5. Push the power switch to "O" to turn off the machine.

Note: When the front cover is open the safety switch is activated and prevents the machine from sewing, even if the foot control is pressed.

Note: Your machine is adjusted to provide the best stitch result at normal room temperature. Extreme hot and cold temperatures can affect the sewn result.

Setting Up the Telescopic Thread Stand

Extend the telescopic thread stand to its full height, then turn until it clicks into place.

Place the thread spools or cones over the cone holders on the spool pin.

If the machine is already threaded, straighten the threads to prevent tangling.

Open and Close the Front Cover

Open the Front Cover

First push the cover to the right as far as it will go and then pull it downward toward you.

Close the Front Cover

First pull the cover upward and then slide it to the left until it locks.

Note: The front cover has a safety switch and the machine will no sew if the front cover is open.

Remove and Replace the Flat Bed Extension

Free Arm Sewing

For free arm sewing, slide off the flat bed extension. The free arm makes it easier to sew small items and hard to reach areas such as armholes and overcasting trouser cuffs.

Remove the Flat Bed Extension

Insert a finger in the slot on the left side of the flat bed extension. Slide the flat bed extension to the left and remove it from the machine.

Replace the Flat Bed Extension

Align the projections on the flat bed extension with the grooves on the free arm and slide it to the right until it snaps into place.

Presser Foot Lifter

Raise the presser foot with the presser foot lifter (A) at the back of the machine.

Changing the Needles

Turn off the main power switch and unplug the machine.

1. Turn the hand wheel toward you until the needles are at the highest position.
2. Loosen, but do not remove the left (B) and/or right (A) needle clamp screw with the allen key while you are holding the needles.
3. Remove the left or right needle, depending on the stitch type you want to sew.
4. Hold the new needle(s) with the flat surface to the back.
5. Insert the needle(s) into the left and/or right needle clamp as far as it/they will go.
6. Securely tighten the left (B) and/or right (A) needle clamp screw.

Note: When using both needles, the left needle is positioned a little higher up than the right needle (they are not supposed to be 'level', like a twin needle).

Changing the Presser Foot

Turn off the main power switch and unplug the machine.

1. Raise the presser foot.
2. Turn the hand wheel toward you until the needles are in the highest position.
3. Push the black button on the back of the presser foot holder (A), and the foot will come off.
4. Place the new foot with the pin (B) right underneath the groove of the ankle and lower the presser foot. Push the black button on the back of the presser foot bar (A) and the foot will snap into place.

Note: Optional feet are not included.

Deactivate the Upper Cutter

• Turn the hand wheel toward you until the upper cutter is in its lowest position.
• Turn off the upper cutter by switching the upper cutter switch to non-cutting position (A).

Reactivate the Upper Cutter

• Turn on the upper cutter by switching the upper cutter switch to cutting position (B).

Note: Always have the upper cutter in the cutting position when sewing, because this machine must trim off any excess fabric to form the stitch over the fabric edge. An exception to this is when sewing decorative flatlock seams. Then the upper cutter needs to be turned off.

Attach the 2-thread Overlock Converter

2-thread overlock stitches are sewn using one needle thread and the lower looper thread. Before sewing, the two-thread converter must be attached to the upper looper, so the machine will sew with only two threads.

1. Open the front cover.
2. Bring the upper looper to its lowest position by turning the hand wheel toward you.
3. Insert the tip of the converter (A) into the hole of the upper looper (B).
4. Push the converter (C) down into the slot of the upper looper.

Remove the 2-thread Overlock Converter

Remove the converter by tilting it toward you (D).

Lower looper thread

Correct Thread Tension

Lower looper thread and upper looper thread should be well balanced with the same tension (both looper threads should cross at the edge of the fabrics). Needle threads should not be too loose or too tight, but equally balanced tension.

Upper Looper Thread Is Too Loose (A)

The upper looper thread is unbalanced when it is pulled to the wrong side of the fabric. Tighten the thread tension of the upper looper or loosen the thread tension of the lower looper.

Upper Looper Thread is Too Tight (B)

The upper looper thread is unbalanced when it is pulling on the top side of the fabric. Loosen the thread tension of the upper looper or tighten the thread tension of the lower looper.

Lower Looper Thread is Too Loose (C)

The lower looper thread is unbalanced when it is pulled to the right side of the fabric. Tighten the thread tension of the lower looper or loosen the thread tension of the upper looper.

