Foot pedal
l
The machine will begin to sew at a slow speed as soon as the foot pedal
l
is gently activated. The sewing speed of the machine will increase when more pressure is applied to the foot pedal
l
. The machine will stop running when you take your foot from the pedal, as pressure is no longer being applied to the pedal
l
.
Attention!
Ensure that you do not place any objects on the foot pedal l, as this could lead to unintentional running of the machine.
Changing the sewing needles
Important
Remove the power plug kfrom the wall socket! Otherwise the appliance could run unintentionally.
1. By turning the handwheel 0bring the needle shank into the highest
possible position.
2. Apply pressure to the sewing foot lifting lever
g
so that the sewing
foot
s
is lowered onto the stitching plate a.
3. Remove the needle by loosening the retaining screw
f
.
4. Turn the new needle into a position whereby the flattened side of
the needle is pointing to the rear and insert the needle as far as it will go into the needle clamp from below.
5. Tighten the retaining screw.
Checking the needle
1. Sewing needles must always be straight and, so that the sewing
procedure is smooth, must possess a faultless point.
2. Lay the flat side of the needle onto a smooth, even surface to check
if the needle is bent. This permits the easiest ascertainment of whether the needle is bent or not.
3. Replace the needle whenever it is broken or blunt.
Changing the sewing foot
Dependant on the type of sewing you wish to carry out, it may be necessary to exchange the sewing foot
s
.
Important
Remove the power plug kfrom the wall socket! If you do not, the appliance could start to run unintentionally.
1. By turning the handwheel 0(towards you, in an anti-clockwise direction)
bring the needle into the highest possible position and raise the sewing foot lifting lever
g
and hence the foot bar.
2. Loosen the foot by carefully pressing the unlocking lever at the rear of
the spindle of the sewing foot upwards.

Setting the stitch length
Depending on the type of stitch you have set, it may be necessary to adjust the stitch length appropriately to achieve the best possible sewing results.
The numbers on the thumb wheel of the stitch length selector
6
correspond to the respective stitch length in millimeters (mm), hence, A HIGHER NUMBER MEANS THAT THE STITCH WILL BE LONGER.
When the stitch length selector is set at „0“
6
there will be no feeding
of the product to be sewn. This setting is used for sewing buttons on.
The range designated with „F“ is used for the creation of so-called satin stitches (zigzag stitches sewn very closely together). Satin stitches can be used to sew button holes or as embroidery stitches. The appro­priate setting within the „F“ range required for special cases is depen­dant on the fabric and the sewing silk used. To find the respective re­quired setting, you should first try out the stitch and stitch-length settings on remants and, at the same time, observe the feeding characteristics, varying the settings until the desired results have been obtained.

