Note: Always have the cutter down in the cutting position when sewing, because this machine must trim off any excess fabric to form the stitch over the fabric edge.
(Diagram description: Diagrams show the movable upper cutter being moved to the nonworking position (A) and back to the cutting position.)
Attaching 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.
- Open the front cover.
- Bring the upper looper to its lowest position by turning the handwheel toward you.
- Insert the pin (A) of the converter in the hole (B) of the upper looper.
- Put the positioning rib (C) in contact with the upper edge of the looper.
- Insert the point (D) in the hole of the upper looper.
Removing the 2-thread overlock converter:
- Remove the point (D) from the hole of the upper looper and remove the converter.
- Put the 2-thread converter back to the accessory storage.
(Diagram description: Diagrams show the 2-thread converter being attached to the upper looper using pins A, B, and D, and positioning rib C.)
Threading the Machine
A color-coded diagram is located inside the front cover for quick reference. When threading the machine, thread only in the following order:
- Upper looper threading - Purple
- Lower looper threading - Yellow
- Right needle threading - Green
- Left needle threading - Blue
Important: If the lower looper should come unthreaded, do the following:
- Unthread the needle(s)
- Thread the lower looper
- Thread the needle(s)
(Diagram description: A diagram shows the upper part of the machine with the four thread paths indicated by numbers 1-4 and colors purple, yellow, green, and blue.)
Threading the Upper Looper (Purple)

- Raise the presser foot and place the thread to the back, under the presser foot.
(Diagram description: A series of diagrams illustrate the step-by-step process of threading the left needle, referencing numbered guides and parts, including the specific path through guide (5).)
Changing Thread
The following is an easy way to change threads:
- Cut the thread in use near the spool, behind the guides on the telescopic thread stand.
- Remove the thread spool and place the new thread on the spool pin.
- Tie the end of the new thread to the end of the old thread. Cut the thread tails to 2-3 cm in length and firmly pull both threads to test knot security.
- Raise the presser foot.
- First note tension dial settings and then turn the tension dials down to "0".
- 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.
- Cut the thread behind the knot and thread the needle.
- Return tension dials to previous settings.
Note: When using standard thread spools, place the thread unreeling disc as shown to prevent the thread from getting caught on the edge of the spool.
(Diagram description: Diagrams show the thread stand with multiple threads, the needle area during thread change, and the use of an unreeling disc.)
Start Sewing
- 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.
- Ensure that the upper blade moves against the lower blade correctly by turning the handwheel slowly toward you. If the blades are not moving correctly, check if there are any fabric or waste thread stuck between the blades.
- Hold the threads and apply a slight tension.
- 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.
- Continue holding the thread chain while pressing the foot control. Sew until the chain is 5-8 cm in length.
- 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.
- 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.
- Cut off the thread chain 2-5 cm behind the presser foot using the thread cutter on the left side of the machine. Pull the threads around the thread cutter from the back, then toward you.
(Diagram description: Diagrams show the formation of a thread chain, the process of chaining off, and the use of the thread cutter.)
Thread Tension Settings
Set the thread tension to suit the type of fabric and thread used. As the number on the thread tension discs increases, the thread tension becomes tighter.
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.
See the stitch table on pages 23-26 for thread tension recommendations for each stitch.
When the upper looper thread is too loose
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 (purple) or loosen the thread tension of the lower looper (yellow).
When the lower looper thread is too loose
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 (yellow) or loosen the thread tension of the upper looper (purple).
When the left needle thread is too loose
The left needle thread is too loose, tighten the thread tension of the left needle (blue) or loosen both looper threads (purple and yellow).
When the right needle thread is too loose
The right needle thread is too loose, tighten the thread tension of the right needle (green).
(Diagram description: Diagrams show the right and wrong sides of fabric illustrating how unbalanced thread tensions cause threads to pull to one side.)
Differential Feed Adjustment
The differential feed system consists of two sets of feed teeth arranged one behind the other. Both feed teeth work independently of each other to give perfect 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 of knit fabrics and puckering of lightweight fabrics.
For overlock stitching on normal fabric, set the differential feed adjusting lever to 1.0.
Gathered Overlock (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 (Lightweight 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 material being sewn as well as the wished amount of stretching. Therefore, test sew with different settings before sewing on your garment.
Fabric | Differential Feed 1.0 | Adjustment | Result |
---|---|---|---|
Stretch fabric (Knit, jersey) | 1.0 - 2.0 | (Diagram description: Shows fabric gathered.) | |
Non-stretch fabric (Chino, denim) | 1.0 | 1.0 | (Diagram description: Shows fabric with a normal stitch.) |
Lightweight fabric (Silk, silky knitwear) | 0.7 - 1.0 | (Diagram description: Shows fabric stretched.) |
(Diagram description: A diagram shows the differential feed adjusting lever.)
Presser Foot Pressure Adjustment
The presser foot pressure is pre-set for sewing based on normal conditions. Adjustment might be necessary in some conditions. Increase or decrease the pressure until you are satisfied with the result. Always test sew on a sample of your fabric before sewing on your garment.
Less pressure: Decrease the pressure by turning the adjustment tool in counter-clockwise direction.
More pressure: Increase the pressure by turning the adjustment tool in clockwise direction.
(Diagram description: A diagram shows the adjustment screw for presser foot pressure and indicates clockwise/counter-clockwise rotation.)
Stitch Width Settings
The stitch width can be increased or decreased by changing the needle position or with the width adjustment knob.
Width adjustment by changing needle position
A) When only the left needle, or when both needles are used, the stitch width is 5.7 mm.
B) When only the right needle is used, the stitch width is 3.5 mm.
