99
Looper cover
Push the looper cover 7 fully to the right and
then swivel it down. Five types of stitches
and their threading paths are portrayed in
color on the inside of the looper cover.
Note: The electricity supply of the machine
is cut off as soon as the looper cover or
swivel plate 12 is opened, for safety reasons,
i.e. sewing with the machine is no longer
possible.
Waste container
Insert the upper latch of the waste container
45 into the upper slot of the looper cover 7.
Apply pressure to the lower part of the
container until the lower latches fl ick into
place in the lower slots of the looper cover.
1010
To remove the waste container, repeat this
procedure in the reverse order.
Spool holder
Before placing thread cones/spools on
machine you must pull the spool holder 34
fully away from the back of machine.
Telescopic thread guide
Pull the telescopic thread guide 32 upwards
to its highest position.
To ensure optimum thread feed, turn the
telescopic parts slowly until you hear the
locking balls fl ick into place.
Thread net
Synthetic threads generally unwind too
quickly from the thread spool. Thread nets
have been included to allow easy use of
these threads. Pull the thread net (located
in the accessory box) over the spool from
below. Place the spool on the spool holder
catching the bottom of the thread net with
the spool pin.
Thread unreeling disc
The thread unreeling disc (in the accessory
box) is used for small spools/spools with
notched or rough ends. Place the spool on
the spool pin 35. Place the thread unreeling
disc on top of the spool. Make sure the spool
dise 37 is used under the spool.
1111
Spool disc/cone thread adapter
It is advantageous to use the spool dise
37 when sewing with large spools (5,000
10,000 m). To do this, place the cone thread
adapter 36 onto the spool pin 35. With
synthetic threads, the spool discs help
eliminate vibration of the cones/spools
aiding in smoother feeding of the threads.
Clip on thread guide
Use the clip on thread guide accessory when
sewing with decorative thread. Clip this onto
the telescoping thread guide 32 and thread
the machine as shown in the illustration. Use
the thread net and/or the thread unreeling
disc if needed.
Presser foot lifter
The presser foot can be raised and lowered
using the presser foot lifter 43. The
maximum vertical lift of 6.5 mm for the
presser foot for particularly thick fabrics can
be achieved by pressing the presser foot
lifter towards the rear.
1212
Once an initial thread chain has been
created, the presser foot lifter no longer
needs to be raised if you continue working
with the same thread and presser foot. It is
suffi cient to gently lift the front part of the
presser foot using your thumb. Slide the
fabric under the raised part of the presser
foot. The fabric is automatically taken up and
fed into the machine when you activate the
foot control.
Presserfoot
With standard presser foot 10 use setting
”A” on the spring loaded presser foot latch
for the cover stitch (Prog. 02), the 2 thread
chainstitch (Prog. 01), the 5 thread safety
stitch seam (Prog. 09) and the 4 thread
safety stitch seam (Prog. 08).
Transparent presser foot F from the
accessories can also be used for the cover
stitch (Prog. 02).
For all other programs use standard presser
foot 10 and setting ”B” on the springloaded
presser foot latch.
Changing the presser foot
Switch off the electrical power
To remove: Raise the needle(s) to the
highest position by turning the hand wheel
towards you. Raise the presser foot and
press lever A at the rear of the presser foot
holder. The presser foot will be released
automatically from the holder. Pivot the
presser foot clockwise until the front half of
presser foot clears holder and remove by
sliding foot away from you towards back of
machine.
To attach: Place the presser foot behind and
perpendicular to the presser foot holder.
Pivot the presser foot counterclockwise
until the pin of the foot is directly under the
presser foot holder clamp. Lower the presser
foot lever and press lever A, if necessary,
until the foot then clicks into place.
Check: Please lift the presser foot lever to
ensure that the presser foot is properly
locked into place.
1313
Needle position
This machine has 4 needle positions and can
sew with a maximum of two needles at any
one time. The needle positions are 1 1, L2,
R11 and R2. The fastening screw is located
directly above the corresponding needle.
Note: If the needles 1 11 and L2 have been
inserted, the left needle will be somewhat
lower than the right needle.
The different needle positions are depicted

Important note on threading
The needle(s) must always be threaded last
so that the needle threads do not run under
the looper thread as seen in drawing 1, but
instead over the looper thread as depicted
in drawing 2. Should this sequence not be
followed, thread breakage or missed stitches
can occur.
If the looper threads break, you must
pull the needle threads out of the needle
eye, rethread the loopier thread and then
rethread the needle threads.
Changing a spool on a threaded machine
Cut the threads off close to the spool and
replace with new spools. Tie together the
threads which are still in the machine with
the new threads, and pull the threads out
of the needle eyes. Raise the presser foot.
Pull on the needle threads until the knots are
about 6 inches (15 cm) past the last thread
guide in front of the needles. Cut the knots off
and pull the threads through the respective

To return the machine to its previous
settings after sewing with the cover stitch or
two thread chainstitch:
Open the looper cover and remove the
power table.
Move the looper disengaging lever to the
right, thus re-engaging the upper overedge
looper.
Bring the swiveling stitch width latch into the
basic position (see page 31) and engage the
upper blade (see page 30).
Push the blade guard into the looper cover
and close the looper cover.

