Brother Brother CP-6500 Thread tension, Correct tension, Upper tension is too tight

——————————————————————————————————————————————————————————————————————————————————————————————————————————————————————

Thread tension

The thread tension will affect the quality of your stitches. You may need to adjust it when you change fabric or thread.

Memo

●We recommend that you do a test sample on scrap of a fabric before you start to sew.

■Correct tension

Correct tension is important as too much or too little tension will weaken your seams or cause puckers on your fabric.

Memo

●When you finish sewing, remove the bobbin cover and then make sure that the thread is shown as below. If the thread is not shown as below, the thread is not inserted through the tension-adjusting spring of the bobbin case correctly. Reinsert the thread correctly. For details, refer to page 19, 20.
