The needle guide (5) should guide the needle during the sewing process in
order to avoid its excessive deflection by the sewing material. 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 / 120-140 Nm).
Proper setting
When the needle is at its lowest position, its distance to the needle guide
should be as small as possible, but the needle should not touch the guide.
If the distance is too narrow, the needle may break in the area of the
groove. If the distance is too wide, skipped stitches can occur on account
of the needle being deflected excessively by the sewing material.
To set the position of the needle guide:
1. Press the Lift/lower sewing head
The sewing head lowers.
