and other materials as described in this instruction manual. Any other use is not considered proper. BERNINA
assumes no liability for consequences resulting from improper use.
Equipment and Scope of Delivery
Example images are used in these instructions for the purposes of illustration. The machines shown in the
images and the accessories shown therefore do not always match the actual items included with your
machine. The supplied accessory can vary depending on the country of delivery. You can acquire any
accessories mentioned or shown that are not included in the scope of delivery as optional accessories from a
specialist bernette dealer. Further accessories can be found at www.bernette.com.
For technical reasons and in order to improve the product, changes may be made to the equipment of the

Servicing of Double-insulated Products
In a double-insulated product two systems of insulation are provided instead of grounding. No grounding
means is provided on a double-insulated product nor should a means for grounded be added to the product.
Servicing a double-insulated product requires extreme care and knowledge of the system and should only be
done by qualified service personnel. Replacement parts for a double-insulated product must be identical to
the original parts in the product. A double insulated product is marked with the words: «Double-Insulation»
or «double-insulated».
The symbol may also be marked on the product.
Environmental Protection
BERNINA International AG is committed to environmental protection. We strive to minimize the
environmental impact of our products by continuously improving product design and our technology of
manufacturing.
The machine is labeled with the symbol of the crossed-out wastebin. This means that the machine should
not be disposed of in household waste when it is no longer needed. Improper disposal can result in
dangerous substances getting into the groundwater and thus into our food chain, damaging our health.
The machine must be returned free of charge to a nearby collection point for waste electrical and electronic
equipment or to a collection point for the reuse of the machine. Information on the collection points can be
obtained from your local administration. When purchasing a new machine, the dealer is obliged to take back

Thread Selection
For a perfect sewing result, thread and fabric quality play an important role.
We recommend purchasing quality threads to achieve good sewing results.
• Cotton threads have the advantage of being a natural fiber and therefore are especially suitable for
sewing cotton fabrics.
• Mercerized cotton threads have a slight sheen that is not lost with washing.
• Polyester threads have a high tensile strength and is particularly colorfast.
• Polyester threads are more flexible and are recommended where a strong and elastic seam is required.
• Rayon threads are made of natural fibers and have a brilliant sheen.
• Rayon threads are suitable for decorative stitches and achieve a more beautiful effect.
Needle/Thread Combination
The needle/thread combination is correct, when the thread fits perfectly into the long
groove and goes easily through the needle eye. The thread can be optimally sewn.
The thread can break and skipped stitches can occur when there is too much clearance in
the long groove and the needle eye.
The thread can break and get stuck when the thread scrapes against the edge of the long
groove not fit well into the needle eye optimally.

2.1 Connection and Switching On
Connecting the Machine
To ensure safe operation of the machine, only the supplied mains cable may be used. The supplied power
cable is designed for the voltage range applicable in the country of use. If the machine is to be used in a
country other than the country of origin, the power cable suitable for that country must be obtained from
the Authorized bernette dealer.
The power cable for the USA and Canada has a polarized power plug (one contact is wider than the other).
To reduce the risk of an electric shock, the plug can only be inserted into the socket in one way. If the power
plug does not fit in the socket, reverse then insert the power plug. If the reversed power plug still does not
fit, an electrician must install an appropriate socket. Do not modify the power plug in any way.
> Insert the device connector of the power cable into the machine's power cable connection.
> Insert the power plug of the power cable into the socket.
Use of the Power Cable (only USA/Canada)
The machine has a polarized plug (one contact is wider than the other). To reduce the risk of electric shock,
the plug can only be plugged into the socket in one way. If the plug does not fit into the socket, turn the
plug. If it still does not fit, an electrician needs to be called to install an appropriate outlet. Do not modify the
plug in any way.
Connecting the Foot Control
The cable of the foot control is rolled up on its underside.
> Unroll the cable of the foot control to the desired length and fix it in the cable holders of the foot

Using the Spool Net
The spool net holds the thread on the thread spool and prevents the thread from knotting and breaking. The
spool net is only used with the horizontal spool holder.
> Pull the spool net over the thread spool. Ensure when doing so that the spool net does not slip off the
thread spool, e.g. double-insert the net over the thread spools or insert a part of the net into the thread
spool at the rear.

Setting the Presser Foot Pressure
The presser foot pressure is designed to adjust the pressure of the presser foot optimally to the fabric
thickness. When working with thick fabrics, it is recommended to reduce the presser foot pressure. This
provides the advantage that the fabric can be moved more easily. When the presser foot pressure is set
below 0, the presser foot even lifts to give more space to the thick fabric. When working with thin
fabrics, it is recommended to increase the presser foot pressure. This provides the advantage that the
fabric cannot be moved too easily under the presser foot.

