INCLUDED ACCESSORIES 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.

Utility 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 ﬁ nger 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 this 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 right or left to sew closer to 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.

Sensor One-Step Buttonhole Foot

When connected to the machine, the buttonhole is sewn in a suitable length to the button size that has been entered into the machine.

Glide Sole

If sewing on foam, vinyl, plastic, or leather, the material might 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 soles to the underside of the presser foot.

Getting Ready to Sew – 11

LOWER THE FEED TEETH

The feed teeth are lowered when you move the switch on the front of the free arm to the right. Move the switch to the left 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.

PRESSER FOOT PRESSURE

Normal presser foot pressure is around ﬁ ve. The higher the number the more pressure the foot puts on the fabric. Knit and soft fabrics should be sewn at lower pressure.

The presser foot pressure is adjusted with the dial found under the lid. When adjusting the pressure lower the presser foot ﬁ rst.

RAISE AND LOWER THE PRESSER FOOT

The presser foot is raised and lowered with the presser foot lever (A). The presser foot must be lowered when sewing.

By raising the presser foot lever and then pressing it farther upwards, the lift height of the presser foot is increased to an extra height allowing you to slide very thick projects under the foot.

CHANGING THE PRESSER FOOT

Press the ON/OFF switch to OFF.

1. Make sure the needle is in the highest position and the presser foot is lifted. Pull the presser foot towards you.

2. Line up the cross pin on the foot with the gap in the presser foot ankle. Push back until the foot snaps into place.

12 – Getting Ready to Sew

CHANGING THE NEEDLE

Press the ON/OFF switch to OFF.

1. Loosen the screw in the needle clamp with the screwdriver.

2. Remove the needle.

3. Push the new needle upwards with the ﬂ at side away from you until it will go no further.

4. Use the screwdriver to tighten the screw properly.

NEEDLES

The sewing machine needle plays an important role in successful sewing. To ensure you will get a quality needle, we recommend needles of system 130/705H. The needle package included with your machine contains needles of the most frequently used sizes for sewing on woven and stretch fabrics.

A B

Universal needle (A)

Universal needles have a slightly rounded point and come in a variety of sizes. For general sewing in a variety of fabric types and weights.

Stretch needle (B)

Stretch needles have a special scarf to eliminate skipped stitches when there is a ﬂ ex in the fabric. For knits, swimwear, ﬂ eece, synthetic suedes and leathers. Marked with a yellow band.

Tip: Read more about different needles in the HUSQVARNA VIKING Accessory User’s Guide at www.husqvarnaviking.com.

Note: Change the needle often. Always use a straight needle with a sharp point (1). A damaged needle (2) can cause skipped stitches, breakage of needles or snapping of thread. A damaged needle can also damage the stitch plate.

Getting Ready to Sew – 13

SPOOL PINS AND SPOOL CAPS

Your sewing 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 in a horizontal position (the thread reels off the stationary spool) or in a vertical position (the thread spool rotates). Use the horizontal position for all regular sewing threads and the vertical position for large spools or specialty threads.

Horizontal Position

Lift the spool pin up slightly from its horizontal position to easily place the thread spool on the pin. The thread should reel over the top, in a counterclockwise direction, as shown in the picture. Slide on a spool cap and then move the spool pin back to the horizontal position.

Each machine comes with two spool caps on the spool pin. For medium sized thread spools, the medium sized cap (A) is placed in front of the spool. For large thread spools, the large cap (B) is placed in front of the spool.

The ﬂ at side of the spool cap should be pressed ﬁ r mly against the spool. There should be no space between spool cap and thread spool.

A small spool cap is included as an accessory for your machine. The small spool cap can be used for small thread spools.

Vertical Position

Lift the spool pin up and all the way to the right. Lock the spool pin in the vertical position by slightly pressing it down. Slide on the large spool cap. For spools smaller than the medium size spool cap or when using specialty threads, place a felt pad under the thread spool to prevent the thread from reeling off too fast. For larger spools, the felt pad is not needed.

Note: No spool cap should be placed on top of the spool as this prevents the spool from rotating.

Auxiliary Spool Pin

The auxiliary 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.

Lift the auxiliary spool pin up and to the left. Slide on a spool cap. For spools smaller than the medium size spool cap, place a felt pad under the thread spool to prevent the thread from reeling off too fast. For larger spools, the felt pad shall not be used.

14 – Getting Ready to Sew

THREADING THE UPPER THREAD

Make sure the presser foot is raised and the needle is in the up position

Press the ON/OFF switch to OFF.

1. Place the thread on the spool pin and the spool cap on the spool pin as described on page 14.

2. Spool pin in horizontal position: Bring the thread over and behind the pre-tension thread guide (A) and under the thread guide (B).

Spool pin in vertical position:

Instead of bringing the thread into the pre-tension guide (A), bring it directly under the thread guide (B).

3. Bring the thread down between the thread tension discs (C).

4. Continue threading in the direction indicated by the arrows. Bring the thread from the right into the slot on the take-up lever (D).

