The needle guide 5 should guide the needle during the sewing process
in order to avoid its excessive deflection by the fabric. Otherwise,
skipped stitches can occur.
The distance between the hook and the needle must be checked after
inserting a needle that belongs to a different size group (80-110 Nm or.
120-140 Nm)
Caution: Danger of bodily injuries !
The machine must be in the position "Safe motor stop "
Rule and control
When the needle is in its lowest position, its distance to the needle
guide should be as small as possible, but it should not touch the guide.
If the distance is too narrow, the needle may brake in the furrow area..
But if the distance is too wide, skipped stitches can occur, because the
needle would be deflected by the fabric excessively.
