Setting the hook thread quantity
The hook thread quantity released is determined by the position
of the hook thread take-up. The hook thread take-up adapts the
hook thread quantity to each set stitch length to allow for the best
possible stitch pull at any length and even with stitch condensing
enabled.
The hook thread take-up can be adjusted continuously on a scale
from 0 to 5. The larger the value, the greater the released thread
quantity and the more elastic the seam.
Proper setting
The proper setting is dependent on the stitch length and the seam
type.
You need to ensure, especially when applying extreme settings,
that the needle reliably plunges into the thread triangle:
• Elastic seam (3) with a very short stitch length = scale 5
• Tighter seam (1) with a significantly increased stitch length =
scale 0
