Proper setting
When in the upper end position, the raised carrier roller must not come
into contact with the sewing foot.
After the carrier roller has been placed on the throat plate, the rocker
must still be deflecting by approx. 1 mm in the lower end position before
the stop of the lever reaches its end position.
Important
If using a steel carrier roller, you need to ensure that there is a still a light
gap in the lower end position. The steel carrier roller must NOT rest on
the throat plate.
