THREAD TENSION ADJUSTMENT
5-1 How to adjust the overedging seams
Thread tension adjustment will differ ac­
cording to the type of cloth, thickness, and
thread being used.
Adjust the tension using the upper and lower
thread tension adjusters while watching the
seams. (Figure 34)
Thread tension may be increased by turning
in a clockwise direction.
(1) When the tension of the lower thread is
too heavy (Figure 35), loosen the lower
overedging thread tension adjuster.
(2) When the tension of the upper thread is
too heavy (Figure 36), loosen the upper
overedging thread tension adjuster.
When the stitching seams appear as
shown in Figure 37, the tensions are
satisfactory.
(A) When the tension of the lower thread is too heavy.