Differential feed
The differential feed consists of two feed
dogs (A + B), one behind the other, which
feed the fabric. The movement of the
front feed dog (A) and thus the amount of
material to be fed can be regulated using
the regulator wheel 41. The setting range is
between 0.5 and 2.0.
The standard setting is 1.0, where the
movement of the front feed dog (A) is
synchronized with the rear feed dog (B).
This means that the front feed dog feeds the
same amount of fabric as the rear feed dog.
Note:
The function of the differential feed also
depends on the set stitch length and the type
of fabric being used.
Set the regulator wheel for the differential
feed 41 to 0.5. At this setting the front feed
dog feeds half as fast as the rear feed dog.
This means that the front feed dog feeds
only half as much fabric as the rear feed dog,
causing the fabric to stretch.
3838
Here you will avoid gathering/puckering
of the seam when working with very light
fabrics, such as silk and taffeta. Instead, a
smooth seam (A) will be achieved.
You can also achieve decorative effekts with
the differential feed dog. For example the
wavelike effect when using a rib knit (B).
Set the regulator wheel for the differential
feed 41 to 2.0.
Here the front feed dog feeds twice as fast
as the rear feed dog. This means that the
front feed dog feeds twice as much fabric
as the rear feed dog, causing the material to
gather.
The following table contains information on the differential feed settings. However, you
should always test your setting fi rst on a piece of scrap fabric.
Type of fabric / effect
Very light fabrics: silk, satin, poplin, taffeta, linings.
Normal fabrics: light and medium-heavy cottons, fi ne cords,
thermal-wear.
Light knitwear: jerseys, polo fabrics, cut-pile pullovers, tricot,
fi ne knitwear and gathered fabrics.
Heavy knitwear: sweatshirt fl eece, heavy gathered fabrics,
heavy knitwear.
Stretch - wavelike effect: medium and light knitwear, jerseys,
knitwear, ruffl ed sleeve and collar edges, skirt hems, dense
stitch lengths.
Here you will avoid stretching in the seam
when working with knitwear, such as jerseys
or gathered fabrics. Instead, a smooth seam
(A) will be achieved.
You can also achieve decorative effects
with the differential feed dog. For example
the gathering effect when using very light
fabrics (B).
Differential feed setting
gather
<2.0>
normal
<1.0>
stretch
<0.5>
Gathering: ruffl ing light materials and lace, seam allowances
for curves, arches on blouses, shirts, skirts, round pockets,
fl aps, stretching or gentle ruffl ing of arched sleeves
(shoulders), sleeve widths for cuffs or gathered fabrics.
3939
Adjusting the stitch length
You can set the desired stitch length
between 0.5 mm to 4.0 mm by turning the
stitch length adjustment knob (42).
Note
For the two thread chainstitch, the setting
should be 3.0 or higher.
Removing the needle plate
Raise the presser foot and move the
needle(s) to the highest position. Remove
the presser foot and open the swivel plate.
Press down the needle plate disengaging
lever 26. The needle plate 11 is raised out of
its mount. The needle plate can be removed
to the left.
Note:
The machine should be unthreaded when
removing the needle plate.
4040
Inserting the needle plate
Place the needle plate to the rear on the
guide pin (A) and press down at the front
until you hear it click into place.
Securing the upper blade
Switch off the electrical power
It is recommended to secure the movable
upper blade 23 before sewing heavy fabrics.
Raise the needle(s) to its highest position and
open the swivel plate. Tighten the screw fully
using the Allen key. This screw should always
be slightly loosened again after sewing heavy
fabrics.
Note:
The seam width can no longer be adjusted
once the upper blade is secured.
Setting thread tension
The following pages contain directions for setting thread tensions for all programs. Adjust
the tension by turning the tensioning wheel until the dot marker is at the desired setting.
The settings for adjusting thread tension are recommendations. Fabric type, thread quality
and needle gauge will infl uence seam results. Always sew off a test seam onto a piece of
scrap fabric and check the thread loops. Adjust the thread tension if necessary.
Adjusting the tension settings is described on pages 46 to 56.

Important notes on sewing with the cover
stitch
The power table is marked with various units
of measurement. The upper fi gures are in cm.
The lower fi gures are in inches.
Note: The hemmer guide H2 is available as
an optional accessory. With this optional
accessory you can hem your fabric
effortlessly without having to press under the
hem edge prior to sewing the cover stitch.
Preparing the fabric:
When not using the H2 optional accessory
guide, it is useful to press under the fabric
edge before hemming it. The width of fabric
to be pressed under must be 0.5 cm wider
than the fi nished hem width. Example: Press
under a one inch (2.5 cm) fabric width to sew
a fi nished hem of 3/4 inch (2 cm).
Note: Set the seam width at 3.5 cm.
To start sewing:
Raise the presser foot and place the fabric
under the presser foot so the needles pierce
the fabric for the fi rst stitch. Position the
fabric at the desired width using the marked
guidelines on the power table. When starting
to sew, pull the fabric taut towards the rear
and sew slowly. The speed may be increased
as you sew further along the fabric.
4646
Finishing sewing:
1. When sewing to the end of the fabric:
Tightly hold the threads at the end of the
seam. Sew slowly off the fabric while lightly
pulling the threads toward the rear of the
machine.
Note: The differential feed may need to be
adjusted slightly to allow your fabric to lie
perfectly smooth. Test your settings fi rst on
a piece of scrap fabric.
2. If sewing on a tubular item, i.e. pant or
sleeve hem:
Sew around tubular item, oversewing 4-5
stitches at the beginning of your seam ’ After
the last stitch, turn the hand wheel towards
you until the needles pierce the fabric
and you have heard each needle ”click”
(just before the needles are in the lowest
position).
After the second ”click” tum the handwheel
away from you until the needles are in their
highest position. Raise the presser foot (this
will release the tension on the threads). Hold
the threads tightly at the end of the seam
and pull the fabric from the machine. Cut the
threads. Pull the threads through to the back
of the fabric and knot them.
Edge guide
Push the edge guide (included in your
accessory box) into the guide holder A
from the left. The edge guide can be set as
required by sliding it to the left or right.
The edge guide is useful for serging searm
at regular intervals with the cover stitch or
two thread chainstitch.
