Introduction6
Optional accessories from INSPIRA™
Optional presser feet specially prepared for this machine are available at your PFAFF® dealer.
The snap-on type presser foot used on this machine allows easy removal and replacement.
Elastic Foot 620 08 65-96
The Elastic Foot guides and stretches narrow elastic
(¼-½”, 6-12mm) as you sew it to fabric. It is great for
sewing for active wear, lingerie and other elastic insertion
techniques.
Blindhem & Lace Foot 620 08 69-96
The Blindhem Foot is perfect for sewing invisible hems
and for applying lace. The hem is sewn, overcast and
trimmed in one step.
Beading Foot 620 08 66-96
The Beading Foot smoothly guides beads and pearls
through a channel on the foot for easy application on
garments or crafts.
Piping Foot 620 08 67-96
The Piping Foot is perfect for inserting packaged piping
into seams and on edges for a tailored À nish. The trim
is sewn between the two layers of fabric in one step. A
groove under the foot helps guide the piping. You can also
create your own piping for a custom À nish.
The Piping Foot makes it fast and easy to cover cording
with fabric and to insert piping into seams for a
professional look!
Taping Foot 620 08 68-96
The Taping Foot is used to apply seam tapes to seams
to prevent stretching. It is especially good for stabilizing
shoulder seams. With this foot you can reinforce and
construct seams in one step.
Some fabrics have a lot of excess dye which can cause
discoloration on other fabric but also on your overlock
machine. This discoloring may be very difÀ cult or
impossible to remove.
Fleece and denim fabric, especially red and blue, often
contain a lot of excess dye.
If you suspect that your fabric/ready-to-wear garment
contains a lot of excess dye, always pre-wash it before
sewing to avoid the discoloring.

Needle threader
To make threading the needles easier, use the needle
threader included with the accessories.
• Turn the handwheel so the needles are in their highest
position and lower the presser foot. Make sure one
of the rectangular markings of the needle threader is
pointing upwards. Place the thread from right to left in
the notch on the tip of the needle threader.
• Hold the needle threader against the needle. Move
the needle threader down to the needle eye and press
gently against the needle, causing a small metal pin
to push the thread through the needle eye and form a
thread loop.
• Use the needle threader to pull the thread loop out
behind the needle.
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
À rmly pull both threads to test knot security.
• Raise the presser foot to release the tension discs.
• 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.
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.

Stitch overview
The settings shown in this table are our recommendations based on normal conditions. The correct tension is set
automatically when selecting a stitch. 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 steps of no greater than half a
number at a time. Always test sew on a sample of your fabric before sewing on your garnment.
Different stitches are obtained by combining different needle positions, threading methods, and the use of the 2-thread
converter.

