1) Adjustment of the stitch length is performed with the operation panel.
For the setting procedure of the respective sewing patterns, refer to “6-5.
Setting the sewing pattern”.
Normal feed : Press +/– keys of to input.
Reverse feed : Press +/– keys of to input.
2) Numerical value of the operation panel is indicated in mm.
3) When performing the reverse feed stitching, press down reverse feed
control lever

. The sewing machine performs reverse feed stitching as
long as you keep the lever held pressed. The reverse feed control lever
will return to its home position and the sewing machine will run in the
normal stitching direction when you release the reverse feed control lever.
Example) In case of normal feed : +4 and reverse feed : –3,
the sewing range becomes normal feed +4 to –3. The maximum
amount of reverse feed becomes –3 when reverse feed control lever

is pressed. Besides, it is possible to adjust the stitch length of normal/
reverse feed up to 5 mm at the maximum by inputting.
Condensation stitching means that feed pitch amount is reduced and tie
stitching is performed by operating the reverse feed control lever at the
start or end of sewing.
1) Adjustment of the stitch length is performed with the operation panel.
Reverse feed : Press +/– keys of
to input. Tie stitching can be
performed by inputting the reverse feed amount to “0”.
2) Note that the tie stitching value is mere reference. Adjust the
condensation stitching while actually observing the finished seam.

It is possible for the gauge delivered (feed dog part No. : 40018430) to adjust
up to 5 mm of normal/reverse feed at the maximum. there is a possibility that
material is apt to fall in case of the process where the feed amount is small.
use the gauges such as feed dog and the like in accordance with the process.
there may be the cases where the feed amount of the operation panel and the actual sewing pitch are
different from each other in case of the use in the state other than the standard delivery or material used.
compensate the pitch in accordance with the sewing product.
