change them:

new thread on the spindle and
tie
it to the end
of the original thread.
(2) Raise the presser foot lifter
to
lift
up the
presser
foot.
(3)
Press down the tension release lever
so
that
the
thread knot can pass through smoothly, draw
out the looper thread 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
is pulled
and caught in the needle’s
eye.
