Presser Feet
Utility Foot A
Attached on the machine upon delivery. This foot is used mainly for straight stitching and zigzag
stitching with a stitch length longer than 1.0.
Decorative Stitch Foot B
When sewing decorative stitches or short zigzag stitches and other utility stitches with less than 1.0
mm stitch length, use this foot. The tunnel on the underside of the foot is designed to feed smoothly
over the stitches.
Buttonhole Foot C
This foot is used for sewing buttonholes step by step. Use the guide lines on the toe of the foot to
position the garment edge. The two tunnels on the bottom of the foot ensures a smooth feed over
the buttonhole columns. The finger on the back of the foot holds cording for corded buttonhole.
Blind Hem Foot D
This foot is used for blind hem stitches. The inner edge of the foot guides the fabric. The right toe
of the foot is designed to ride along the hem edge.
Zipper Foot E
This foot can be snapped on either to the right or to the left of the needle, making it easy to sew
close to both sides of the zipper teeth. Move needle position to the right or left to sew closer to the
zipper teeth or for covering large cording.
Edging Foot J
This foot is used for overcasting and seam/overcasting. Stitches form over the pin which prevents
puckering at the edge of the fabric.
One-Step Buttonhole Foot C
This foot has a space in the back for a button used to set the size of the buttonhole. The machine
will sew a buttonhole to fit that button size. Used to sew buttonholes up to 25 mm.
Self-Adhesive Glide Plate
If sewing on foam, vinyl, plastic, or leather, the material can stick to the foot and prevent the sewing
machine from feeding properly. When using any of the above materials, sew on a piece of scrap
fabric, to make sure the machine feeds smoothly. If not, fasten the self-adhesive glide plate to the
underside of the presser foot.

2 Preparations
Unpacking
1. Place the box on a sturdy, flat surface. Lift the machine
out of the box and remove all packing material and the
plastic bag.
2. To remove the storage box, turn the locking device
located at the rear side of the box to the left and push the
box forward.
3. Wipe the machine, particularly around the needle and
needle plate to remove any oil before sewing.
Note: Your HUSQVARNA VIKING® JADE™ 20 machine is
adjusted to provide the best stitch result at normal room temperature.
Extreme hot and cold temperatures can affect the sewing result.
Note: Some fabrics have excess dye which can cause discoloration on
other fabrics or on your sewing machine. This discoloration may be very
difficult or impossible to remove.
Fleece and denim fabric, especially red and blue, often contain 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 prevent discoloration of
your machine.
12 2 Preparations

Connect the Power Cord and Foot
Control
Among the accessories you will find the power cord and the
foot control.
Note: Consult a qualified electrician if you are in doubt about how to
connect the machine to the power source. Unplug the power cord when
the machine is not in use.
For this sewing machine, foot control model C-9002
manufactured by CHIEN HUNG TAIWAN Ltd must be
used.
1. Connect the foot control cord 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.
3. Press the ON/OFF switch to ON to turn on power and
light (C).
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.
Pack Away After Sewing
1. Press the ON/OFF switch to “O”.
2. Unplug the cord from the wall socket and then from the
machine.
3. Unplug the foot control cord from the machine. Wind
the cord around the foot control and place it inside the
storage box.
4. Place all accessories in the accessory tray. Slide the tray
on to the machine around the free arm.
5. Place the storage box on the machine and turn the
locking device to lock the box in place.
LED Lights
Your machine has LED lights which distribute the light
evenly over the sewing area and eliminate shadows.
2 Preparations 13

Free Arm
To use the free arm, slide off the accessory tray. Remove the
tray by sliding it to the left.
Use the free arm to facilitate sewing pant legs and sleeve
hems.
To replace the accessory tray, slide it onto the machine until it
fits in place.
Mounting Machine in Sewing Cabinet
There are two holes on the underside of the machine
designed for mounting the machine into a sewing cabinet.
Attach the machine with M6 screws.
Spool Pins
Your machine has two spool pins, a main spool pin and an
auxiliary spool pin. The spool pins are designed for all types
of thread. The main spool pin is adjustable and can be used
both in a horizontal position (the thread reels off the spool)
and a vertical position (the thread spool rotates). Use the
horizontal position for normal threads and the vertical
position for large spools or specialty threads.
Horizontal Position
Place a felt pad and the thread spool on the spool pin. Make
sure that the thread reels off from the front of the spool (A)
and slide on a spool cap.
Note: Not all thread spools are manufactured in the same way. If you
experience problems with the thread, turn the spool so that the thread
reels off in the opposite direction or place the thread in the vertical
position.
Depending on the size of thread spool, reverse the direction
of the spool cap (B).
Use the small cap when you use cross wound thread (C).
Set the thread net over the spool if thread reels off too easily
(D).
14 2 Preparations

Vertical Position
Raise the spool pin to the vertical position. Place a felt pad
under the thread spool. This is to prevent the thread from
reeling off too fast. Do not place a spool cap on top of the
spool pin as that would prevent the spool from rotating.
Auxiliary Spool Pin
The auxiliary spool pin is used when winding a bobbin
thread from a second spool of thread or for a second spool
when sewing with a twin needle. Insert the auxiliary spool pin
into the hole at the top of the machine (A). Place a felt pad
under the thread spool.
Threading the Machine
Make sure that the presser foot is raised and the needle is in
its highest position.
1. Place a felt pad and the thread spool on the spool pin
and fit a spool cap of the right size and direction.
Note: Hold thread with both hands to prevent it from slacking
while threading. This ensures that the thread will be positioned
properly in the threading path.
2. Pull the thread under the thread guide (A) from the right
to the left.
3. Pull the thread from the right to left along the slot.
4. Pull the thread between the tension discs (B).
5. Thread down through the right-hand threading slot and
then upwards through the left-hand threading slot.
6. Bring the thread from the right into the take-up lever (C)
and down in the left-hand threading slot into the needle
thread guide (D).
7. Thread the needle.
2 Preparations 15

