3. How to adjust thread tension
1. Standard rolled hem stitching
As adjustments are the same as 1-needle, 3-thread overedge stitching, refer to page 11.
2. Right looper thread wrapped rolled hem stitching (rolled hem variation)
• Correct thread tension
For light and medium weight fabrics which are dif¬
ficult to roll, a fine seam can be obtained by this
stitching.
To correctly adjust the thread tension, set the dials as follows from the standard thread tension dial sett¬
ings.
a. Turn the right looper thread tension dial (orange) one half graduation toward the (—) mark.
b. Turn the left looper thread tension dial (yellow) 2 ~ 3 graduations toward the (+) mark.
Slight adjustment will give better thread tensions.

4. How to sew
Sewing
• See page 8, “4. Chain off and test sew”.
• For rolled hemming, if a slight tension is applied to the material in the sewing direction, a finer seam
finish can be obtained.
• At the start of sewing, slightly pull the end of the chain off so it will not be entangled in the stitch.
• The minimum overedge stitch width that can be obtained for rolled hemming is approximately
1.5mm since the cutting width cannot be set below 3.5mm.
