9. Upper Thread Adjustment 

 

A. Main thread adjustment device

 

 
The  tension  of  the  upper  thread  gets 
tighter if the tension adjusting nut (1) as in 
Fig.  16  is  turned  in  a  clockwise  direction 
and  it  gets  looser  when  turned  in  the 
opposite  direction.  The  tension  of  the 
thread  should  differ  according  to  the 
sewing  conditions  which  depend  on  the 
material, thread, stitch lenght etc.  

 

       Fig.16

 

 
 
B. Tension adjustment of thread take up lever spring

 

 
As in Fig 16, use a driver in the thread adjustment shaft groove (2) 
to adjust the spring tension. The thread take up lever spring grows 
tighter when the driver is turned clockwise and looser when turned 
counter clockwise. 

 

 

 

 

 

 

 

 

 

C. Auxiliary thread adjuster

 

 
Turn  the  auxiliary  thread  tension  adjusting  nut  (1)  in  clockwise 
direction to make the remaining thread lenght on the  needle after 
trimming  shorter  and  in  counterclockwise  direction  to  make  it  longer,  as  shown  in  Fig.17.  The 
appropriate lenght of the upper thread remaining after trimming is 30mm - 40mm.

D. Thread release control

 

 
The thread release takes place simultaneously with the movement of the trimming solenoid. As seen 
in Fig.24, the amount of thread release is controlled by moving the fixed position of the thread release 
wire (2), which is connected with the clutch lever (1), left and right. Loosen the two fixing nuts (3) and 
pull the cable wire (2) to the left. Then fasten the nuts (3) to release the thread to a large extent. If the 
cable  wire is  pushed  to  the  right  and  the  nuts  (3) tightened,  the  thread  release  happens  on  a  lesser 
scale.  After  adjustment,  tighten  the  nuts  (3)  once  agin  and  check  whether  the  opening  of  thethread 
guide plate (4) of the thread adjuster is about 05-1 mm when the thread releaser is in operation. There 
should be no opening when the thread releaser is not in operation. The thread guide plates (4) should 
be touching back to back.
