2) Adjustment of looper thread tension
[ Warning ]
Be sure to turn the power switch off before adjusting tension.
As a standard, the center of the thread hole of the looper
thread guide ② and ③ is generally positioned along the line
of the looper thread guide bracket①.
Loosen the screw to lower the looper thread guide down to
decrease the looper thread tension, and raise it up to increase
the tension.
※ When using the woolly thread, bring the looper thread
guide(②, ③) down as much as possible, and do not
insert thread into disc ④.
