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.
Lower thread tension (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 (m).
Hold the end of the upper thread with the
left hand. Turn the handwheel (21) in the
anticlockwise direction until the needle is
again raised (a complete revolution).
Pull on the upper thread to bring the lower
thread up through the stitch plate hole. Lay
both threads to the back under the presser
foot.
