3-Thread Overlock

3-thread serging works well - and conserves thread - for
edge-finishing most wovens and for seaming knits that don't
require the extra durability that a fourth thread provides.
It's easy to convert your Celebrate to serge with 3 threads by
simply eliminating either needle.
To convert your serger to wide 3-thread stitching (5.5-7.5
mm), snip the right-hand needle thread just above the needle
eye. To convert to narrow 3-thread stitching (3.0-5.0mm), snip
the left-hand needle thread. (fig. A) Remove the needle not
being used completely from the machine.
Re-tighten the needle clamp screw slightly to prevent the
screw from vibrating out. (Fig. B)
The tension on each thread is controlled by its own tension
dial. Turn the dial to a larger number to tighten or increase
tension, to a lower number to loosen or decrease tension. The
chart on the inside back cover suggests tension ranges for
3-thread stitching. On this chart, record specific settings for
your own machine.
Refer to the diagram to see what a balanced 3-thread stitch
should look like. The other diagrams show unbalanced
stitches and the tension adjustments necessary to correct
them.