Lower Looper Thread is Too Tight (D)

The lower looper thread is unbalanced when it is pulling on the wrong side of the fabric. Loosen the thread tension of the lower looper or tighten the thread tension of the upper looper.

Left Needle Thread Is Too Loose (E)

If the left needle thread is too loose, tighten the thread tension of the left needle or loosen both looper threads.

Left Needle Thread is Too Tight (F)

If the left needle thread is too tight, loosen the thread tension of the left needle.

Right Needle Thread is Too Loose (G)

If the right needle thread is too loose, tighten the thread tension of the right needle.

Right Needle Thread is Too Tight (H)

If the right needle thread is too tight, loosen the thread tension of the right needle.

Differential Feed Adjustment

The differential feed system consists of two sets of feed teeth arranged one behind the other (A). Both feed teeth work independently of each other to provide good results when sewing on speciality fabrics. When the amount of feed by the front feed teeth is changed in relation to the feed by the rear feed teeth it will "stretch" or "gather" the fabric.

Use the differential feed to prevent stretching or distortion of knit fabrics and puckering of lightweight fabrics.

For overlock stitching on normal fabric, set the differential feed to 1.0 (B).

Gathered Overlock (C)(Stretch, Knit Fabrics)

When overedging stretch fabric, such as knits and jersey, adjust the differential feed to a number between 1.0 and 2.0. The setting depends on the fabric being sewn. Test sew with different settings before sewing on your project.

Stretch Overlock (D)(Light Weight Fabrics)

When overedging light woven or loosely knit fabrics, such as silk and silky knitwear, adjust the differential feed to a number between 0.7 and 1.0. When sewing, apply gentle tension to the fabric by holding the seam lightly in front and back of the presser foot. The setting depends on the fabric being sewn as well as the desired amount of stretching. Therefore, test sew with different settings before sewing on your project.

Fabric Differential Feed Adjustment Result
Stretch fabric (knit, jersey)		1.0-2.0
Non-stretch fabric (cotton, denim)		1.0
Light-weight fabric (Silk, silky knitwear)		0.7-1.0

Presser Foot Pressure Adjustment

The presser foot pressure is pre-set for sewing on medium weight fabric. When sewing in different fabric weights, adjustment might be needed. Generally, decrease the presser foot pressure when sewing in light weight fabric and increase it when sewing in heavy weight fabrics. Always test sew on a sample of your fabric before sewing on your project.

Increase or decrease the pressure in small increments by turning the presser foot pressure screw.

Less pressure: Decrease the pressure by turning the adjustment knob in counter-clockwise direction towards the "-".

More pressure: Increase the pressure by turning the adjustment knob in clockwise direction towards the "+"

Back to standard setting: Turn the adjustment knob until the distance from the front cover to the "head" of the screw is 10mm (3/8").

Stitch Width Settings

The stitch width can be increased or decreased by changing the needle position or with the cutting width lever.

Width Adjustment by Changing Needle Position

A) When only the left needle, or when both needles are used the stitch width is approx. 6mm (1/4^ )

B) When only the right needle is used the stitch width is approx. 3mm(%) .

Width Adjustment with the Cutting Width Lever

By fine tuning the cutting width, using the cutting width lever, adjustments are possible within the range shown below:

When only the left needle is used: 5 - 7mm

When only the right needle is used: 3 - 5mm

Move the lever up and down to adjust the stitch width, "7" is the widest and "1" is the most narrow setting.

Stitch Length Settings

The stitch length dial should be set to "3" for most sewing. Adjust the stitch length to 4mm when sewing on heavy weight fabrics. Adjust the stitch length to 2mm when sewing on light weight fabrics.

Stitch Finger Lever Setting

The stitch finger lever should be set to "N" (Normal) for all standard overlock sewing. To sew rolled edge you need to retract the stitch finger by setting the stitch finger lever to "R" (Rolled Edge). When moving the stitch finger, be sure to push the lever as far as it will go in each direction.

SEWING

On your overlock machine, different stitches are obtained by combining different needle positions, threading methods, tension settings, and the use of the 2-thread overlock converter.

See Getting Ready to Sew, page 7, for references on how to set your machine.

Stitch Overview

The settings shown in the table below are our recommendations based on normal conditions. It may be necessary to adjust the thread tension depending on the stitch, type of fabric and thread you are using. For best results make tension adjustments in small increments of no greater than half a number at a time. Always test sew on a sample of your fabric before sewing on your project.