Needle Threader
The needle threader allows you to thread the needle
automatically. The needle must be in its highest position to
use the built-in needle threader. Press the needle up/ down
button to make sure the needle is fully raised.
We also recommend lowering the presser foot.
1. Use the handle (A) to pull the needle threader all the way
down. Metal flanges encase the needle and a small hook
will pass through the needle eye.
2. Place the thread from the back over the thread guide (B)
and under the small hook (C).
3. Let the needle threader gently swing back. The hook
pulls the thread through the needle eye and forms a loop
behind the needle. Pull the thread loop out behind the
needle.
4. Raise the presser foot and place the thread under it.
Note: The needle threader is designed to be used for size 70-120
needles. You cannot use the needle threader for size 60 needles or
smaller, wing needles or twin needles.
There are also some optional accessories that require manual threading
of the needle.
When threading the needle manually, make sure that the needle is
threaded from front to back.
Cutting the Thread
Once you have finished sewing, cut the threads by raising the
presser foot and pulling the threads from the front to the
back into the thread cutter on the left side of the machine.
16 2 Preparations

Threading for Twin Needle
Replace the sewing needle with a twin needle. Make sure that
the presser foot is raised and the needle is in its highest
position.
1. Thread the first thread as described in Threading the
Machine, page 15.
2. Thread the needle eye by hand from front to back.
3. Insert the auxiliary spool pin and slide on a felt pad. Place
the second thread on the spool pin.
4. Bring thread to the left and pull thread into the thread
guide (A) from back to front.
5. Thread the second thread the same way as the first.
6. Make sure that one thread is inside the needle thread
guide and the other one outside.
7. Thread needle eye by hand from front to back.
Note: Twin needle is not included with the machine.
Note: The weight and irregular surface of specialty threads, like
metallics, can cause increased tension on the thread. Reducing the tension
will prevent needle breakage.
Note: When using a twin needle, the stitch width might need to be
reduced to prevent damage to the twin needle, needle plate or presser foot.
How much you need to reduce it depends on the stitch position, the stitch
width and/or the size of the twin needle.
Note: Do not use asymmetrical twin needles, since they may damage
your sewing machine.
2 Preparations 17

Bobbin Winding
Winding From Horizontal Position
1. Place the felt pad and thread spool on the spool pin in
horizontal position. Slide on a spool cap of the right type
and direction.
2. Place the thread under the thread guide (A) from right to
left. Pull the thread to the rear and around the thread
guide (B) from left to right, then around thread guide (C)
and into the notch (D).
3. Pull thread to the right and then through the thread guide
(E) from front to back. Pass thread under tension disc (F)
in clockwise direction.
Note: Make sure the thread is pulled securely inside the tension disc
for correct thread tension.
4. Thread through the hole in the empty bobbin (G) from
the inside to the outside.
5. Place the bobbin on the bobbin winder spindle.
6. Push the bobbin spindle to the right to wind. The letters
"SP" is shown on the LED display, indicating that bobbin
winding is active. Press the foot control or the start/stop
button to start winding the bobbin. Hold the end of the
thread firmly when starting to wind.
When the bobbin is full, release the foot control or press
the start/stop button again to stop. Push the bobbin
spindle to the left. Remove the bobbin and cut the thread
using the bobbin thread cutter (H).
Note: When winding the bobbin from auxiliary spool pin, do not hook
thread to the guide (C) and notch (D).
18 2 Preparations

Winding Through the Needle
Make sure the presser foot is raised and the needle is in its
highest position.
Note: Use a metal presser foot when bobbin winding from the needle.
Pull the thread from the needle under the presser foot and to
the right through the thread guide (A).
Follow step 4–6 under Winding From Horizontal Position.
Inserting the Bobbin
Make sure the needle is fully raised and the machine is turned
off before inserting or removing the bobbin.
1. Open the bobbin cover by pushing the release button to
the right (A). Remove the cover (B).
2. Insert the bobbin in the bobbin case with the thread
running in a counterclockwise direction.
3. With a finger held gently on top of the bobbin, pull the
thread into notch (C). Then pull the thread at arrow
markings into the needle plate thread guide from (C) to
(D). Pull the thread at the arrow markings into the needle
plate thread guide from (D) to (E). To cut off excess
thread, pull thread to the right, over the blade (E).
4. Replace the bobbin cover.
2 Preparations 19

Thread Tension
To set the thread tension, turn the dial on top of the
machine. Depending on the fabric, batting, thread, etc, the
tension may need to be adjusted.
See Stitch Overview, page 9 for thread tension
recommendations.
Correct tension
For the best stitch appearance and durability, make sure the
needle thread tension is correctly adjusted, i.e. for general
sewing, the threads evenly meet between the two fabric
layers.
Tension too tight
If the bobbin thread is visible on the top side of the fabric,
the needle thread tension is too tight. Reduce the needle
thread tension.
Tension too loose
If top thread is visible on the underside of the fabric, the
needle thread tension is too loose. Increase the needle thread
tension.
For decorative stitches and buttonholes, the top thread
should be visible on the underside of the fabric.
Make a few tests on a scrap piece of the fabric you are going
to sew and check the tension.
Lowering the Feed Teeth
The feed teeth are lowered when you move the switch on the
back of the free arm to the left. Move the switch to the right
if you wish to raise the feed teeth. The feed teeth will raise as
you begin to sew. The feed teeth should be lowered when
sewing on buttons and for free motion sewing.
