Needle thread tension To ensure perfect
sewing results,
the
needle and bobbin thread
tensions must
be
perfectly tuned
to
each
other
. The normal setting
for
utility
stitches is
in
the
range 4 - 5.
Check
the
tension
with
a broad zigzag stitch.
The threads must
be
interlaced between
the
two
fabric plies.
If
the
needle thread tension is
too
high,
the
threads are interlaced above
the
top
fabric ply.
If
the
needle thread tension is
too
low,
the
threads are interlaced
below
the
lower
fabric
ply.
The adjustment
of
the
bobbin thread tension
is described on page

Sewing
aid
for thick seams
To ensure a consistent feed when beginning
sewing we recommend supporting
the
presser
foot
on a piece
of
fabric
of
the
same height
as
the
workpiece.
Topstitching
Straight
stitch G can
be
sewn using any
of
15
various needle positions
in
such a
way
that
you can always guide
the
sewing
foot
along
the
fabric edge
for
top-stitching
work
. The
top-stitch
width
is
determined by
the
needle
position. If you wish
to
top-stitch
at a wi
der
wi
dth
than
this
, si
mply
guide
the
fabric
along
the
guide marks on
the
needle plate,
or
use
edge guide (standard accesory No. 8). The
edge guide is inserted into
hole C and is secu-
