This
machine
uses
needles classified
as
AA,
or 15x1
which
can be
obtained
in
various
sizes
for
different
size threads and
purposes.
See Chart,
Page
7.
It is
important
that
the
proper
size
of
thread
be
used.
Make
certain
that the
same
size and
quality
of thread
is
used
in both
the
upper
spool
and
the
bobbin.
This will
prevent faulty
sewing.
“Bargain”
thread is
poor
economy.
In
many
cases,
such thread
has tiny
knots
which
interfere
with the
free flow
of the thread
through
the thread
ing mechanism
and
needle.
High
quality
thread is
most
desirable
to
achieve
perfect
sewing
results.
HOW
TO CHOOSE
NEEDLE
AND
THREAD
The quality of the
seam made by your
sewing
machine depends
largely upon the
proper
selection of needle and
thread size.
Both should be
matched as closely as
pos
sible to the type
of fabric
you
intend
to sew.
See
Chart, Page
7. Heavy
material requires
a
thicker
needle and
coarser thread,
while
finer fabric
calls for
a
thinner needle
and
finer thread.
Using
a
needle that
is
too
thick
will leave marks
on the
cloth. A needle
which is
too thin will not allow
the
thread
to
pass
freely through
the eye
of
the needle.
Always
make
sure that the
needle in your
machine
is
not bent
and does not
have
a
blunt or
hook-shaped
point
It is highly
important that
the correct
SIZE of needle
be
chosen
for
the sewing to
be
done.
Refer
to Chart,
Page 7.
This
Chart, in fact,
indicates the
proper SIZE
of needle for various
types
of
sewing.
Equally
important, when
purchasing re
placement
needles, make
certain that they
are the
correct
LENGTH. The
diagram
below shows
the correct LENGTH

to scale.

it is
impossible
to
secure

sewing
results.
In fact,
a
needle
of incorrect

will
cause
you
endless
trouble.