Sewing backwards
To sew backwards, press the sewing direction reverse switch tas far as it will go, keeping it pressed while simultaneously activating the foot pedal
l
.
To resume sewing forwards stop applying pressure to the sewing direction reverse switch
t
, whereupon the machine will immediately change over to sewing in a forward direction. The stitching backward function is employed to finish off and reinforce seams.
Threading the needle and preparation
Engaging the spool
1. Tip the thread spool carrier 5upwards and fix a spool of thread on the carrier. Secure the spool with a thread spool holder
x/c
of the
appropriate size.
2. Lay the felt pad
n
on the winder spindle 8and then place an empty
bobbin on the spindle.
3. Draw the thread through the upper thread guide
1
.
4. Wind the loose end of the thread a few times around the empty bobbin in a clockwise direction.
5. When the first loose end windings of the thread are tautly wound around the spool, press the spool with the winder spindle
8
against
the spool stop
9
.
6. Pull the handwheel 0on the right side of the machine out a little to disconnect the sewing mechanism from the motor.
7. Now switch the sewing machine on and step on the foot switch l. When the bobbin is full, cut the thread.
8. Press the winder spindle
8
back to the left and remove the full spool.
9. Press the handwheel
0
back in – otherwise the sewing mechanism
of the machine will remain disconnected from the motor.
Inserting the spool
Important
Remove the power plug kfrom the wall socket! Otherwise, the appliance could run unintentionally.
1. By turning the handwheel 0(towards you in an anti-clockwise direction) bring the needle into the highest possible position and release and raise the foot with the lifting lever
g
.
2. Access the bobbin case carrier by removing the sewing table extension
p
in the manner described above. Open the flap of the sewing table. Remove the bobbin case by drawing its clip towards you (flap), then remove the entire case by pulling it out from the retaining pin towards you.
3. Unwind approximately 10 cm (4”) of the thread from the bobbin and insert the bobbin into the bobbin case. Hold the bobbin case during the process. Draw the thread you have unwound downwards and then leftwards into the slit in the bobbin case, until the thread runs into the outlet slit under the spring tab.
Page 9
- 7 -
4. Insert the bobbin case in the carrier, holding the case by the catch and then releasing the catch. The driver
o
on the outside of the
bobbin case must catch in the notch
z
on the top of the case carrier.
Notice
If the bobbin case has not been correctly inserted in the carrier, it will fall out as soon as you commence sewing.
Threading the upper thread
1. Raise the sewing foot sby activating the lifter lever gas illustrated.
2. By turning the handwheel
0
(in an anti-clockwise direction) bring the
needle into the highest possible position.
3. Slide a spool with thread onto the horizontally located thread spool carrier
5
, then press one of the two supplied thread spool carriers
x/c
onto the pin so that the thread spool is held in place.
Notice
Select spools of thread complying with the thread spool carrier x/
c
in shape and size. The external diameter of the selected thread spool carrier
x/c
should be slightly greater than the external diameter of
the winding on the spool of thread.
4. Feed the thread you have unwound from the spool through the thread guide, as is illustrated in the diagram and on the machine.
Notice
Ensure that the thread is threaded from right to left through the eye of the feeding lever
j
. When you thread the needle with the upper thread make sure that the needle is threaded from the front to the back and that the loose end of the thread has a length of at least 15 cm (6“) from the needle eye. Use the threading aid
G
to thread the needle.
Insert the loop of the threading aid
G
through the needle eye from the rear. Pass the tread through the loop then carefully pull the threa­ding aid
G
back. The thread will be automatically drawn through
the eye of the needle.
Retrieving the lower thread
1. Bring both the sewing foot sand the needle into the higest possible position.
2. Grasp the end of the upper thread with your left hand and then turn the handwheel
0
(in an anti-clockwise direction), until the needle
has moved down and then up into the highest position.
3. Normally the upper thread will then „catch“ the lower thread in a loop and bring it to the top. Pull the end of the upper thread towards you and the spool will be released in a large loop of the lower thread.
4. Draw approximately 15 cm (6“) of both threads from the spool respectively from the bobbin. Lay the upper thread upside down between the toes of the sewing foot
s
, then draw it in the direction of the appliance rear. Lay the lower thread, just like the upper thread, but slanting rear right in the direction of the appliance rear.
Sewing with the twin needle
Your machine is also designed for sewing with twin needles C, meaning, you can sew with two upper threads simultaneously. These two upper thre­ads can be the same colour or – for decorative purposes – different colours.
Adjust the setting wheel single needle – twin needle
4
to the symbol
„twin needle”.
Inserting the twin needles
C
The twin needles Care inserted principally in the same manner as single needles. Also in this case the flattened side of the needle shaft must be pointing to the rear and the rounded side of the shaft cross section must be pointing to the front.
Positioning the additional thread spool carrier
Insert the vertical thread spool carrier into the opening 7on the machine upper side close to the horizontal thread spool carrier
5
. Place the second
spool of thread onto the vertical thread spool carrier.
Threading the twin needles
C
Each of the two needles must be threaded separately.
1. Threading the needle on the right
Proceed in the same manner as threading single needles using the thread from the spool on the additional thread spool carrier
b
.
Draw the thread through the thread guide on the right.
2. Threading the needle on the left
Thread the needle on the left in the same way as the needle on the right, however, draw the thread through the guide on the left before you draw it through the eye of the left-hand needle.
Inserting the lower thread
The spool of the lower thread is inserted in the same way as with a single needle (see Chapter „Threading the sewing silk and preparation”).
Tensioning the thread
The tension of the thread has a fundamental influence on the quality of the stitches. It may be necessary to adjust the thread tension if you change the thread or sew a different kind of fabric.
Notice
Before you actually commence sewing the fabric you should carry out a sewing test using a remnant of the same fabric, adjusting the thread tension if necessary until a satisfactory test result is achieved.
Possible fine adjustments of the thread tension and their consequences:
Upper thread tension is too high:
Small loops are visible on the top surface of the fabric.
³ Reduce the tension of the upper thread by turning the upper
thread tension selector
2
to a lower value.
Page 10
- 8 -
Upper thread tension is too low:
Loops are visible on the bottom of the fabric.
³ Increase the tension of the upper thread by turning the upper
thread tension selector
2
to a higher value.
Notice
The lower thread tension has been preset in the factory, ensuring that it is appropriate for general use. Hence, no changes in the setting are required for the majority of sewing tasks.
However, if you are sewing fine fabrics with thin thread, it could happen that the correct adjustment of the thread tension will not adjust automatically by means of the setting of the upper thread tension. Hence the user can readjust the lower thread tension in accordance with the procedure described below.
Lower thread tension is too low
Small loops are visible on the surface of the fabric.
³ First reduce the (upper-) thread tension, setting a lower value by
turning the upper thread tension selector
2
. If this does not lead to satisfac-tory sewing results, even when the upper thread tension is set at the lowest possible value, change the upper thread tension on the spool as described below.
Spool
³ Increase the tension of the lower thread at the bobbin, using a small
screwdriver
Y
to turn the screw on the pressure tab of the bobbin case in a clockwise direction. The screw should not be turned by more than one complete rotation.
³ Do not forget to turn the screw back into its original position before
you recommence sewing!
Correct thread tension
The correct thread tension is important, as a tension that is too high or too low will lead to a weakening in the strength of the seam and often also results in a rippling of the fabric surface in the vicinity of the seam.
Notice
1. Select the right needle size and thread strength according to the table above!
2. As a rule use the same thread strength for the upper thread (spool of thread) and the lower thread (bobbin)!

