Adjusting the looper thread quantity
WARNING
Risk of injury from moving parts.
Switch off the sewing machine before adjusting
the thread take-up.
The looper thread take-up adjusts the looper thread quantity to the
relevant set stitch length so that the stitch pull is optimal for every
length and also for stitch condensing.
The looper 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.
