IMPORTANT SAFETY INSTRUCTIONS
When using an electrical appliance, basic precautions including the following should always be
followed:
Read the complete instructions before operating this sewing machine.
DANGER - To reduce the risk of electric shock:
Unplug the power cord immediately after use and before cleaning.
WARNING - To reduce the risk of burns, re, electric shock or personal injury:
1. The sewing machine is not a toy. Increased caution is advised when the sewing machine is used
by or near children.
2. This appliance can be used by children aged from 8 years and above and persons with reduced
physical, sensory or mental capabilities or lack of experience and knowledge if they have been
given supervision or instruction concerning use of the appliance in a safe way and understand
the hazards involved. Children must not play with the appliance. Cleaning and maintenance
must not be carried out by children without supervision.
3. This sewing machine may only be used for the intended purpose described in this operating
manual. Use only accessories recommended by the manufacturer and covered in these instruc-
tions.
4. Never use the sewing machine if the cables or plugs are damaged, the machine does not func-
tion properly, has fallen to the ground or been damaged, or has even fallen into water. In such
cases, take the sewing machine to the nearest dealer or service center for inspection, repair or
electronic or mechanical readjustment.
5. Use the sewing machine only when no ventilation openings of the machine and the foot control
are blocked and keep them free of lint, dust and fabric residues.
6. Never insert objects into openings in the sewing machine or allow them to fall inside the
machine.
7. Do not use the sewing machine outdoors.
8. In addition, do not use the sewing machine in places where propellant gas products (sprays) or
pure oxygen are used.
9. To turn o the machine, set the power switch to the "0" position and then disconnect the power
plug from the power outlet.
10. Always pull the plug and never the cord when disconnecting the machine from the power
supply.
11. Keep your ngers away from all moving parts. Particular care must be taken in the area of the
sewing needle.
12. Always use the original needle plate. The use of an incorrect needle plate can cause the needle
to break.
13. Do not use bent needles.
14. Do not actively pull or push the fabric during sewing. This can lead to deection of the needle
and thus to needle breakage.
15. Switch o the machine (switch position "0") before you perform any activities in the needle
area, such as threading, changing the needle, changing the presser foot, and the like.
16. Always disconnect the sewing machine from the power supply before removing covers, oiling
the machine or any other oil the machine or carry out any other work intended to be performed
by the user and specied in this operating manual.
17. Observe the following to avoid injuries:
· Turn o the machine or unplug the power cord when leaving the machine unattended.
· Unplug the power cord before performing maintenance or replacing lamps.
CAUTION: Moving parts! To reduce the risk of injury, turn o the sewing machine before servicing.
Close the cover before operating the machine.

the needle to its highest position. Raise the
presser foot. Press the lever on the back of the
foot holder. The presser foot comes o.
Insert a presser foot:
Place the presser foot so that the pin on the
foot is aligned directly under the groove of the
foot holder. Lower the foot holder to secure
the foot.
EXTENSION TABLE / CONVERSION TO
Removing the table
Pull the table (1) away from the machine to the
left as shown, e.g. to sew cus and sleeves "free
arm" (2). The slide-on table can be used as an
accessory box.
Attaching the table
Carefully slide the extension table into the ma-
chine from left to right until it locks into place.
STITCH SELECTOR
Raise the needle above the fabric. Turn the dial
to select the desired pattern.
CAUTION: To avoid needle or fabric dama-
ge, make sure the needle is up or out of the
fabric while selecting a stitch.
REPLACING THE NEEDLE
1. Needle clamp screw
2. Needle clamp
3. Needle side
1. Turn o the power switch
2. Raise the needle to its highest position
by turning the handwheel counterclock-
wise towards you and lower the presser
foot.
3. Unscrew the needle clamping screw (1) by
turning it counterclockwise.
4. Remove the needle from the needle clamp.
Now insert a new needle into the needle clamp
with the at side (3) facing backwards. Push the
needle up as far as possible when inserting it
into the needle clamp (2).
Tighten the needle clamp screw (1) by turning
it clockwise.
CAUTION:
Never use a bent or dull needle!
A damaged needle can cause permanent hang-ups or running
stitches in knitwear, ne silk and silk-like fabrics.
To check whether a needle is bent, place the at
side of the needle on a at surface (e.g. stitch
plate or glass plate): The distance between the
needle and the at surface should be even.

again.
When the bobbin is
fully wound, it will
stop automatically.
Return the bobbin
winder to its original
position by moving
the spindle to the left.
Then cut the thread.
Press the handwheel
to the left to engage
the clutch.
The machine does
not function until the
clutch is engaged.
1. Place a bobbin in the bobbin case and make
sure that the thread is guided clockwise by
the bobbin.
2. Pull the thread through the slot in the
bobbin case.
3. Then pull the thread 10 cm through the
opening under the thread tensioner.
4. Hold the bobbin case by the ap latch and

SEWING BUTTON HOLES
To sew buttonhole you will need:
1. stitch selector
2. upper thread tension
3. buttonhole sewing foot
THIS IS HOW IT`S DONE
1.
Attach the buttonhole sewing foot as described
on page 8.
Carefully mark the buttonhole length on the
fabric. Place the fabric under the foot so that
the buttonhole mark is facing you.
Move the slider (A) towards you so that the top
mark (C) on the slider aligns with the start mark
(B). Lower the presser foot.

end just before the bartack to prevent the barta-
cks from cutting through. Cut the opening with
the buttonhole opener.
NOTE:
When sewing a
button hole on one
edge of the fabric, set
the end seam to slide
backwards as shown.
Turn the dial to adjust the

MAINTENANCE OF YOUR MACHINE
NOTE:
Turn o the power switch and/or disconnect the power plug before cleaning the machine. Do
not disassemble the machine other than as described in this section.
Cleaning the feed dog
1. Remove the needle and sewing foot. Remove
the throat plate screw (1) and the throat plate.
2. Clean with a brush and remove dust and lint.
They could clog the feed-dog line.
3. Reset the throat plate.
1. Move the needle to the highest position and open the hook cover.
2. Open the bobbin case ap and remove it from the machine.
Open the bobbin case ap and remove the bobbin case (1). Turn the handwheel until the hook path
is on the left (2). Turn the two hook holders (3a) outward and remove the hook track with hook.
Clean with a soft cloth and lubricate with sewing machine oil (1-2 drops).
Installing the feed-dog unit
Pay attention to the alignment of the gripper
unit (pos. 6 below). Insert the hook (4) so that it is
on the left. Then fasten the hook track (3b) with
the two hook holders (3a), making sure that the
