needle, under the foot and to the back left.
Front Cover Seam Guide
1. The chain stitch (C-3) combined with the 3 thread
overlock is the most common 5-thread combination.
The mark closest to the needles indicates 5/8 inch
(16mm) from the cutting edge to the C-3 chain nee-
dle.
2. When using the left overlock needles (O-1) for either
a 3 or 4 thread overlock seam, the second mark from
the needles indicates 5/8 inch (16mm) from the cut-
ting edge to the O-1 overlock needle.
3. Use the right overlock needle (O-2) for 3 thread over-
lock seam and the third mark from the needles indi-
cates 5/8 inch (16mm) from the cutting edge to the
O-2 overlock needle.
4. Other marks on the front cover are for any custom
seam allowance.
Note: Be sure to set the width dial at the "M" setting for accurate seam allowances.
