Information
The thread does not have to be wound onto the bobbin by hand.
7. Sew.
The hook thread is wound on for as long as the machine is
sewing. The winder lever (4) stops winding automatically as
soon as the bobbin is full. The winder (6) always stops such
that the cutter (5) is at the proper position.
8. Pull off the full bobbin.
9. Clamp the thread behind the cutter (5) and tear it off.
Information

4.7 Thread tension
Together with the hook thread tension, the needle thread tension
influences the final seam pattern.
The needle thread tension is defined by the pre-tensioner, the
main tensioner and the additional tensioner.
Proper setting
If the tension of needle thread and hook thread is identical, the
thread interlacing lies in the middle of the sewing material.
Set the needle thread tension so that the desired seam pattern is
achieved with the lowest possible te nsi o n.

4.7.1 Setting the needle thread tension
Fig. 13: Setting the needle thread tension
(4) - Main tensioner
(5) - Addi tional tensioner
Setting the pre-tensioner
When main tensioner and additional tensioner are open, a small
amount of residual tension of the needle thread is required.
This residual tension is generated by the pre-tensioner.
The pre-tensioner influences the length of the cut needle thread
end. The cut needle thread end is the initial thread for the next
seam. Reliable operation of the thread cutter can only be achieved
with a properly set pre-tensioner.
To set the pre-tensioner:
1. Turn the pre- tensioner (6) until the front side is flush with the
bolt.
• Set a shorter initial thread: turn counterclockwise
• Set a longer initial thread: turn clockwise
Setting the main tensioner
The main tensioner determines the normal tension during sewing.
Set the main tensioner as low as possible.
(6) - Pre-tensioner
Operating Instructions 670/680 - 00.0 - 01/2017 27
Operation
Important
The thread interlacing must be exactly in the middle of the sewing
material. With thin sewing material, excessive thread tension can
lead to undesired gathering and thread breaking.
To set the main tensioner:
1. Set the main tensioner (4) so that an even stitch pattern is
achieved.
• Increase the tension: turn clockwise
• Reduce the tension: turn counterclockwise
Setting the additional tensioner
The additional tensioner (5) is used to quickly adjust the needle
thread tension, e.g. for thickened seams.
The additional tensioner (5) can be switched off at the thickened
seam to loosen the seam. To tighten the seam, the additional
tensioner (5) is switched back on after the thickened seam.
To set the additional tensioner:
1. Set the additional tensioner (5) so that an even stitch pattern
is achieved.
• To increase the tension:
Turn adjusting wheel clockwise
• To reduce the tension:
Turn adjusting wheel counterclockwise
