(i) Note:

On delivery, all 4 threads are already threaded. You can begin sewing immediately. Should you wish to change the thread, and all 4 threads are still threaded, then proceed as described in the chapter "Changing threads (binding together)".

Should you need to rethread all threads from scratch, then proceed as described in this chapter, "Threading".

General instructions for threading

Attention!

Before threading, ALWAYS place the power switch ⑧ at "O" (Off) and remove the plug from the mains power socket. This prevents an unintended starting of the machine. If you do not, you run a risk of serious injury!

Correct threading is important, so that the stitches are not irregular and that the yarn does not break.

Behind the front flap 10 there is a diagram with instructions for threading. Additionally, the thread guides are marked in various colours.

In the accessory box you will find tweezers, the use of which helps make threading easier.

Threading is done in this order (Fig. 13/14):

1. First step: Upper looper (red)
2. Second step: Lower looper (yellow)
3. Third step: Thread for the right needle (green)
4. Fourth step: Thread for the left needle (blue)

(i) Note:

When all threads are threaded, and the lower looper thread loosens itself, proceed as follows:

• Unthread the two threads of the needles.
• Then thread the lower looper thread.
• First then rethread the threads of the two needles again.

The needles must always be the last to be threaded!

For simplification, the individual steps are numbered on the drawings.

Threading the upper looper thread (red)

Attention!

Before threading, ALWAYS place the power switch ⑧ at "O" (Off) and remove the plug from the mains power socket. This prevents an unintended starting of the machine. If you do not, you run a risk of serious injury!

Trial run

When yarn has been threaded for the first time, or after a yarn breakage it must be rethreaded, proceed as follows:

Lift the sewing foot 21.

Hold the ends of the threads between the fingertips of your left hand, slowly turn the handwheel ⑥ two or three times towards yourself and then check the threads once again.

Lay the material for a trial run under the sewing foot ② and slowly start to sew.

The material will be automatically fed through.

When the task is complete, continue sewing until an approximately 5cm (2") long length of threads has formed at the end of the material.

Cut through the threads with scissors.

Changing threads is quite simple with the following procedure:

1. Cut the yarn above the spool support ② (Fig. 34) and place the new roll of thread on the spool support ②.
2. Tie the ends of the new and the old thread together (Fig. 35).
3. Place the thread tension selector 14/15/16/17 at "0" (Fig. 36) and lift the sewing foot 21.
4. Pull on the other end of the yarn until the knot passes under the sewing foot 21.
5. For threading it in the needle, pull on the other end until the knot is in the eye of the needle and then cut the yarn to the left and right of the knot. Then carry out the rethreading.

Fig. 34 Fig. 35 Fig. 36

Set the stitch length

The stitch length can be adjusted from 1.0 to 4.0 mm. Almost all overlock work is carried out with a stitch length of 2.5 - 3.5 mm.

Turn on the adjustment wheel for stitch length ⑤ (Fig. 37) to adjust the stitch length:

• A stitch length of 3 mm is recommended for most sewing.
• For the working of heavy fabrics, a stitch length of 4 mm is to be recommended.
• For the working of light fabrics, a stitch length of 2 mm is to be recommended..

With these settings you will produce respectable seams and the fabric will not be crimped.

Setting the seam width

The width of seams can be determined both by changing the needle position and via the seam width adjustment knob 24.

... by using the right or left needle

The width of the seam can be determined by using the left or the right needle.

• Only the left needle is used: 5.7 mm
• Only the right needle is used: 3.5 mm

Fig. 37

... by turning the seam width adjustment knob

By using the seam width adjustment knob 24, seam width can be adjusted within the ranges indicated below.

• Only the left needle is used: 5.2 - 6.7 mm
• Only the right needle is used: 3.0 - 4.5 mm

Setting the seam width adjustment knob

Attention!

Before making adjustments with the seam width adjustment knob 24 always place the mains switch 8 at the position "O" (Off). This prevents an accidental start of the appliance and thus the risk of injury!

• Open the front flap 10, this can make the adjustment easier to carry out.
• Turn the seam width adjustment knob 24 to the desired seam width (Fig. 38). Orientate yourself on the scale on the stitch plate 13 (Fig. 39).

Adjust sewing foot pressure

Upon delivery, the sewing foot pressure is set for medium-weight materials. If you wish to use heavier or lighter materials, adjust the sewing foot pressure as follows:

• For lighter fabrics, you need to reduce the pressure.
• For heavier fabrics, you need to increase the pressure.

Insert the small screwdriver into the hole on the upper side of the machine (Fig. 40). The pressure adjustment screw is located here (A). Ensure that the screwdriver slips into the slot of the pressure adjustment screw (B) (Fig. 41).

• Turn the screwdriver in the direction "+" if you want to increase the pressure.
• Turn the screwdriver in the direction "-" if you want to reduce the pressure.

