Thread tension:
Upper needle thread tension (Figure 1):
- For the best stitch
appearance and durability,
make sure the needle thread
tension is correctly adjusted.
For general sewing, the
threads evenly meet
between the two layers of
fabric
- The normal setting for utility
stitches is in the range 4-5.
- To increase the tension, turn
the dial to the next number
up.
- To reduce the tension, turn
the dial to the next number
down.
Figures:
A.Normal thread tension for
straight stitch sewing.
B. Thread tension is too loose
for straight stitch sewing.
Turn dial to higher number.
C. Thread tension is too tight
for straight stitch sewing. Turn dial to lower number.
D. Normal thread tension for zigzag and decorative sewing.
Note:
To obtain better zigzag and decorative stitches, the upper tension should be
slightly weaker than in the case of straight sewing, thus the upper thread appears
slightly on the bottom side of fabric.
Lower needle thread tension (Figure 2):
To check the bobbin thread tension , remove the bobbin case and bobbin and hold
it by suspending it by the .Jerk it once or twice. If the tension is correct, the bobbin
thread will unwind by about 2.5 to 5 cm downward.
- If the tension is too tight, turn the small screw on the bobbin case slightly counter-
clockwise.
- If the tension is too loose, turn the small screw on the bobbin case slightly
clockwise.
Note:
The bobbin thread tension does not normally have to be adjusted.
