Twin

needles

Twin

needles

are

used

for

forming

raised

seams

as

well

as

for

sewing

decorative

stitches

using

two

threads.

The

twin

needle

is

inserted

in

the

same

way

as

a

regular

needle.

When using

a

twin

needle

you

can

use

any

design

on

the

middle

scale

of

the

Program

Selector.

Make

sure

that

the

zigzag

width

is

not

set

for

more

than

2;

otherwise

you

will

break

the

needle.

Slowlymove

the

handwheel

for

an

entire

pattern

so

that

you

are

sure

the

needle

will

not

hit

the

needle

plate.

Also

check

the

stitch

length

to

be

sure

the

stitches

are

not

too

close.

Place

a

spool

of

thread

on

each

spool

pin.

Thread

both

threads through

the

upper

thread

guides.

Bring

each

thread

around

the

tension

dial

with

the

threads

on

each

side

of

the

tension

plate.

Be

sure

to

lock

both

threads

in

the

tension

spring.

Insert

each

thread

through

separate

holes

in

the

take-up

lever.

Both

threads

go

through

the

front

thread

guide

but

they

sep

arate

at

the

needle

thread

guides.