(i) Note:

To return to the factory-set default sewing foot pressure, turn the pressure adjustment screw as far as it will go anti-clockwise (-). Then turn it 6 rotations in a clockwise (+) direction.

The standard sewing foot pressure is reset.

Fig. 41

Manner of operation

The machine has two sets of toothed rack feeders, one to the front and one to the rear. Both sets move independent of each other. Through the differential feed motion both toothed rack sets can move themselves at various speeds.

With this, the fabric is stretched or gathered, depending on which transport differential has been set between the front and rear rack feeders.

With the aid of the differential transport, interesting effects can be achieved when sewing overlock seams on stretch materials and diagonally cut fabrics (Fig. 43).

(i) Note:

When the differential transport lever ⑨ stands at "1.0", that corresponds to a differential transport ratio of 1:1. Both toothed feed racks move at the same rate (Fig. 42).

The differential transport lever ⑨ can be adjusted in a range from 1:0.7 to 1:2.0.

0.2 1.0 2.0 Fig. 42 Fig. 43

Gathered overlock seam - Settings

The gathered overlock seam is suitable for the ruffling of sleeves, back upper parts, skirt seams etc. made of elastic materials such as knitwear and jersey. The individual parts should be brought together before sewing.

• Adjust the differential transport lever ⑨ to a value higher than 1.0 (Fig. 44). The exact setting depends on the material to be processed and the desired level of ruffling or gathering.
  Therefore always do a sample stitching to test the settings.

Stretched overlock seam - Settings

The stretched overlock seam is suitable for the manufacture of ruffles at the collar, cuffs and skirt edges etc. in soft, stretchy fabric and knitwear.

• Adjust the differential transport lever ⑨ to a value lower than 1.0 (Fig. 45). The exact setting depends on the material to be processed, and on the strength of the desired "ruffle effect".
  Therefore always do a sample stitching to test the settings.
• Hold the seam down with slight firmness before and behind the sewing foot 21 so as to keep the textile under tension.

(i) Note:

If you have set a value of "3" or higher on the adjustment wheel for the stitch length ⑤, this setting will automatically return to "3" when you set the differential transport lever ⑨ to 2.0.

Binding-off and sample sewing

• Lay all yarns under the sewing foot 21, to the rear, slightly to the left and over the stitch plate 13.
• Firmly hold the yarns under a slight tension.
• Turn the handwheel ⑥ 2 to 3 revolutions onto itself to begin empty chainstitch formation.
• Lower the sewing foot 21 with the sewing foot lever 4.
• Hold the empty chainstitch again firmly and carefully activate the foot pedal until the empty chainstatch is approximately 5 - 7.5 cm long.
• Place the fabric from the front under the sewing foot 21 and sew a test seam (Fig. 51). Under no circumstances should you pull on the textile, otherwise the needle will be bent or could even break off.
• Continue sewing even after the textile is finished for about 15 to 20 cm.
• Cut the empty chainstitch by using the blade at the rear of the machine (Fig. 52).

Recommended tension settings

i Note:

All information about tension settings for the different kinds of stitches are purely guiding values. The thread tension itself is always dependant on the type and thickness of the fabric, as well as needle strength and the strength, type and material composition of the yarn.

It is therefore absolutely necessary to sew a test seam. It is the only way you can find out if the tension settings are correct, or if they need to be changed.

With this machine you can sew four different roll hemming types. When sewing roll hemmings, the fabric edge is folded over and provided with an overlock seam. Lightweight fabrics such as batiste, chiffon, organza and so on are best for these kinds of seams. Heavy fabrics or stiff materials are not suitable for roll hemmings.

• Remove the left needle.
• Set the seam width switch 23 at "R" (Fig. 80).
• Align the support plate of the seam width finger on the marking "R" on the stitch plate by turning out the seam width adjustment knob 24 (Fig. 81).
• Place the dial for the stitch length ⑤ at "F - 2" (Fig. 82). With this a fine seam is sewn.
• For roll hemmings use a needle with specification Nr. 14.

i Tips:

• For a rolled hem many different combinations of yarn can be used. To create a particularly beautiful rolled hem (3-thread rolled hem), use a bushy yarn (bushy polyamid thread/woolly nylon) as the upper looper yarn and normal yarn for the needle and lower looper. For a 2-thread rolled hem use bushy yarn for the lower looper thread and normal yarn for the needle thread.
• At the start of sewing hold the empty thread chain firmly so that they cannot roll into the seam.
• Subject the material to slight tension in the sewing direction. This will make the seam more delicate.
• Before cutting the thread chain close to the textile, apply a small drop of fabric glue to the seam and allow it to dry. Check for colourfastness on the textile prior to this.

To produce flatlock seams, set up the thread tensions for a 3-thread overlock stitch. Sew a seam and then pull the fabric apart to smooth the seam.

