Baby Lock Ovation (BLES8) Instruction and Reference Guide - Manual (Page 56)

The 4-thread safety stitch is perfect for all types of woven fabrics ranging from fine to heavy weight
fabrics. This stitch is designed to seam and overlock the edge in one step, thus creating a garment
industry standard safety stitch. As well as woven fabrics, the 4- thread safety stitch is for stabilizing
knits, sweater knits and long seams on woven fabrics.
4-thread safety stitch is a combined stitch of a 2-thread overlock using subsidiary looper on the upper
looper and a 2-thread chain stitch. The 4-thread safety stitch itself can be 3 different seam widths,
depending on the chain/cover stitch needle position.
The varied widths can then work with different types of fabrics.
For 4-thread Safety Stitch:
1. Use standard cutting blade cover.
2. Thread the lower and chain loopers.
3. Thread one chain needle and the O-1 overlock needle. (see illustration)
4. Engage the subsidiary looper in the upper looper.
5. Engage the upper blade to cut the fabric. Set stitch width dial at 7.5."
6. Select "A" on the Stitch Selector.
7. Set Wave/Overlock Selector Lever on "OVERLOCK".
* For each size refer to settings chart on next page for the 4-thread safety stitch.
