Loose stitches

Thread the machine correctly

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.

Inserting the bobbin

A. Upper thread tension

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.

B. Lower thread tension

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 1.97 to 3.94 inch. 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 screwdriver.

The bobbin case is not correctly threaded

Thread the bobbin case as illustrated.

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 (3) so that the thread runs in a clockwise direction (arrow). 4. Pull the thread into the slit and under the tension spring.

	5. Hold the bobbin case between the index finger and thumb on the bobbin case tab (A). 6. Insert it into the shuttle race.

Needle/ fabric/ thread combination is wrong

The needle size must suit the fabric and thread.

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.

Thread tension wrong

Correct the thread tension.
