The tension release mechanism operates during thread trimming. 
When the lifting lever (1) is lowered and the distance <a> for the plunger (3) of the solenoid (2) becomes 6 to 7 mm, the 
tension discs begin to loosen. Carry out adjustment by the following procedure. 
 
1.  Remove all of the parts shown in Figure A. (Keep them removed while adjustment is being carried out.) 
2.  Lower the lifting lever (1). 
3.  Adjust the tension release connecting rod (4) and the crimping pin of the tension release plate (5) so that the distance <b> 

is 0.2 to 1.0 mm. 

*  Loosen the two set screws (6), and move the lever (7) to adjust distance <b>. 

(It is easier to adjust if you touch the tension release connecting rod (4) against the crimping pin and then adjust to the 
distance shown in the illustration.) 

4.  While gently pushing the lever (7) toward the rear, tighten the two set screws (6). 
5. Push in the plunger (3) of the solenoid (2) to the position shown in the illustration, and check the tension release start 

timing.
