To adjust the stitch length, turn the stitch length adjusting knob and move the knob upwards or downwards. Differential feed adjusting knob (to adjust the feeding for gathering or stretching) To adjust feeding for gathering or stretching, turn the differential feed adjusting knob upward or downward.

Left hand needle thread (Yellow) Threading aids such as tweezers, needle threader, and looper threader which are provided as accessories will be very useful in threading work. To lay the thread correctly between the tension discs, pull the thread lightly with both hands. Insert the needle threader through the needle eyelet or looper eyelet, then thread the needle threader. Place the spool on the spool holder pin right under blue marking on the retractable support rod thread guide.
