7. Selection and confirmation of the sewing patterns
1) The patterns for eyelet buttonhole bartacking are from No. 11 to No. 13.
2) When the material closing operation is performed, the maximum sewing size is 3x7mm. Set the most
appropriate size using the enlargement/reduction function. As for the way of operation for setting, checking
or changing the sewing pattern, refer to the item “Operation of the sewing machine (basic)” described in
the instruction material for the LK-1900A.
After setting, check the needle entry point whether or not the needle interferes with the work
clamp foot.
Sewing size is the dimension when
the enlargement rate is 100%.

WARNING :
In case of using an exclusive work clamp foot, make sure of the shape of the sewing pattern. If the
sewing pattern extends outside the work clamp foot, the needle interferes with the work clamp foot
during sewing, resulting in the danger of the needle breakage or the like.
