4-1 ADJUSTMENT OF NEEDLE THREAD SENSOR CABLE 

The needle thread sensor cable effects the timing of both needle thread and
looper threads.  You are required to adjust this cable first.

NOTE: The needle thread sensor cable adjusting screw works; 

Turn clockwise and both needle & looper threads become loose. 

Turn counter-clockwise and both needle & looper threads become tight.

a) Line up the looper thread fine-tuning screw at the standard position.

b) Sew 1-layer of cotton with 1-needle (right) 3-thread as shown in the above 

and adjust only the needle thread in the stitch not to have a puckering. 

Disregard the looper threads in the stitch at this stage.

c) Then, adjust the looper thread sensor cable (4-2). 

4-2 ADJUSTMENT OF LOOPER THREAD SENSOR CABLE 

Before the adjustment of looper thread sensor cable, adjust the needle 

thread sensor cable first (4-1). 

NOTE: The looper thread sensor cable adjusting screw works; 

* Turn clockwise and looper threads become loose.   

* Turn counter-clockwise and looper threads become tight. 

a) Line up the looper thread fine-tuning screw at the standard position.

b) Sew 1-layer of cotton with 1-needle (right) 3-thread as shown in the previous page and turn the

screw until you get the ideal stitch which looper threads are not loose and fabric is not curled. 

c) After adjustment of looper thread sensor cable, the timing of needle thread

might be changed.  Therefore, check the needle thread sensor cable again (see 4-1).