Stitches & sewing techniques 33
Start sewing
Pin Placement
When securing the fabric pieces using pins, insert straight
pins to the left of the presser foot. The pins will be easy to
remove and are away from the cutters.
Sewing over pins will damage and might destroy the
cutting edge of the cutters.
• 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 pull them slightly.
• Turn the handwheel toward you two to three complete
turns to start making a thread chain. Check if all
threads wind around the stitch À nger of the stitch plate.
If the threads do not wind around the À nger, 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 (2-3”) 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 deÁ ect the needle, causing it to break.
Chain off
• When you reach the end of the fabric, continue sewing
while drawing the À nished fabric gently backwards
and to the left. This is called chaining off. It prevents
the threads from coming undone and prepares for the
next sewing task.
• Cut off the thread chain 2-5 cm (1-2”) 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.
Tip: When you have re-threaded the machine, always chain off
and test sew a sample to test thread tension.
Tip: The presser foot on this machine has marks to indicate the
needle position. Use this as a guide when sewing.
Stitches & sewing techniques34
Rolled edge sewing
The rolled edge stitch is appropriate for lightweight fabrics such as lawn, voil, 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 a rolled edge you need to set the stitch À nger lever to R. (See
page 11)
Tip: For a beautiful rolled edge, thread the upper looper with a decorative thread and the needle and lower looper with lightweight
regular thread.
Note: Make a thread chain and test sew on a sample of your fabric before sewing on your garment. Hold the thread chain before
sewing to keep it from curling into the seam.
Note: The minimum overlock stitch width that can be obtained for rolled edging is approximately 1.5 mm.
Coverstitch sewing
The coverstitch can be used for covering, binding or top-stitching necklines and for hemming the bottom of T-shirts
and sweatsuits, etc. in addition to Á at joining seams (plain seaming).The coverstitch is most suitable for stretchy fabrics.
It can also be used for woven fabrics.
Machine set up
• Disengage the movable upper cutter. (See page 10)
• Set the stitch À nger lever to R. (See page 11)
• If inserted, remove needle B and needle A.
• Install needles C, D and/or E depending on desired coverstitch.
• Disengage the upper looper. (See page 11)
• Remove cutter cover A and install coverstitch table B (see page 11). The graduations on the coverstitch table indicate
the distance, in cm and inches, from coverstitch middle needle. Use it as a guide when positioning the fabric edge.
• Close front cover.
Start sewing
• Raise the presser foot by lowering presser foot lift.
• Place material under the presser foot behind the needle.
• Lower the presser foot by raising the presser foot lift.
Note: When you start to sew from the middle of the fabric, place the fabric at the desired starting point of sewing.
Securing the coverstitch seam end
Chaining off is not possible after sewing coverstitch because it causes the
seam to unravel when the looper thread is pulled out at the end of sewing.
Therefore, secure the seam end in the following manner.
When sewing through to the edge of fabric
• Knot the needle threads (2 or 3 threads) together À rst, as shown on the
illustration.
• Tie these threads with the looper threads.
• Cut extra threads.
When sewing is stopped halfway
• Pull out the needle threads (2 or 3 threads) on the underside of the fabric
and knot the threads in the same manner as described above.
• Cut extra threads.
Note: Normally, the seams at the start of sewing do not unravel, but it is wise to
secure the seam end following the same steps as described when sewing through to the
edge of the fabric.
Standard Á atlock stitch Ornamental Á atlock stitch
3-thread ladder stitch
Stitches & sewing techniques 35
Flatlock sewing
A Á atlock stitch is made by sewing the seam and pulling the fabric apart to Á atten the seam. The Á atlock stitch
can be used both as a decorative construction stitch, sewing two pieces together (Standard Á atlock stitch), or for
embellishment on only one piece of fabric (Ornamental Á atlock stitch).
There are two ways to sew a Á atlock 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 Á atlock stitch
• Use the left or the right needle.
• For 2-thread Á atlock: Engage the 2-thread converter
(see page 10). Thread the lower looper and the left (A)
or right (B) needle.
For 3-thread Á atlock: Thread the lower and upper
looper and the left (A) or right (B) needle.
• 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 Á at.
Ornamental Á atlock stitch
• Disengage the movable upper cutter (see page 10). 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 from the right side of the garment (at
the fold).
• 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 Á atten.
Tip: The upper looper thread is the prominent thread in the
Á atlock 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.
A
B
Stitches & sewing techniques36
Chainstitch sewing
The chainstitch is sewn with two threads, one needle and one looper. Normally, the machine trims the fabric edge
while the seam is being sewn. However, a chainstitch seam can be placed at a desired distance from edge of fabric by
putting the upper cutter in B position, disengaging the upper looper and installing coverstitch table B. (See page 10-11)
Turn off the main power switch and unplug the machine.
Machine set up
• Disengage the movable upper cutter. (See page 10)
• Disengage the upper looper. (See page 11)
• Remove cutter cover A and install coverstitch table B (see page 11). The graduations on the coverstitch table indicate
the distance, in cm and inches, from coverstitch middle needle. Use it as a guide when positioning the fabric edge.
Start and end of sewing
When starting to sew after threading the machine, sew 2-3 cm on a scrap fabric and chain off to make a chain. At end of
sewing, pull the fabric lightly to the rear of machine and chain off.
Sewing hints
Pintuck sewing
Sew decorative pintucks on the fabric before cutting
out the garment. Use overlock right needle and select
3-thread overlock, narrow.
Note: The rolled edge stitch can also be used for this technique.
• Disengage the movable upper cutter. (See page 10)
• Mark the fabric with the desired number of pintucks
using a water-soluble fabric marker.
• Fold the fabric with the wrong sides together and sew.
• Press the pintucks in the same direction.
Sew in Circles
(only suitable for heavy and medium weight fabrics)
The extension table has 13 holes in it, used to sew in
circles.
Sew circles with the movable upper cutter engaged (A
position, see page 10) to get a beautiful edge, or disengage
the movable upper cutter (B position, see page 10) and
sew circle embellishments.
• Mark a dot in the center of the area that will be the
circle and place stabilizer under the fabric.
• Pierce the fabric at the mark with the sharp
end of the push pin (A). Place the pin into
the selected hole on the extension table. Push
the pin and its bottom plate (B) together.
• Lower the presser foot and sew. The fabric
will feed in a circle around the push pin.
• When the circle is complete, overlap the seam for a few
centimetres (an inch). Thread the threads into a large
eyed, hand sewing needle and pull them to the wrong
side of the fabric and secure.
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.
Braiding by chaining off
1. Disengage the movable upper cutter. (See page 10)
2. Insert À ller cord such as yarn or twill tape through the
hole in the front of the foot.
3. Position the À ller cord under the foot and chain off the
desired length.
4. Chained off braids can be used individually or woven
into 3 or 4 ply braids.
Lowering the needle(s)
When you stop sewing, the machine always stops with
the needle(s) in the up position. Tap the foot control one
time to lower the needle(s) into the fabric. The needle
down position is useful to hold your fabric in place when
making adjustments or when turning the fabric to change
direction when chainstitch sewing.