Straight stitch
The following types of stitches are defined as straight stitches:
Commencing sewing
1. Position the adjustment wheel of the stitch type selector wsuch that the desired number appears in the stitch-type window
q
. According to the
desired type of straight stitch you must turn the wheel to 2, 3 or 21.
2. Bring the needle into the highest possible position and raise the sewing foot
s
.
3. If nothing has happened: retrieve the lower thread by turning the handwheel
0
in an anticlockwise direction and drawing the upper
and lower thread together behind the foot.
4. Lay the fabric, respectively layers of fabrics, to be sewn on the sewing table under the raised sewing foot
s
, in such a manner that the need­le is located approximately 1 cm (3/8“) from the fabric edge and above the start of the seam.
5. Lower the sewing foot
s
.
6. In order to finish off the end of the seam, by sewing backwards, press the sewing direction reverse switch
t
as far as it will go and activate
the foot pedal
l
slightly. Backward sewing is used to combine two
seams as well as to reinforce seams.
7. After finishing sewing backwards change over to sewing in a forward direction, releasing the direction changeover switch
t
and briefly
taking your foot from the foot pedal
l
, then pressing the foot pedal
down once again
l
.
Changing the sewing direction
1. Stop the machine at the point where you wish to change the sewing direction, ensuring that the needle is piercing the fabric.
2. Raise the sewing foot
s
and align the fabric to the new sewing direc-
tion, whereby you can use the inserted needle as a turning point.
3. Lower the sewing foot
s
back down and then start sewing in the
new direction.
Finishing the seam
The backwards sewing function is also employed at the ends of the seam to secure and to reinforce the seam.
1. First sew in the forward mode until you reach the end of the seam, then stop the machine in this positon using the foot pedal
l
.
2. Press the sewing direction reverse switch
t
, then activate the foot
pedal
l
in order to sew backwards ca. 1 cm (3/8”) from the edge
or the end of the seam.
Type of stitch No. Stitch length
2 (with needle positioned
on the left)
1–4
3 (with central needle position)
21 (triple stretch stitch) firmly fixed at 2.5
Removing the fabric from the machine
1. Stop the machine.
2. Bring the needle into the highest possible position.
3. Raise the sewing foot
s
and carefully pull the sewn product out
towards the left.
4. Cut the two threads (Upper and lower threads) with the thread cutter on the rear of the foot bar.
Take note
The thread cutter is the indentation at the rear of the foot bar. Lay the thread that is to be cut into the indentation, hold the thread firmly to left and right of the foot bar and then draw it downwards.
5. To prepare the machine for sewing the next seam, pull approximately 10 cm (4”) from the upper and lower threads through the toes of the sewing foot
s
in the direction of the rear of the machine.
Edging seams and stretch materials
Stitch type No. 2 (simple straight stitch with needle position on the left) is used to sew hems and light-weight materials.
Stitch type No. 21 (straight triple stretch stitch) is used to sew stretch materials.
Sewing in zigzag stitches
Zigzag stitch
Set the stitch type number on the selector wheel waccording to the fixed stitch width of the zigzag stitch. Set the stitch length on the stitch length selector
6
. It is advisable to sew a few stitches in straight stitch at the beginning and end of a zigzag seam.
Satin stitch
The satin stitch (a close zigzag stitch, hence with very short stitch lengths) is achieved when the stitch length selector
6
is set in the „F“ range. The satin stitch can be used to sew buttonholes or for decorative purposes. The stitch width is also here determined from the selected type of stitch or stitch type number of the respective underlying zigzag stitch. Therefore, first select the type of stitch you require in accordance with the fixed width and then set the stitch length on the stitch length selector
6
within the „F“ range.
Type of stitch No. Stitch length
4 (stitch width 1.5 mm (1/16”))
F-45 (stitch width 3.5 mm (9/64”))
6 (stitch width 5 mm (13/64”))

