Input value on the

Presser foot pressure

panel
100 Approx. 15N (1.5 kg)
1. Be sure to input a positive value on the operation panel in the case the micro-lifter function is not
used. If not, the presser foot is slightly raised and the feed dog is unable to provide a sufficient
efficiency of feed.
2. In the case of using the micro-lifter function, the efficiency of feed is likely to be insufficient. To
achieve the sufficient efficiency of feed, reduce the sewing speed or help feed the material by hand.
3. In the case the set value on the operation panel is a negative value, the presser foot will go up
slightly during sewing.
4. In the case of slightly lifting the presser foot during sewing, the efficiency of feed is likely to be
inadequate. To compensate the reduced efficiency of feed, lower the sewing speed or support the
material feed by hand.
5. In the case the presser foot is lifted while the set value on the operation panel is a negative value,
the related parts can interfere with each other. So, be careful.
6. When you use the wiper with the sewing machine, the maximum lift of the presser foot should be 8.5
mm or less.
