(2) Turn the hand wheel toward you until needles are fully raised.
(3) Open front cover and remover left needle. See page 18.
(4) Set stitch length between 1.0-2.0 mm. See page 16. Also ensure that differential control is set at
'N' position.
(5) Adjust stitch width, as shown on page 17.
(6) If not already threaded re-thread the machine.
(7) Place fabric under presser foot and start to sew.
Always test the stitch and tension settings on scrap fabric before sewing on an actual garment.

ALWAYS remember to re-set the special foot for normal serging after you have finished your rolled
edge procedure.

[ ROLLED EDGE ]

With a rolled edge the loops formed by the
lower looper thread should be pulled to the
underside of the fabric. This is done by setting
the tensions as shown on page 23.

[ NARROW EDGE ]

For seams on sheer or lightweight fabrics, set
tensions as shown on page 23 for a balanced
tension.
