SETflNG UP
YOUR
MACHINE
1. Set
your
machine on a
sturdy, flat
surface.
2.
As your
machine
has
been thoroughly
oiled
at the
factory,
be
sure
to
wipe the
needle
plate
area
and bed
plate carefully
before
sewing a
garment.
It
is wise
to
practice on
a
scrap of
fabric so any
surplus oil
is absorbed.
3. FOOT CONTROL
Push
foot control
plug into the
connector
socket at the bottom
right-hand side
of
the machine.
4.
POWER/LIGHT SWITCH
Your
machine
will
not operate unless
the
power/light
switch is turned on.
This
same switch
controls both the
machine
power and sewing
light. When
leaving
your machine
unattended,
the machine
MUST
be
switched
off or
the plug
removed from
the
socket-outlet.
When servicing
the sewing machine,
removing
covers
or changing
lamps,
the
machine MUST be
disconnected
from the
supply by
removing the plug
from the
socket-outlet.
5.
OPENING
FRONT
COVER
To
open
front cover, pull it towards you as
illustrated.
It will latch automatically when closed.

PREPARATION
FOR
THREADING
EXTENSION
PLATES
AND
SPOOL
HOLDERS
Remove
the
spool holders
and
place the
extension plates
over
spool pins
beforehand.
For
large
cone spools use
the
rubber
spool
holders
with
the
wide
end
at
the
top, and
for
small
ones,
use
the
same
rubber
spool
holders
but
with
the
narrow end
at
the
top.
SPOOL
CAPS
When
using
domestic
cotton
reels,
place the
reel
directly
on
to
the
spool
pin.
Use
the spool
cap
to
keep
the
reel
in
place.
SPOOL
NETS
Spools
of
polyester
(filament>
thread
or bulk
nylon
thread
are
likely
to
work
loose
from
the
spool
pin
during
sewing, causing
tangling
or
irregular
thread feeding.
To
prevent
this,
use
the
spool
net
provided
to
keep
the
spool
in
place
as
illustrated,

Pressing
down and
holding
tension

ap
proaches
the needle
eye,
cut
off
the
knot
and
thread the

that
you plan
to
sew and
test to
sew in
th
following order.
1. Gently pulling
all the threads
to
the
lef

presser foot.
Rotate
the
haft
wheel towards
you a
few
times
to
see
if
th

2.
Start the machine
at low speed
and feed
i
test
fabric
under the
presser
foot by
slight
pushing
it forward.
(This can be done
wit
the
presser
foot
down on most
fabric
except
bulky
materials.)
Guide the
fabñ
gently as
machine automatically
feeds
th
material.
3. Check thread
tensions
by test
sewing
a
spare fabric.
4. At
fabric end, keep running machine
at
lo

THREE-THREAD
OVERLOCK
WITH
ONE
NEEDLE
In
addition
to
the
four-thread
overlocking
mainly
featured
on
this
machine,
it
is
possible
to
produce
simple
three-thread
overlock
seams
by
threading
only
ONE
needle.
Furthermore
it
is
also
possible to
achieve
two
different
seam
widths.
By
threading the
LEFT
needle
only
a
width
of 5
mm
will be
produced
and
by
threading
the
RIGHT
needle
only
a
width
of 2.8
mm
will
be
produced