Sewing blind hems
The blind hem stitch is used to finish off edges of sewn products, for exam­ple, the lower edges of trouser legs ensuring that the seam is not visible form the outside of the garment. Employ the blind hem stitch (stitch type No. 7) for non-elastic materials and the stretch blind stitch (No. 10) for elastic materials. Use the blind hem foot
F
.
1. Both threads should be the same colour as the fabric to be sewn.
2. Fold the material according to the desired seam as illustrated. Fold the material back from the edge, whereby an overlap of ca. 6mm (1/4”) should remain between the folded fabric edge and the required actual border.
3. Set the stitch type selector
w
at No. 7 or No.10.
4. Now sew accurately over the fold.
5. After you have folded the border once again the seam will be barely visible – typical for a blind hem.
Notice
The stretch blind stitch is especially suitable for elastic materials.
Sewing with the shell stitch
The shell stitch can be used to create a lacy wavy edge on relatively fine materials or to decorate exisiting borders.
1. Set the stitch type selector wat position 8.
2. Sew the fabric in a diagonal direction, arranging it under the sewing foot
s
in such a way that the straight sections of the stitch formation on the edge of the hem and the zigzag stitches are sewn a little over the fold.

Sewing with elastic stitches
The elastic stitch can be used in three areas of application: repair work („darning“), sewing on elastic bands (elastic braids) as well as for the edge to edge joining of pieces of fabric. All three areas of application will be described in greater detail below. In all cases set the stitch type selector
w
at number 9.
Darning
1. Set the stitch length selector 6at a value between „F“ and 2.5.
2. Reinforce the tear/„rent“ to be mended with a suitable piece of material at the back.
3. Oversew the damaged point in elastic stitch, following the run of the tear.
Sewing on elastic bands (rubber bands)
1. Position the elastic band on the material.
2. While sewing on elastic band and braid stretch the material forwards and backwards under the sewing foot with both your hands
s
.
Face to face sewing of pieces of fabric
The elastic stitch can be used to sew two pieces of fabric face to face and is especially suitable for the sewing of weaves and knits. The seam is barely visible when you use colourless nylon thread. Subject to the characteristics of the material edges you can either sew the open cut edges together or fold the edges prior to sewing.
1. Allow the material edges to be sewn together to touch each other and position the joint edge below the centre of the sewing foot
s
.
2. Sew the two pieces together using the elastic stitch, making sure that the two fabric edges or folded borders remain closely together without overlapping.

Two-fold rampart stitch
This type of stitch is used to sew two pieces of material together if there are no special requirements in relation to the elasticity of the seams, e.g. for patchwork. Set the stitch type selector
w
at number 11.
Scallop stitch
The machine can create a scallop stitch automatically, which may be used to decorate the edges of the items you have sewn.
1. Set the stitch type selector wat number 12.
2. Sew the scallop stich closely along the edge of the material.
3. If you wish, you can trim the outer curve of the pattern you have sewn after you have finished the edge. Make sure you do not cut through the stitches.
Additional decorative stitches
Both types of stitch may be used for the creation of (edge) decorative seams as well as smocking. Set the stitch type selector
w
at number 13 or 14.
Fishbone stitch
This stitch is used to join two pieces of fabric when a certain space between the edges or borders is required.
Notice
Use thicker upper and lower threads than is customary.

