The overfeed foot is adjusted at the factory so that light and
medium-weight material is laid on the feed dog in parallel.
The lay (inclination) can be altered to suit the material.
Caution: danger of injury
Turn off the main switch.
The inclination of the overfeed foot may only be adjusted with the
sewing machine switched off.

checked and corrected if necessary.
