OPTIONAL ACCESSORIES
from INSPIRA™
Optional presser feet specially prepared for this machine are
available at your dealer. The snap-on type presser foot used on
this machine allows easy removal and replacement.
Elastic Foot, 620 08 65-96
The Elastic Foot guides and stretches narrow elastic (6-12 mm,
¼-½") as you sew it to fabric. It is great for sewing for active
wear, lingerie and other elastic insertion techniques.
Blindhem & Lace Foot, 620 08 69-96
The Blindhem Foot is perfect for sewing invisible hems and
for applying lace. The hem is sewn, overcast and trimmed in
one step.
Beading Foot, 620 08 66-96
The Beading Foot smoothly guides beads and pearls through a
channel on the foot for easy application on garments or crafts.
Piping Foot, 620 08 67-96
The Piping Foot is perfect for inserting packaged piping into
seams and on edges for a tailored Ànish. The trim is sewn
between the two layers of fabric in one step. A groove under
the foot helps guide the piping. You can also create your own
piping for a custom Ànish.
The Piping Foot makes it fast and easy to cover cording with
fabric and to insert piping into seams for a professional look!
Taping Foot, 620 08 68-96
The Taping Foot is used to apply seam tapes to seams to
prevent stretching. It is especially good for stabilizing shoulder
seams. With this foot you can reinforce and construct seams in
one step.
Some fabrics have a lot of excess dye which can cause
discoloration on other fabric but also on your overlock machine.
This discoloring may be very difÀcult or impossible to remove.
Fleece and denim fabric, 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.

CONNECT FOOT CONTROL AND POWER SUPPLY
Among the accessories you will Ànd the power cord and the foot
control.
Note: Before plugging in the foot control, check to ensure that it is type
VSM Group AB, ”FR5” (see underside of foot control).
1. Pull out the cord from the foot control. Connect the foot
control to the front socket on the bottom right side of the
machine (A).
2. Connect the power cord to the rear socket on the bottom right
side of the machine (B). Plug the cord into the wall socket.
Before plugging your machine in, make sure the voltage is the same as
indicated on the plate under the machine. SpeciÀcations vary from country
to country.
3. Press the ON/OFF switch to ON to turn on power and light
(C).
Note: When the front cover is open the safety switch is activated and prevents
the machine from sewing, even if the foot control is pressed.
Note: To retract the foot control cord, unplug the foot control from the machine
(A). Pull the cord gently and release - the cord will retract itself into the foot
control.
POLARIZED PLUG INFORMATION
(For U.S.A. & Canada Only)
This appliance has a polarized plug (one blade wider than the other).
To reduce the risk of electric shock, this plug is intended to Àt in a
polarized outlet only way. If the plug does not Àt fully in the outlet,
reverse the plug. If it still does not Àt, contact a qualiÀed electrician
to install the proper outlet. Do not modify the plug in any way.

EXCLUSIVE SEWING ADVISOR™
Your overlock machine has the HUSQVARNA VIKING®
Exclusive SEWING ADVISOR™ feature (see page 13). When
beginning a sewing project, touch your fabric type and weight,
and select the stitch you desire. The machine automatically
makes the settings and gives recommendations based on that
fabric.
Below Ànd fabric selection recommendations.
Woven or Knit
The difference between woven and knit fabric is the way the
threads are put together. Woven fabrics are made of two thread
systems, warp lengthwise and weft crosswise, that intersect at
right angles. A knit fabric is made of one thread system with
interlaced stitches. A knit fabric usually has stretch.
As a general rule, enter Woven for stable fabrics that have no
stretch and Stretch for fabrics that have stretch.
