3-3. Sewing continuous backtack stitches
Setting continuous backtack stitches
When the AUTO key is pressed to turn on the automatic sewing function, operation will be carried out
automatically from continuous backtack sewing through to thread trimming just by depressing the
treadle once, without needing to keep it depressed continuously.
If the treadle is simply depressed continuously, the number of stitches set for A, B, C and D
will be sewn in a single cycle, the thread will be trimmed automatically and then the needle
bar will stop in the needle up position.
・ If the treadle is returned to the neutral position while continuous backtacking is being
carried out, the sewing machine will stop at the point where the treadle returns to the
neutral position. If the treadle is depressed again, operation will resume from the point
where it was interrupted.
・ If the indicator of the thread trimming lock key is illuminated, the sewing machine will
stop in the needle up position without thread trimming being carried out.
