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

Example) In case of normal feed :
the sewing range becomes normal feed +4 to –3. The maximum amount of
reverse feed becomes –3 when reverse feed control lever 1 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

2) Note that the tie stitching value is mere reference. Adjust the condensation
stitching while actually observing the finished seam.
3) Numerical value of the operation panel is indicated in mm.
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