Width adjustment with the width adjustment knob
By fine tuning the cutting width, using the width adjustment knob, further adjustments are possible within the range shown below:
A) When only the left needle is used: 5.2 - 6.7 mm
B) When only the right needle is used: 3.0 - 4.5 mm
Turn the knob to adjust the desired seam width, using the graduations on the stitch plates as a guideline.
(Diagram description: Diagrams show stitch width examples for left and right needles (5.7mm and 3.5mm) and a close-up of the width adjustment knob with markings.)
Stitch Length Settings
The stitch length dial should be set on "3" for most sewing. Adjust the stitch length to 4 mm when sewing on heavy weight fabrics. Adjust the stitch length to 2 mm when sewing on light weight fabrics.
Stitch Finger Lever Setting
The stitch finger lever should be set to "S" for all standard overlock sewing. To sew rolled edge, you need to retract the stitch finger by setting the stitch finger lever to "R". When moving the stitch finger, be sure to push the lever as far as it will go in each direction.
(Diagram description: Diagrams show the stitch finger lever in the 'S' and 'R' positions.)
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". The minimum overlock stitch width that can be obtained for rolled edging is approximately 1.5 mm since the cutting width cannot be set below 3.5 mm.
A variant of the rolled edge stitch is the narrow edge. It can be obtained by adjusting the thread tension according to the stitch table on pages 23-26.
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 / Narrow Edge
- Attach the 2-thread overlock converter (see page 8).
- Use the right needle thread and lower looper thread.
- Move the stitch finger lever to "R".
- Set the stitch length dial to "3-2" for a fine seam.
- Set the thread tension according to the stitch table on pages 23-26.
- Make a thread chain and test sew on a sample of your fabric before sewing on your garment. Hold the thread chain while beginning to sew to keep it from curling into the seam.
3-Thread Rolled Edge / Narrow Edge
- Use the right needle thread and the upper and lower looper threads.
- Move the stitch finger lever to "R".
- Set the stitch length dial to "3-2" for a fine seam.
- Set the thread tension according to the stitch table on pages 23-26.
- Make a thread chain and test sew on a sample of your fabric before sewing on your garment. Hold the thread chain while beginning to sew to keep it from curling into the seam.
(Diagram description: Diagrams show examples of 2-thread and 3-thread rolled edges and narrow edges.)
Flatlock Sewing
A Flatlock Stitch is made by adjusting the tension of the 2- or 3-thread overlock stitch, sewing the seam and pulling the fabric apart to flatten the seam. The tensions must be adjusted correctly for the fabric to pull flat.
The Flatlock Stitch can be used both as a decorative construction stitch, sewing two pieces together (Standard Flatlock Stitch), or for ornamentation only on one piece of fabric (Ornamental Flatlock Stitch).
There are two ways to sew a Flatlock Stitch: 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 Stitch
- Use the left needle.
- For 2-thread Flatlock: Attach the 2-thread converter (see page 8). Thread the lower looper and the left needle.
- For 3-thread Flatlock: Thread the lower and upper looper and the left needle.
- Set the thread tension according to the stitch table on pages 23-26.
- Place the wrong sides of the two pieces of fabric together to sew a decorative stitch on the right side of the garment.
- 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.
- Unfold the fabric and pull on opposite sides of the seam to pull the stitches flat.
Ornamental Flatlock Stitch
- Place the movable upper cutter in the nonworking position. The fabric should not be trimmed on this stitch.
- Follow steps 1-3 above.
- Fold the fabric piece, wrong sides together, to sew a decorative stitch on the right side of the garment.
- Position the fabric so the seam is sewn with part of the stitch extending off the fabric.
- 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.
Ladder Stitch
To create a ladder stitch, sew with right sides of the fabric together. The needle thread will be the prominent thread that creates the ladder.
(Diagram description: Diagrams show examples of 2-thread and 3-thread flatlock stitches, standard and ornamental flatlock stitches, and 2-thread and 3-thread ladder stitches.)
Corded Overlock
Corded 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.
- Insert the cord through the hole in the front of the foot.
- Position the cord under the foot to the back of the machine and sew the garment seam.
- The cord is attached in the stitch as the seam is sewn.
(Diagram description: A diagram shows a cord being incorporated into an overlock stitch.)
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 the Thread Chain
- Thread the chain into a large eyed, hand sewing needle.
- Insert the needle into the end of the seam and pull the chain into the seam to secure the threads.
Machine Maintenance
An overlock requires more frequent maintenance than a conventional 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 the lint brush from the accessory case.
(Diagram description: A diagram shows a lint brush being used inside the sewing machine.)
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. 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.
(Diagram description: A diagram shows oil being applied to specific moving parts of the sewing machine.)
Replacing the Stationary Cutter
Turn off the main power switch and unplug the machine.
The stationary cutter should be changed when it becomes dull. The stationary cutter can be replaced according to the following directions. If you are having any difficulties, consult your dealer to make the necessary adjustments.
- Open the front cover and set the movable upper cutter (1) in nonworking position.
- Loosen the stationary cutter set screw (2) and remove the stationary cutter (3).
- Place a new stationary cutter in the groove of the stationary cutter holder.
- Tighten the stationary cutter set screw (2).
- Return the movable upper cutter (1) to its working position.
- Turn the handwheel so the needles are in their lowest position.
- Make sure the front edge of the movable upper cutter is 1-2 mm lower than the cutting edge of the stationary cutter.
(Diagram description: A diagram shows the stationary cutter (3) being removed and replaced, with screws (2) and the movable upper cutter (1) indicated.)
Storage
When the machine is not in use, be sure to keep it unplugged. Cover the machine with the vinyl cover to protect it from the dust. Store the machine so it is not exposed to direct sunlight or humidity.
Servicing
If you have any questions regarding service and/or operation, contact the store where the machine was purchased.