In the table below, different fabric weights and types are explained. For you to better understand how the stitches are formed, each of the threads are displayed in different shades of grey.

Changing Thread

The following is an easy way to change threads:

1. Cut the thread in near the spool, behind the guides on the telescopic thread stand.
2. Remove the thread spool and place the new thread on the spool pin.
3. Tie the end of the new thread to the end of the old thread. Cut the thread tails to 2-3cm (approx. 1^ ) in length and firmly pull both threads to test knot security.
4. Raise the presser foot.
5. First note tension dial settings and then turn the tension dials down to "0".
6. Pull the threads through the machine one at a time until the knots are in front of the needle. If the threads do not pull easily, check for tangles on thread guides or looping under thread stand.
7. Cut the thread behind the knot and thread the needle.
8. Return tension dials to previous settings.

Start Sewing

1. When the machine is completely threaded, close the front cover and bring all of the threads over the stitch plate and slightly to the left under the presser foot.
2. Ensure that the upper blade moves against the lower blade correctly by turning the hand wheel slowly toward you. If the upper cutter blade does not move correctly, check if there are any fabric or waste thread stuck between the blades.
3. Hold the threads and apply a slight tension.
4. Turn the hand wheel toward you 2 or 3 complete turns to start making a thread chain. Check if all threads wind around the stitch finger of the stitch plate. If the threads do not wind around the finger, make sure each thread is threaded correctly.
5. Continue holding the thread chain while pressing the foot control. Sew until the chain is 5-8cm (2^ - 3^ ) in length.
6. Place fabric under the front of the presser foot and sew a test sample. Guide the fabric slightly with your left hand while sewing. Do not pull on the fabric as this may deflect the needle, causing it to break.
7. When you reach the end of the fabric, continue sewing while drawing the finished fabric gently backwards and to the left. This is called chaining off. It prevents the threads from coming undone and prepares for next sewing.
8. Cut off the thread chain 2-5cm (1"-2") behind the presser foot.

Pin Placement

Insert straight pins to the left of the presser foot. The pins will be easy to remove and are away from the cutters.

Warning: Sewing over pins will damage and might destroy the edge of the cutters.

Securing Thread Chain

1. Thread the chain into a large eyed, hand sewing needle.
2. Insert the needle into the end of the seam and pull the chain into the seam to secure the threads.

Cored Overlock

Cored overlock can be used to strengthen stitches when joining elastic fabrics such as knits. Cording prevents knit fabrics from stretching and also stabilizes the seams.

1. Insert the cord through the hole in the front of the foot.
2. Position the cord under the foot to the back of the machine and sew the garment seam.
3. The cord is attached in the stitch as the seam is sewn.

Gathering Using the Differential Feed

The differential feed can be used to gather lightweight fabrics. Use it for sleeves, making ruffles, and more.

Set the differential feed between 1.5 and 2 to obtain the best gathering effect for your project. Always try on a scrap piece of your fabric first. See Differential Feed Adjustment, page 12, to learn how to adjust the differential feed.

Rolled Edge Sewing

The rolled edge stitch is appropriate for light weight fabrics such as lawn, voile, organdy, crepe, etc. The rolled edge is achieved by adjusting the thread tension to make the fabric edge roll under the fabric while overlocking. Adjust the thread tension to change the degree of rolling. To sew rolled edge you need to set the stitch finger lever to "R".

Tip: For a beautiful rolled edge, thread the upper looper with a decorative thread and the needle and lower looper with lightweight regular thread

2-Thread Rolled Edge (A)

1. Attach the 2-thread overlock converter (see page 6).
2. Use the right needle thread and lower looper thread.
3. Move the stitch finger lever to "R".
4. Set the stitch length dial to "1" for a fine seam.
5. Set the thread tension according to the stitch table on page 18.
6. Make a thread chain and test sew on a sample of your fabric before sewing on your project. Hold the thread chain while beginning to sew to keep it from curling into the seam.

A variant of the rolled edge stitch (B) is the narrow edge (C). It can be obtained by adjusting the thread tension according to "3-Thread Rolled Edge" (page 17) and/or "3-Thread Narrow Edge" (page 16).

