5. Set the stitch length control lever.
- Tapes: between "3" and "4"
- Elastics: "4"
6. Adjust the presser adjusting dial
2
- at "0" when sewing with tapes.
- at desirable number for contraction when
sewing with elastics.
NOTE:
Contraction will be increased with larger number.
7. Make trial sewing and adjust thread tensions.
Example of proper sewing seam:
<B>
<A>
<C>
<D>
<A> Surface
<B> Tape
<C> Surface
<D> Elastic
NOTE:
Thread tensions are similar to normal overedging
when sewing with tapes.
It is recommendable to have a stronger tension for
under looper and over looper for beautiful finish.
It is advisable to make trial sewing on each material
/ thread due to different contraction.

comes through the tunnel.
2. Sew at slow speed while guiding the strand of
pearls and fabric by hand.

NOTE:
Thread tension is easy to loosen especially for small
size pearls. Retract movable stitch tongue for better
stitching.
