Directions for use

These service instructions are intended to be used by service workshop personnel, or by
salesmen who carry out servicing their own districts. They assume a thorough knowledge
of the handling of precision appliances and accessibility to service tools.
The manual is divided into two sections and covers all service operations and checks
which should be carried out when making a complete overhaul of a sewing machine.
The first section deals with the various settings which must be maintained to ensure that
the machine functions satisfactorily .
The second section covers dismantling and mounting instructions.
The diagrams only give indication as to where the detail or mechanism is located in
the machine. For more detailed information regarding the construction, etc., refer to
the diagrams in the spare parts list.

ESD

A TTENTION!

It is of the utmost importance that precautions are being taken in order to avoid damage
of the electronics by electro static discharges ESD (=Electro S tatic Discharge). To avoid
that these errors arise it is important to handle loose circuit boards in a controlled way .

Always use wrist band 412 23 02-01 when servicing.

Service tools

A reasonable requirement in a domestic sewing machine is that it should able to sew all
types of fabrics used in the home. The settings made when assembling and sewing-in
the machines are those most suited to give the best results in the majority of fabrics and
fabric combinations. In doing so, consideration has been given to the requirements of
different markets. This does, however , mean that when sewing extreme fabrics, better
results may be obtained in certain cases by altering the settings. It must be pointed out
that these altered settings can cause poorer results on more normal fabrics. How
the different standard ratings are set can be seen from the description under each
setting instruction. The following list of setting gauges and service tools is intended as
an instruction about the special service tools needed to servicing this machine.

1. On several different occasions the needle is
used as a setting gauge.
The setting ratings are adapted to needle 90.
Make sure to use an undamaged needle.

2. Gauge for setting the timing of the hook in
relation to the needle .

How to synchronize the touch area of the touch panel with the symbols on the screen.
Get into the service program of the machine.

Press the needle stop button or touch Touch ,row 1 on the service card.

1. Touch with a blunt object in the center of cross 1 so that it disapeares. Indicated as the First

calibration mark on the illustration.

2. Touch with a blunt object in the center of cross 2, indicated Second calibration mark

on the illustration.NOTE ! The second calibration mark is the red cross on the Service card.

3. Touch the 3rd cross and the machine will return to Service menu or the menu that was open before the

Calibration is done . NOTE! The Third calibration mark will only appear in the display when the

second calibration mark is calibrated.

Update of the memory - Quilt Designer (Read & write unit)

The Quilt Designer has a memory in which the characteristics and stitches of the machine are stored.
In order to update the memory the machine has an update mode.
The program memory on Quilt Designer is updated through the Programmable d-Card.

Revision of the program

The revision of the program can be seen in the middle of the welcome screen or checked in the service
program menu 1.

How to transfer the Quilt Designer program memory to a programmable d-Card

A d-Card reader/writer is needed to transfer the program memory to programable d-Card.
The latest version of the Quilt Designer program memory can be found on Husqvarna Vikings Internet page.

NOTE! All data that is stored on the programmable d-Card will be erased when the Quilt Designer
program memory is transfered to the programmable d-Card.

Make sure that the d-card reader/writer is properly connected to the computer before starting the download.

1. Insert a programmable d-Card in the d-Card reader/writer unit.

2. Go to the Husqvarna Viking update page on the Internet. Click on the Quilt Designer update icon.

3. A update program will st art. Follow the instructions in the program.

4. Remove the Programmable d-Card when the update files are transfered to it.

How to update the machine

1. Insert the programmable d-Card with the new memory
information in the d-Card reader in the machine.

2. Get into the update mode of the machine
by pressing the presser foot down button
and the stitch re-start button while
the main switch (A) is turned on.

3. The memory will now automatically
be updated.

4. When the memory of the machine is correctly
updated REST ART is indicated on the screen.
Then...

-Turn off the machine.

-Remove the d-Card.

Press

5. Re-start the machine and check the revision (see above).

NOTE! If the Main PC board is changed the memory always has to be updated with the latest
version.
