The
Needle
Threader
Operation
of
the needle
threader
is extremely easy. Simply make sure
that
the
needle
is
at
its highest position,
i.
e.
that
the
lower hole
of
the ascending toke-
up
lever d (Fig.
67)
is
in
line with
the
bottom
edge
of
the
top
cover. Then lower
the sewing foot
and:
1. With your left hand, push needle
threader
control p down until
threader
prong w penetrates the needle eye. Keep the control
in
this position.
2.
Hold the thread loosely
and
lead
it from the left
around
the small pin q,
then
place
it behind the hook of
threader
prong
w.
3. Release control p slightly until prong w reverses
and
pulls the
thread
through the needle eye (Figs. 68-71
and
96}.
4.
Jerk control p down
again
so
that
the thread
loop
will fall off prong
w.
Pull
the
thread
through the
needle
eye by hand
and
release control
p.
The needle
is
threaded from front
to
bode:.
Turn
the
balance
wheel to
draw
the
bobbin
thread
up through the needle
hole,
and
place
both threads bock under the sewing foot.
Stitching
Oft
the
Machine
Begin
to
stitch off the machine on a medium-grade fabric. Whoever wonts
to
be
sure
that
his customer will
be
really satisfied with the performance
of
his
machine,
will
also
try it
out
on delicate
and
heavy fabrics. Establish the correct
needle thread tension while sewing
on
these materials with straight
and
zigzag
stitches.
The complete
range
of
sewing tests includes stitching across tucks
as
well
as
sewing forward
and
backward with the machine
set
for straight stitches
of
varying
lengths.
