Thread tension
Note:
Lower thread tension
Upper thread tension
The bobbin thread tension does not
normally have to be adjusted.
To test the bobbin thread tension, remove
the bobbin case and bobbin and hold it by
suspending it by the thread. Jerk it once or
twice. If the tension is correct, the thread will
unwind by about an inch or two. If the
tension is too tight, it does not unwind at all.
If the tension is too loose, it will drop too
much. To adjust, turn the small screw on the
side of the bobbin case.
Basic thread tension setting: "AUTO"
To increase the tension, turn the dial to the
next number up. To reduce the tension, turn
the dial to the next number down.
A. Normal thread tension
B. Upper thread tension too loose
C. Upper thread tension too tight
Bringing up the lower thread
Hold the upper thread with the left hand.
Turn the handwheel forwards until the
needle is raised.
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.
