thread pre-tensioner are set closer together. The tensioner
elements of the thread pre-tensioner are, otherwise, always open.