Stitch adjustments 37
Stitch width adjustment
The stitch width can be increased or decreased by
changing the needle position or with the cutting width
dial.
Width adjustment by changing needle position
A) When only the left needle, or when both needles are
used the stitch width is 6 mm.
B) When only the right needle is used the stitch width is 4
mm.
C) When using the chainstitch needle the stitch width is 9
mm.
Width adjustment with the cutting width dial
By À ne tuning the cutting width using the cutting width
dial further adjustments are possible within the range
shown below.
• When only the left needle is used: 5 - 7 mm
• When only the right needle is used: 3 - 5 mm
• When using the chainstitch needle: 8 - 10 mm
Turn the dial to adjust the desired seam width. For
standard setting the dial should be set to 6.0.
Presser foot pressure adjustment
The presser foot pressure for sewing based on normal
conditions should be set to 2.5. Adjustments in some
instances may be necessary. Increase or decrease the
pressure until you are satisÀ ed 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 dial in counter-clockwise direction to a value
between 2.5 and 1.
More pressure: Increase the pressure by turning the
adjustment dial in clockwise direction to a value between
2.5 and 5.
Back to standard setting: Turn the adjustment dial until
the mark on the knob is set to 2.5.
Stitch length adjustment
Stitch length is automatically set when selecting a stitch
but it may have to be adjusted depending on fabric
type. Adjust the stitch length to 4 mm when sewing on
heavyweight fabrics. Adjust the stitch length to 2 mm
when sewing on lightweight fabrics.
To adjust the stitch length, touch the stitch length icon. It
becomes surrounded by a black frame, showing that it is
selected. Touch - or + to adjust the stitch length.

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.
The differential feed is automatically set to 1.0 when
any of the coverlock™ 4.0 stitches is selected. This is the
setting for overlock stitching on normal fabric. To adjust
the differential feed, touch the differential feed icon. It
becomes surrounded by a black frame, showing that it is
selected. Touch - or + to adjust the differential feed.
Gathered overlock (stretch, knit fabrics)
When overedging stretch fabric, such as knits and jersey, adjust the differential feed to a value between 1.0 and 2.0. The
setting depends on the material being sewn as well as the desired amount of gathering. Test sew with different settings
before sewing on your garment.
Stretch overlock (lightweight fabrics)
When overedging light woven or loosely knit fabrics, such as silk and silky knitwear, adjust the differential feed to a
value between 0.6 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 desired amount of stretching.
Test sew with different settings before sewing on your garment.
Stitch adjustments 39
Thread tension À ne tuning
Thread tension is automatically set when selecting a stitch but it may have to be À ne tuned depending on:

Maintenance 41
Machine maintenance
An overlock machine requires more frequent maintenance
than a conventional machine mainly 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.
• Close the front cover and wipe the exterior surface of
your machine with a soft cloth to remove any dust or
lint built up.
Cleaning the touch screen
Wipe the touch screen with a clean, soft and damp cloth.
Oiling
Turn off the main power switch and unplug the machine.
To keep the machine running smoothly and quietly
the moving parts, pointed out on the picture, must be
lubricated often.
Use supplied 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 movable upper cutter
Turn off the main power switch and unplug the machine.
The movable upper cutter should be changed when it
becomes dull. The upper cutter can be replaced according
to the following directions. If you are having any
difÀ culties, consult your authorized PFAFF® dealer.
• Open the front cover and set the movable upper cutter
(1) in A position (See page 10).
• Loosen the set screw (2) and remove the upper cutter
(1).
• Turn the handwheel until the upper cutter holder is in
its lowest position.
• Place a new upper cutter in the groove of the upper
cutter holder and tighten the set screw (2).
• Make sure the front edge of the movable upper cutter
is 0.5-1.0 mm lower than the cutting edge of the
stationary cutter (3).
Maintenance42
Storage
When the machine is not in use, be sure to keep it unplugged. Cover the machine with the dust 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 your local PFAFF® dealer.
