Sewing; Stitch Overview; 4-Thread Overlock - Singer S14-77 Instruction Manual

SEWING

On your overlock machine, different stitches are obtained by combining different needle positions, threading methods, tension
settings, and the use of the 2-thread overlock converter.
See Getting Ready to Sew, page 7, for references on how to set your machine.

Stitch Overview

The settings shown in the table below are our recommendations based on normal conditions. It may be necessary to adjust the
thread tension depending on the stitch, type of fabric and thread you are using. For best results make tension adjustments in small
increments of no greater than half a number at a time. Always test sew on a sample of your fabric before sewing on your project.
In the table below, different fabric weights and types are explained. For you to better understand how the stitches are formed, each
of the threads are displayed in different shades of grey.
