way

to

change

them:

(1)

Cut

the

thread

in

(2)

Raise

the

presser

foot

lifter

to

lift

up

the

presser

foot.

(3)

Press

down

the

tension

until

the

thread

knot

comes

to

about

10

cm

past

the

presser

foot.

(4)

When

changing

the

needle thread,

cut

off

the

thread

knot

before

it

reaches

the

eye

of

the

needle

to

avoid

bending

the

needle

as

the

knot
