Caution: Danger of injury!
Turn off the main switch.
Check and set the position of the feed dog only when the sewing
machine is switched off.
Rule and control

The feed dog must lie centric in the throat plate cutout.
In the feeding direction:
At the maximum stitch length, the minimum clearance of the feed
dog to the front and rear edges of the throat plate cutout must be
approx. 0.5 mm.
The clearance is required so that the feed dog does not hit against the
throat plate during sewing.

Turn the handwheel and check the position of the feed dog.