1. Fold together the edges of the two pieces of fabric to form a narrow hem, then tack the pieces onto a thin piece of paper, leaving a space of a few millmeters between the two borders.
2. Set the stitch type selector
w
at number 15.
3. Sew along the gap, at the same time pulling the upper and lower threads slightly in order to enable a correct formation of the initial stitches.
4. Remove the attached paper after finishing the sewing and close the seam by knotting the two threads at the beginning and the end of the seam on the underside of the material.
Finishing edges
These stitches are used to finish off pieces of fabric to prevent them from fraying and to hem them in one process. The arrow point stitch is ideal for finishing off a bed cover or table cloth, for example, whereas the elastic overlock stitch and the slanted overedge stitch is especially suitable for the finishing off of stretchable materials.
1. Set the stitch type selector
w
at 16, 18 or 19.
2. Position the fabric under the sewing foot
s
so that the line of the seam (the arrow points of the seam pattern formation) are positioned ca. 3mm (1/8”) left of the centre of the sewing foot
s
. This type of stitch is most effective when the seam line is approximately 6 mm (1/4”) from the edge of the material, because the stitching movement extending to the right (right zigzag points) grasps the fabric edge accurately and thus protects it from fraying.
3. If the distance between the sewing line (arrow points) and edge should become larger, you can trim the border to the right side of the seam.

Sewing material edges with feather stitch
Use the feather stitch as a decorative border stitch or to hem bed covers, table cloths and curtains or even for embroidery work.
1. Set the stitch type selector wat 17.
2. Position the fabric with the good side up on the sewing table of the machine and sew the seam ca. 1 cm (3/8”) from and parallel to the edge.
3. Trim the fabric close to the seam along the edge.
Besides this, the decorative effect of the feather stitch also prevents the fabric edge from fraying.
Sewing with three-fold zigzag stretch stitches
This type of stitch can be used to sew heavy stretch materials whenever a stitch with zigzag pattern is practical. It may also be used as a decorative edge stitch.
Set the stitch type selector
w
at 20.
Sewing buttonholes
Notice
1. It is advisable to practice the sewing of buttonholes on a remnant
of material before you actually attempt this on a garment.
2. If you want to sew buttonholes in soft and yielding materials,
it is adviseable to line the fabric with a stabilising material.
With appropriate practice and suitable settings of the machine, the automa­tic production of buttonholes in one working process is a simple method that delivers reliable results.
1. Mark the position of the buttonhole on the material with tailors chalk.
2. Attach the buttonhole sewing foot
N
(see Chapter „Changing the
sewing foot”) and set the stitch type selector
w
at 1.
3. Retrieve the lower thread.
4. Lower the sewing foot, so that the markings on the buttonhole foot
N
align with the chalk markings on the material as shown in the follo­wing diagram. The front closure of the buttonhole is sewn first.

8. Automatic production of the buttonhole takes place in the sequence of the steps 1 to 4 displayed in the diagram below.
9. Stop the machine when the two side buttonhole seams and the two finishings of the buttonhole have been completed.
Securing the edges and cutting the buttonhole
1. To secure the edging of the buttonhole, raise the sewing foot sand turn the material through 90° in an anti-clockwise direction on the sewing table and then lower the buttonhole foot
N
once again. Now sew in straight stitch (Stitch type No. 3) until you have completed the front fastening of the buttonhole.
2. Remove the material you have sewn from the machine. It is advisable to insert pins diagonally at both ends of a buttonhole to hinder a sepa­ration of the stitches.
3. With the thread cutter
J
cut out the buttonhole, slicing through the material in the centre between the two buttonhole seams. Proceed carefully in order to avoid cutting the stitches themselves.

Fine adjustment during sewing buttonholes
Should the buttonhole seams sewn on both sides of the buttonhole not be uniform in appearance, a fine adjustment can be undertaken as per the following method:
1. Set the stitch type selector
w
at „F“ and, as a test, sew the left-hand buttonhole seam on a remant of the same material. Observe the material feed during the process.
2. Should the sewn left-hand buttonhole seam be too coarse or too fine, appropriately adjust the material feed using the stitch length selector
6
.

3. When the sewing test has produced satisfactory results for the left­hand buttonhole seam with regard to the feed, sew a right-hand buttonhole seam and continue to observe the feed.
4. If the buttonhole seam on the right is too fine or too coarse in compari­son with the left, adjust the button hole fine adjustment screw at the rear of the machine housing as described below:
When the buttonhole seam on the right appears to be too coarse, adjust the screw using the supplied large screwdriver
X
in the direction marked „–“; When the right buttonhole seam is too fine, adjust the screw using the screwdriver
X
in the direction marked „ +“.
By means of the described method of adjustment it is possible to obtain a uniform appearance of the two buttonhole seams.
