Some fabrics have a lot of excess dye which can cause discoloration on other fabric but also on
your sewing machine. This discoloring may be very difficult or impossible to remove.
Fleece and denim fabric in especially red and blue often contain a lot of excess dye.
If you suspect that your fabric/ready-to-wear garment contains a lot of excess dye, always pre-
wash it before sewing to avoid the discoloring.

Procedures
Unpacking
1. Place the machine on the table or cabinet and

2. The machine is delivered with a hard protec-
tive cover, a foot control, an accessory box, a

3. Wipe the machine, particularly around the
needle and needle plate to remove any soil
before sewing.
Packing Away After Sewing

machine.
2. Wind the cords around your hand and place
the foot control cord in the foot control
storage space and the main cord in the pocket

Procedures
Connecting the Foot Control
Among the accessories you will find the foot con-
trol cord and the main cord.
1. Remove the foot control cord. Place the foot
control on its narrow side. Fit the plug into the
socket inside the foot control compartment.
2. Push it firmly to make sure it is properly
connected. This operation is only necessary
the very first time you are going to use the
machine.
3. To correctly turn away the cord, place it into
the slot.
Note: Before plugging in, check to ensure that
the foot control is of type ”FR4”.
Connecting to the Power
Supply
On the underside of the machine you will find
information about the power supply (V) and the
frequency (Hz). Check the power supply setting
in the machine to ensure that this agrees with the
main supply before you connect the machine.
1. Connect the foot control cord to the first
socket on the bottom right side of the
machine.
2. Connect the main cord to the back socket on
the bottom right side of the machine.
3. When you press the power switch, both the
machine and the light are switched on.
For the USA and Canada
This Sewing Machine has a polarized plug (one
blade wider than the other). To reduce the risk
of electric shock, this plug is intended to fit in a
polarized outlet only one way. If the plug does
not fit fully in the outlet, reverse the plug. If it
still does not fit, contact a qualified electrician to
install the proper outlet. Do not modify the plug
in any way.

Procedures
Accessory Box
1. Open the accessory box by placing your finger
in the space on the top and lift upward.
2. In the accessory box there is a special tray for
presser feet and bobbins plus space for other
accessories.
3. Store the presser feet and the bobbins in the
tray from the beginning so they are always
easily accessible (refer to the figure).
Extended Sewing Surface
1. Slide the accessory box onto the machine to
provide a larger flat work surface.
2. Slide the accessory box to the left when you
wish to remove it and use the free arm.
3. To facilitate sewing trouser legs and sleeve
hems use the free arm. The free arm also
allows you to darn socks (darning foot is an
accessory).
4. To replace the accessory box, slide it tight onto
the machine.
An extension table is also available as an accessory
to provide an even larger sewingsurface.

Procedures
Spool Pin
The machine has spool pins suitable for all types
of thread. The main spool pin (a) is adjustable –
the thread reels off the stationary spool. Place the
spool so that the thread reels counter-clockwise.
There are two spool holders on the spool pin.
With narrow thread spools, the small holder (b)
is placed in front of the thread. If you use large
thread spools, the large holder (c) is placed in
front of the thread.
Slide the correct size spool holder in place so the
flat side is pressed firmly against the spool. No
space between spool holder and spool.
There is also a separate spool pin (d) to be
attached onto the machine. The fingers on the
extra spool pin fit into the two holes to the right
of the fixed spool pin. Push downward to snap
in place.
The large spool holder (c) is placed under the
thread. This spool pin is used when winding a
bobbin from a second spool of thread or for a
second spool when sewing with a twin needle.

Procedures
Threading the Upper Thread
Make sure the presser foot is raised and the needle
is in the up position
1. Pull the spool pin out. Place the thread on the
spool pin and the spool holder on the spool
pin as described. Push the spool pin back in.
2. Bring the thread in the direction of the arrow
under the thread guide (a) and over the thread
guide (b).
3. Bring the thread down between the thread
tension discs.
4. Continue threading by drawing the thread from
the right into the slot on the take-up lever.
5. Thread last guide just above the needle.
6. The needle is threaded from front to back. The
white on the presser foot ankle makes it easy to
see the eye of the needle.
7. Place thread under the presser foot and into
the thread knife where it is cut.
Bobbin Winding with the
Machine Threaded
Make sure that the presser foot is up and the
needle is in the highest position.
Note! Do not use a plastic presser foot when
bobbin winding.
1. Place your empty bobbin with the small mark
outwards on the bobbin spindle on the
front of the machine. Bring the bobbin spindle
down.
2. Pull the thread from the needle under the
presser foot and to the right over the thread
guide (c).
3. Start from above and wind a few turns of
thread around the bobbin. Cut off the thread
on the thread knife (d).
4. Press the foot control. When the bobbin win-
ding is finished, remove the bobbin, cut off the
thread and bring the bobbin spindle up.
Note! We do not recommend winding specialty
threads such as clear nylon or other stretchy
threads through the needle. Instead see ”Bobbin
winding – vertical spool pin”.

Placing the Bobbin in the
Machine
1. Remove the bobbin cover by sliding it towards
you.
2. Place the bobbin in the bobbin case with the
mark facing up and the thread to the left
of the bobbin. The bobbin will then rotate
counter clockwise while pulling out the thread.
3. Place your finger on the bobbin to keep it
from turning as you pull the thread firmly to
the right and then to the left into the tension
spring (a) until it ‘‘clicks’’ into place.