1. Use the right needle thread and the upper and lower looper threads.
2. Move the stitch finger lever to "R".
3. Set the stitch length dial to "3-2" for a fine seam.
4. Set the thread tension according to "3-Thread Rolled Edge" (page 17) or "3-Thread Narrow Edge" (page 16).
5. Make a thread chain and test sew on a sample of your fabric before sewing on your project. Hold the thread chain while beginning to sew to keep it from curling into the seam.

Flatlock Sewing

A Flatlock (A) is made by adjusting the tension of the 3-thread overlock stitch, sewing the seam and pulling the fabrics apart to flatten the seam. The tensions must be adjusted correctly for the fabric to pull flat properly.

A Flatlock can be used both as a decorative construction stitch, sewing two pieces together (Standard Flatlock), or for decoration only on one piece of fabric (Decorative Flatlock).

There are two ways to sew a Flatlock. Either with the wrong sides of the fabric together to create a decorative look, or with the right sides together, to create a Ladder Stitch.

Standard Flatlock, Wide (B)

1. Use the left needle.
2. Thread the lower and upper looper and the left needle.
3. Set the thread tension according to "3-Thread Flatlock, Wide (and Narrow)" on page 16.
4. Place the wrong sides of the two pieces of fabric together to sew a decorative stitch on the right side of the project.
5. Sew the seam, trimming the excess fabric. The needle thread will form a V on the underside of the fabric. The lower looper thread will pull into a straight line at the fabric edge.
6. Unfold the fabric and pull on opposite sides of the seam to pull the stitches flat.

Decorative Flatlock, Wide (C)

1. Place the upper cutter in the nonworking position (page 6). The fabric should not be trimmed on this stitch.
2. Follow steps 1-3 above.
3. Fold the fabric piece, wrong sides together, to sew a decorative stitch on the right side of the project.
4. Position the fabric so the seam is sewn with part of the stitch extending off the fabric.
5. Unfold the fabric and pull on opposite sides of the stitch to flatten.

Tip: The upper looper thread is the prominent thread in the flatlock stitch. Place a decorative thread in the upper looper and regular threads in the lower looper and needle.

LadderStitch (D)

A ladder stitch is a flatlock stitch but sewn with the right sides of the fabric together. The needle thread will be the prominent thread that creates the ladder.

MACHINE MAINTENANCE

An overlock requires more frequent maintenance than a conventional sewing machine for two reasons:

• A lot of lint is produced when the cutters are cutting the fabric.
  An overlock runs at a very high speed and needs to be oiled frequently to lubricate the internal working parts.

Cleaning

Turn off the main power switch and unplug the machine.

Open the front cover and remove all the lint using a lint brush.

Oiling

Turn off the main power switch and unplug the machine.

To keep the machine running smoothly and quietly the moving parts, pointed out in the picture, must be lubricated often. We recommend lubricating after every 24 hours of use.

Use sewing machine oil. Do not use any other oil, it could damage the machine.

Wipe the machine surface to remove all excess oil before sewing.

Replacing the Lower Cutter

Turn off the main power switch and unplug the machine.

The stationary lower cutter should be changed when it becomes blunt. Change it by following the below instructions. If you are having any difficulties, consult your service agent to make the necessary adjustments.

• Turn off the upper cutter (A). Open the front cover.
• Loosen the lower cutter set screw (B) and remove the stationary cutter (C).
• Place a new lower cutter in the groove of the lower cutter holder. The blade of the lower cutter shall be flush with the stitch plate.
• Tighten the lower cutter set screw (B).
• Turn the upper cutter (D) on again.
• Turn the hand wheel so the needles are in their lowest position.

Replacing the Upper Cutter

Turn off the main power switch and unplug the machine.

The upper cutter should be changed when it becomes blunt. Change it by following the below instructions. If you are having any difficulties, consult your service agent to make the necessary adjustments.

• Place the upper cutter in its lowest position.
• Turn off the upper cutter (A). Open the front cover.
• Loosen the upper cutter set screw (B) and remove the upper cutter (C).
• Place a new upper cutter in the groove of the upper cutter holder. The front edge of the upper cutter is approx 0,2-0,5mm lower than the cutting edge of the stationary cutter (D).
• Tighten the upper cutter set screw (B).
• Turn the upper cutter (E) on again.

Storage

When the machine is not in use, be sure to keep it unplugged. Store the machine, so it is not exposed to direct sunlight or humidity.
