Upper thread breaks

Rethread the machine.

Threading the upper thread

Important: Set the main switch to ("O"). Raise the presser foot bar by lifting the two-step presser foot lifter and lift the thread lever by turning the hand wheel anti-clockwise. Follow the arrows and numbers on the sewing machine when threading.

1. Place the spool (n) on the spool pin and hold it in place with a spool pin cap (s).
- Small spool pin cap for thin threads
- Large spool pin cap for thick threads

2. Guide the upper thread through the upper thread guide and bobbin thread guide from right to left, then move it forward into the right slot and guide it downwards.

3. Guide it to the left under the guide lug (A) and then upwards again.

4. Guide the thread from right to left through the thread lever and then downwards.

5. Guide the thread first behind the large, metal thread guide (B) and then through the eye of the needle. Always thread the needle from the front.

Needle threader

You can use the needle threader as a threading aid.
1. Insert the needle threader through the eye of the needle from back to front.
2. Guide the upper thread through the wire loop of the needle threader.
3. Pull the needle threader together with the thread back through the eye of the needle.

Inserting the bobbin

Important: Turn power switch to off ("O").

When inserting or removing the bobbin, the needle must be fully raised.

1. Open the hinged cover.

2. Pull the bobbin case tab (A) and remove the bobbin case. Hold the bobbin case with one hand.

3. Insert the bobbin so that the thread runs in a clockwise direction (arrow).

4/5. Pull the thread into the slit and under the tension spring.

6. Hold the bobbin case between the index finger and thumb on the bobbin case tab (A).

7. Insert it into the shuttle race.

Bringing up the lower thread

Reduce the thread tension (3). (lower number)

Thread tension

Upper thread tension (A)

Basic upper thread tension setting: "AUTO" To increase the tension, turn the dial to the next higher number. To reduce the tension, turn the dial to the next lower number.
1. Normal thread tension
2. Upper thread tension too loose
3. Upper thread tension too tight

Note: The upper thread tension must be set at 2-3 when sewing the lightweight fabrics, like silk and jersey etc.

Unterfadenspannung (B)

Note: The bobbin tension is adjusted correctly during manufacturing, therefore no changes are necessary.

To test the bobbin thread tension, the full bobbin is placed in the bobbin case. The bobbin case and gripper are then suspended by the end of the thread. If the tension is correct, the thread will unwind by about 5 to 10 cm. when gently swung and will then remain suspended. If the full bobbin case unwinds, the tension is too slack. If the tension is too tight, it hardly unwinds or does not unwind at all. To adjust, use the small screwdriver.

Use a larger needle.

Matching the needle, fabric and thread

NEEDLE, FABRIC, THREAD SELECTION GUIDE

Important: Match needle size to thread size and weight of fabric.

Please Note:

• In general, fine threads and needles are used for sewing fine fabrics, and thicker threads are used for sewing heavy fabrics.
• Always test thread and needle size on a small piece of fabric which will be used for actual sewing.
• Use the same thread for needle and bobbin.
• Use the stabilizer material for fine or stretchy fabrics, and select the correct presser foot.
• The upper thread tension must be set at 2-3 when sewing the lightweight fabrics, like silk and jersey etc.

Remove and reinsert the needle. (flat side towards the back)

Inserting the needle

Important: Turn power switch to off ("O").

Change the needles regularly, especially at the first signs of problems when sewing.

Insert the needle as in the illustration.
A. Loosen the needle clamp screw and tighten again after inserting the new needle.
B. FThe flat side of the shaft should be towards the back.
C/D. Insert the needle up to the stop at the end of the shaft.

Only use fully-functional needles.
Problems can occur with the use of:
- Bent needles
- Blunt needles
- Damaged points

Remove the bobbin and unwind the thread.

Threading the upper thread

Important: Set the main switch (20) to ("O"). Raise the presser foot bar by lifting the two-step presser foot lifter (18) and lift the thread lever (1) by turning the hand wheel (21) anti-clockwise. Follow the arrows and numbers on the sewing machine when threading.

1. Place the spool (n) on the spool pin (15) and hold it in place with a spool pin cap (s).
- Small spool pin cap for thin threads
- Large spool pin cap for thick threads

2. Guide the upper thread through the upper thread guide (16) and bobbin thread guide (2) from right to left, then move it forward into the right slot and guide it downwards.

3. Guide it to the left under the guide lug (A) and then upwards again.

4. Guide the thread from right to left through the thread lever (1) and then downwards.

5. Guide the thread first behind the large, metal thread guide (B) and then through the eye of the needle. Always thread the needle from the front.

Needle threader

You can use the needle threader (g) as a threading aid.
1. Insert the needle threader (g) through the eye of the needle from back to front.
2. Guide the upper thread through the wire loop of the needle threader.
3. Pull the needle threader (g) together with the thread back through the eye of the needle.

Replace the needle.
