After threading, make a trial sewing.
Be sure to use a double layer of fabric in order to check whether the
seam and thread tension are adequate.
1. Set all of the thread tension dials at “4”.
2. Make sure that the upper knife is lowered (in the cutting posi-
tion).
3. Raise the presser foot.
4. Place the fabric under the presser foot.
5. Lower the presser foot and sew.
6. At the end of the seam, continue sewing to form a 5 to 6 cm long
thread chain.
7. Holding the fabric with one hand, pull the thread chain over the
thread cutter on the presser foot shank.

Turning to the right increases the thread tension.
Turning to the left decreases the thread tension.
When using filament thread or woolly nylon thread, adjust the
thread tension accordingly.
