After years of intensive use, a dimensional change of the shock
absorbing washer 5 may occur.
This is noticeable by the slower lowering of the sewing foot or an

It may signify that before the foot has reached the material to be sewn
completely it has already started to sew (risk of skipped stitches at the
seam beginning).