5. Take the thread down and behind the last guide just above the needle (E).

Getting Ready to Sew – 15

NEEDLE THREADER

The needle must be in the up position to use the built-in needle threader. We also recommend lowering the presser foot.

1. Use the handle to pull the needle threader all the way down, catching the thread under the guide (A).

2. Push back to bring the needle threader forward until the metal ﬂ anges cover the needle. A small hook will pass through the needle eye (B).

3. Place the thread under the ﬂ anges in front of the needle, so the thread catches into the small hook (C).

4. Let the needle threader gently swing back. The hook pulls the thread through the needle eye and forms a loop behind the needle.

5. Pull the thread loop out behind the needle. Place the thread under the presser foot.

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, the wing needle, twin needle, triple needle or when the Sensor One-Step Buttonhole Foot is on. There are also some other optional accessories that require manual threading of the needle.

1. 2.

When threading the needle manually, make sure that the needle is threaded from front to back. The white presser foot ankle makes it easy to see the eye of the needle. The bobbin case cover can be used as a magnifying glass.

CUTTING THE THREAD

Once you have ﬁ nished 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 – Getting Ready to Sew

THREADING FOR TWIN NEEDLE

Press the ON/OFF switch to OFF.

1. Insert a twin needle.

2. Use a second thread spool or wind a bobbin with the thread you are going to use as the second upper thread.

3. Lift the spool pin up and all the way to the right. Lock the spool pin in the vertical position by slightly pressing it down. Slide on a spool cap. For spools smaller than the medium size spool cap, place a felt pad under the thread spool.

4. Place the ﬁ rst thread spool on the spool pin. The spool should rotate in a clockwise direction when the thread reels off the spool.

5. Left needle: Thread the machine as described on page 13. Check to ensure that the thread lies between the left thread tension discs (A). Thread the left needle manually.

Note: Only use symmetrical twin needles (C). Do not use this type of twin needle (D), since it may damage your sewing machine.

6. Pull out the auxiliary spool pin and slide on a spool cap. For spools smaller than the medium size spool cap, place a felt pad under the thread spool.

7. Place the second thread on the spool pin. The second spool should rotate in a counterclockwise direction when the thread reels off the spool.

8. Right needle: Thread the machine as before but this thread should lie between the right thread tension discs (A) and outside the needle thread guide (B). Thread the right needle manually.

Note: If using specialty threads (such as metallic threads) its weight and irreglular surface increases the thread tension. By reducing the tension, the risk of needle breakage is prevented.

Getting Ready to Sew – 17

WINDING THE BOBBIN 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 an empty bobbin on the bobbin spindle on the top of the machine. The bobbin only ﬁ ts on one way, with the logo facing up. Use only original HUSQVARNA VIKING

2. Pull the thread from the needle under the presser foot and to the right through the thread guide (C).

3. Guide the thread through the hole in the bobbin (D) from the inside to the outside.

THREAD TENSION, 650

Use the recommended top thread tension setting given on the GraphicDisplay. You might need to adjust the top thread tension for special threads, fabrics and/or techniques. To set the tension, turn the numbered tension dial. The higher the number the tighter the tension.

Normal top thread tension is set to 4-6. When sewing buttonholes and decorative stitches set thread tension to around 3. When topstitching with a heavy weight thread in thick fabric, increase the tension to 7-9. Thread tension recommendation is always given on the GraphicDisplay for the selected stitch and fabric.

Make a few tests on a scrap piece of the fabric you are going to sew and check the tension.

AUT OMATIC THREAD TENSION, 670

The 670 model automatically sets the best thread tension for the selected stitch and fabric. The thread tension can be adjusted for specialty thread, techniques or fabric. Touch + to increase the thread tension and - to decrease it.

Correct and Incorrect Thread Tension

To understand the correct thread tension, sew a few sample straight stitches at different settings.

1. Begin with a tension that is too loose, i.e. set at the lowest number. The bobbin thread will lie straight and the top thread will be drawn to the underside of the fabric.

2. If you set the tension at the highest number, the bobbin thread will be visible on the top side of the fabric. The seam may pucker and the top thread might break.

3. The correct thread tension is set when the threads interlock in between both fabric layers or, in the case of decorative stitches, on the underside.

ST ARTING TO SEW

A straight stitch is selected by default when you turn on the machine. Before starting to sew, select your fabric quality in the Exclusive SEWING ADVISOR™ feature, and set yout machine according to the recommendations on the GraphicDisplay/ TouchScreen (page 46).

To start sewing, place top and bobbin thread under the presser foot and to the back. For best results when beginning at the edge of the fabric, place a ﬁ nger on the threads to hold them in place as you begin.

Place fabric in position under the presser foot. Lower the presser foot and step on the foot control to begin sewing. Guide the fabric gently with your hands as the machine is feeding.

See page 26 (650)/35 (670) for reference on how to select another stitch or how to use the Exclusive SEWING ADVISOR™ feature (page 46).