5.2 Dual feed
It is recommended to match the presser foot pressure with the fabric. The thicker the fabric, the lower
the presser foot pressure.
The Dual Feed feeds the fabric from above and from beneath simultaneously. This provides an even and
careful feed forward even for smooth and thin materials. Striped and checkered patterns can be matched
perfectly by even feeding.
Application of the Dual Feed
In general, the Dual Feed is used for the following sewing projects:
• Sewing: All sewing applications with difficult fabrics such as for seams, zippers.
• Patchwork: With accurate stripes, blocks and with decorative stitches up to a stitch width of 7 mm.
• Appliqués: sewing appliques, ribbons and bias binding.
Difficult-to-work-with fabrics are:
• Velvet, normally sewn with the grain
• Toweling
• Jersey, especially when sewing it crosswise to knit
• Fake fur or coated fake fur
• Fleece-types of fabrics
• Batted fabrics
• Stripes and checks
• Curtain fabrics with pattern repeats
«Sticky» fabrics are:
• Imitation leather, coated fabrics
Use the Dual Feed
When working with the Dual Feed, only use presser feet with the rear opening.
> Raise the presser foot.
> Swing the DF mechanism forward under the back of the presser foot until it clicks in position.
> Raise the presser foot.
> Pull down the DF mechanism and swing it to the rear to disengage.

5.3 Regulating the Speed
The sewing speed can be adjusted infinitely variable with the slide.
> Move the slide to the left to reduce the sewing speed.
> Move the slide to the right to increase the sewing speed.
5.4 Adjusting the Upper Thread Tension
The default setting of the upper thread tension is set automatically as soon as a stitch pattern is selected.
When using different types of sewing threads, the upper thread tension may vary. It may therefore be
necessary to adjust the upper thread tension individually according to the sewing project as well as the
desried stitch.
The higher the upper thread tension is set, the tighter the upper thread is tensioned, and the bobbin thread
is pulled deeper into the fabric. When the upper thread tension is low, the upper thread is less tightened,
and the bobbin thread is pulled up less into the fabric.
Alteration of the upper thread tension affect the currently stitch pattern. Permanent alterations of the upper
thread tension for the sewing can be made in the Setup Program.

7 Decorative Stitches
7.1 Overview Decorative Stitches
Easier or more difficult decorative stitches come into their own depending on the type of fabric.
• Decorative stitches which are programmed with simple straight stitches are particularly appropriate for
light-weight materials, e.g. the Decorative stitch No. 142.
• Decorative stitches which are programmed with triple straight stitches or with a few satin stitches are
particularly appropriate for medium-weight materials, e.g. Decorative stitch No. 152.
• Decorative stitches which are programmed with satin stitches are particularly appropriate for medium-
weight materials, e.g. Decorative stitch No. 101.
For a perfect stitch formation, it is of advantage to use the same thread color for upper and bobbin thread
and a stabilizer. With pile or longfiber materials, it is recommended to use an additional water-soluble
stabilizer, which can be easily removed after sewing, on the right side of the fabric.
Decorative Stitch Stitch Number Name

7.2 Altering the Stitch Density
With satin stitches (e. g. No.101) the stitch density can be altered. A larger number means a larger stitch
distance, i.e. the stitch is sewn less densely. For a high stitch density, the number must be decreased. Stitch
density 1 is the minimum. The set stitch pattern length is not changed by altering the stitch density.
> Select the satin stitch.
> Tap «i-Dialog».
> Tap «Altering the Pattern Length/Stitch Density».

7.3 Sewing Cross Stitches
Cross stitch embroidery is a traditional technique and an addition to the other decorative stitches. If the cross
stitches are sewn on fabrics with a linen structure, they look as if they were hand-stitched. When cross
stitches are sewn with embroidery yarn, the stitch pattern appears fuller. Cross stitches are particularly used
for home furnishing, trimmings on garments and embellishing in general. As every following line refers to
the first row, it is important to stitch the first row in a straight line.
> Attach the Zigzag Foot (DA) or the Embroidery Foot (JK) or the Open embroidery Foot (DN) (optional
accessory).
> Select a cross stitch of the Decorative stitch No. 125-132 and combine it as desired.
> Stitch the first row using the seam guide to sew a straight line.
> Stitch the second row next to the first at a distance of one presser foot‘s width or using the seam guide.

8.1 Overview Alphabet
Block, Double block and Script alphabets can be sewn in two different sizes, in upper and lower case letters.
For a perfect stitch formation, it is recommended to use the same thread color for upper and bobbin threads.
The fabric can be reinforced with embroidery stabilizer on the wrong side. Use an additional, water-soluble
stabilizer on the right side of pile or napped fabrics.

recommended to use a monofilament thread for the upper thread and a cotton embroidery thread for the
bobbin thread. The sewing speed should be moderate to prevent the monofilament from breaking. If
required, the upper thread tension and the balance can be adjusted to the sewing project and the desired
quilt stitch.
> Attach the Embroidery Foot (JK) / Zigzag Foot (DA).
> Tap «Quilt Stitches».
> Select the Hand Quilt Stitch No.1004 or 1005.

10.4 Guiding the Quilt Work Freely
Quilting gloves with rubber nubs make it easier to guide the fabric.
It is recommended to use the extension table (optional accessory) and the Free Hand System. With free
motion quilting, it is of advantage to quilt from the center outwards and to guide the fabric using smooth,
round movements to form the design of your choice. Free motion quilting and darning are based on the
same free motion principles.
With stipple quilting, entire surfaces of the fabric are filled with quilt stitches. The single lines of stitching are
rounded and never cross one another.
Prerequisite:
• The top layer, the batting and the backing are pinned together or basted.
> Lower the feed dog.
> Attach the Free-motion Embroidery Foot (RX) to the presser foot holder bar.
– The pin (1) should rest on the upper side of the needle clamping screw (2).
> Press the Free-motion Embroidery Foot (RX) firmly from below with your index finger and tighten the
screw (3).
