6-3 Adjustment of the thread tension

The thread tension between the upper and bosom thread should be balanced in the best condition．
When the upper thread tension is well balanced with the bobbin thread tension，both threads are interlocked
along the centerline of fabric layers as shown on the below figures．
NOTE Normally weaker bobbin thread tension brings better sewing quality．
So it is prefer to set bobbin thread tension first and then set upper thread tension．

Adjust the bobbin thread tension with the thread tension adjusting screw
thread tension becomes loose if turn the thread tension adjusting screw
