Difficulties in feeding the sewing material
(stitch lengths vary from settings)
Possible reasons:
- Feed dog is incorrectly adjusted; need to be set lower or higher
- Feed dog gearing is not suitable
- Different presser foot pressure left/right
- Lift-off of presser foot is blocked
- Blockage of sewing material in stitch plate, especially for cross-seams
- The loop remains stuck at the feed dog, for instance.
- Stitch length accidentally altered
- Spring-load plunger blocks at the cross-seam area
- Correct tension on the lower transport belts
Solutions:
- Check the height of feed dog and the stitch length and, if necessary,
replace the feed dog.
- Correctly adjust the pressure of the presser foot
- Check the lower side of the stitch plate and feeding/sewing parts for signs
of damage and, if necessary, replace or polish them