The flatlock seam can be used as a decorative assembly seam or as pure ornamental stitching (Fig. 87, dark thread).

i Tips:

• Pay attention to proper tension, so that the workpiece can be pulled well apart after sewing.

• Use a decorative thread as the upper looper thread, since this is the most important thread and will be clearly visible.

• Remove the right or the left needle (Fig. 88).

• Set up the recommended tension settings for a 3-thread overlock seam (Fig. 89).

• Then readjust the upper thread tensions (green or blue) so that they are much looser.
• Now also release the thread tension of the upper looper (red) somewhat.
• Then adjust the thread tension of the lower looper (yellow) considerably tighter.

Flatlock seam as assembly seam

• Place the two fabrics to be sewn inside out to each other, so as to create a decorative seam on the front side.
• Sew the seam and while doing this cut away the excess fabric (Fig. 90).

Figure 91 shows you the stitch pattern for this stitch.

• The upper thread (needle thread) (green or blue) then has a V-shaped pattern on the inside of the fabric.
• The lower looper thread runs as a straight line along the fabric edge.
• Pull the fabric apart on both sides of the seam, so that the stitches lie flat.

Flatlock seam as decorative seam

• Adjust the movable upper blade 18 into a rest position (Fig. 92). The textile is not trimmed in this type of seam.

• Fold the textile so that the two inside sides lie on each other.

• Place the textile so that a portion of the stitch is sewn outside of the textile (Fig. 93).

• Sew the seam.
• Then fold the textiles apart. The stitches will then lie flat.

Overlock blind hems

The overlock blind hem is best suited for knitwear. It creates a durable edgetidying and is hardly noticeable (Fig. 94).

In one operation the protruding material is cut away, the hem is sewn and the edges are provided with an overlock seam.

1. Remove the left needle and set the machine up for a narrow 3-thread overlock seam.
2. Set the stitch length to 4 mm.
3. Fold the hem, first to the inside and then to the outside of the fabric, so that the fabric edge stands 6 mm above the first fold (Fig. 95).
4. Sew carefully on the fold. Thereby, the needle must pierce straight into the edge of the fold.

Pin tucks

To render your decorative garment as more creative, it can be provided with pin tucks before trimming (Fig. 96). Pin tucks are ornamental seams, as shown in the figure 96.

1. Remove the left needle and set the machine up for a narrow 3-thread over-lock seam.
2. Adjust the upper blade 18 into the rest position.
3. To achieve a uniform result, mark the desired number of pin-tucks on the fabric with water-soluble fabric pen or fabric chalk.
4. Fold the fabric inside out and sew it.
5. When all of the tucks are sewn, iron them all in one direction so that they lie evenly flat.

Outer corners

1. Cut away, before and after the corner, about 2 cm to the seam line (Fig. 97).

2. Sew a stitch further than to the marking "A" on the drawing and then stop (Fig. 97).

3. Lift the needle and sewing foot 21.

4. Pull the fabric to the rear, such that the yarn being held by the finger of the stitch plate 13 is released. (For better recognition, on the drawing opposite the sewing foot 21 is not shown - Figure 98).
5. Rotate the workpiece and lower the sewing foot 21 so that the upper blade 18 lies in a line with the cutting edge (Fig. 99).
6. Pull the loose threads up and continue to sew.

Inner corners

1. Cut the fabric away from the seam edge.

2. Adjust the upper blade 18 into the rest position (Fig. 100).

3. Sew on the cutting edge (Fig. 101).

4. Stop sewing just before reaching the corner.
5. Place a fold on the corner, so that the two edges form a line (Fig. 102).
6. Sew slowly over the corner and along the second edge. Ensure that you do not include the fold!

Using pins

Always insert pins to the left of the sewing foot 21 (Fig. 103).

The pins are thus not in the cutting area of the blade 18 22 and they can be easily removed afterwards.

⚠ Attention! Appliance Damage!

NEVER sew over pins or other hard materials. The blade 18 22 could be irreparably damaged!

Secure empty threads

To prevent the loosening of an empty thread chain, you should thread the empty thread chain into a hand-sewing needle. For security, insert the needle into the end of the seam.

Seam reinforcement

The seam can be strengthened if it is sewn with a reinforcing strip.

To do this, guide the strip through the slot in the front area of the sewing foot 21 (Fig. 104).

Place the strip under the foot and to the rear and then sew the seam. Thus the strip is sewn into the seam (Fig. 105).

Edging

1. Adjust the upper blade ⑱ into the rest position.
2. Remove the right needle and its thread.

3. Pull the cord inlay (yarn or reinforcing strip) through the slot in the front of the sewing foot 21 (Fig. 106).

4. Lay the cord inlay under the sewing foot 21 and chainstitch the desired length (Fig. 107).

You can use the chainstitched edgings individually or weave several together.
