The take-up lever 1 ensures that the thread quantity is automatically
matched to the stitch length set.
Stitch drawing and stitch formation are therefore always perfect for
every stitch length, even with stitch condensation. The drawn-in thread
quantities can be changed depending on the type of seam.
Without a change in the thread tensions, the following occurs:
a) tight
b) normal
c) highly elastic (ballon stitch) seams.

Adjust the thread take-up lever
Direction 0 tighter seam
Direction 5 elastic seam.
Important!
1) By extreme Settings, e.g. a shortest possible stitch length and a
greatest possible thread quantity (elastic seam) care is to be taken
that a sure penetration of the needle into the thread triangle is still
possible. With a too large hook thread quantity missing stitches can
occur.
2) If with the setting values described under 1) the stitch length is
greatly increased, then this requires that the thread guide be set back
in the direction of 0. Otherwise a jumping off of the hook thread from
the thread take-up disk can occur.
