1. Cut the thread in use 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 2-3 cm in length and Àrmly 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.
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.
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.
Thread chain
2. 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.
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 Ànger of the stitch plate. If the threads
do not wind around the Ànger, make sure each thread is
threaded correctly.
5. Continue holding the thread chain while pressing the foot
control. Sew until the chain is 5-8 cm 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 deÁect the
needle, causing it to break.
7. When you reach the end of the fabric, continue sewing while
drawing the Ànished fabric gently backwards and to the
left. This is called chaining off. It prevents the threads from
coming undone and prepares for next sewing.
Chaining off
Thread cutter
8. Cut off the thread chain 2-5 cm behind the presser foot
using the thread cutter on the back of the machine. Pull the
threads around the thread cutter from the right, then toward
you.

Thread tension settings
Right side
Upper looper thread
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
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.

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.

Presser foot pressure adjustment
The presser foot pressure is pre-set for sewing based on normal
conditions. Adjustment might in some conditions be necessary.
Increase or decrease the pressure until you are satisÀed 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
knob in counter-clockwise direction.
More pressure: Increase the pressure by turning the adjustment
knob in clockwise direction.
Back to standard setting: Turn the adjustment knob until the
mark on the knob is in line with the arrow.
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 Àne tuning the cutting width, using the width adjustment
knob further adjustment 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.
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 Ànger lever setting
The stitch Ànger lever should be set to “S” for all standard
overlock sewing. To sew rolled edge you need to retract the
stitch Ànger by setting the stitch Ànger lever to “R”. When
moving the stitch Ànger, be sure to push the lever as far as it
will go in each direction.
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 Ànger 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
1. Attach the 2-thread overlock converter (see page 8).
2. Use the right needle thread and lower looper thread.
3. Move the stitch Ànger lever to “R”.
4. Set the stitch length dial to “1-2” for a Àne seam.
5. Set the thread tension according to the stitch table on pages
23-26.
6. 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.

17
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 Áatten the seam. The tensions must be adjusted
correctly for the fabric to pull Áat.
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.
2-thread Áatlock stitch
Standard Flatlock Stitch
Standard Áatlock stitch
3-thread Áatlock stitch
Ornamental Áatlock stitch
1. Use the left needle.
2. For 2-thread Flatlock: Attach the two-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.
3. Set the thread tension according to the stitch table on pages
23-26.
4. Place the wrong sides of the two pieces of fabric together to
sew a decorative stitch on the right side of the garment.
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 Áat.
Ornamental Áatlock stitch
1. Place the movable upper cutter in the nonworking position.
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 garment.
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
Áatten.
Tip: The upper looper thread is the prominent thread in the
Áatlock 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.
2-thread ladder stitch
18
3-thread ladder stitch
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 stabilize 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.
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
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.

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 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.
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.
20
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 difÀculties, consult your dealer
to make the necessary adjustments.
1. Open the front cover and set the movable upper cutter (1) in
nonworking position.

2. Loosen the stationary cutter set screw (2) and remove the
stationary cutter (3).
3. Place a new stationary cutter in the groove of the stationary
cutter holder.
4. Tighten the stationary cutter set screw (2).
5. Return the movable upper cutter (1) to its working position.
6. Turn the handwheel so the needles are in their lowest
position.
7. Make sure the front edge of the movable upper cutter is 1-2
mm lower than the cutting edge of the stationary cutter.
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.

Please note:
The settings shown in this table are our recommendations
based on normal conditions. It may be necessary to adjust
the thread tension according to 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 garment.
