Setting the stitch length adjusting wheels
32 Service Instructions 667 - 00.0 - 04/2016
7.3 Setting the stitch length limit
If not all of the stitch lengths are available during sewing operation, a limit
can be placed on the maximum stitch length that can be set.
9 or 6 mm can be selected as the maximum stitch length. The appropriate
throat plate must be selected for the selected maximum stitch length.
The throat plate cut-out must be large enough to prevent the feed dog
from hitting the edges of the throat plate at the front and rear dead center.
Proper setting
Turn the upper stitch length adjusting wheel clockwise as far as it will go.
The upper stitch length adjusting wheel can only be turned up to the
set maximum stitch length.

Risk of damaging the feed dog due to incorrect throat plate size.
If the throat plate cut-out is too small, the feed dog may hit against
the edges.

maximum stitch length.
