7.2 Adjusting 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.
12, 9, or 6 mm can be selected as the maximum stitch length. The appro-
priate throat plate must be selected for the selected maximum stitch
length. The throat plate cutout 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 stitch length adjusting wheel clockwise as far as it will go.
The stitch length adjusting wheel can only be turned up to the set
maximum stitch length.
NOTICE
Property damage may occur!
Risk of damaging the feed dog due to incorrect throat plate size.
Ensure that an appropriate throat plate is used for the selected
maximum stitch length.
