Position of the presser foot

 

Loosen screw A.    Adjust by moving the presser foot 
left or right while checking to make sure the needle 
drops correctly to the center of the presser foot 
needle drop hole.

The presser foot should be 8.5mm above the top 
surface of the needle plate.

ADJUSTING THE STITCH FORMATION   

9-1 Position of the thread support 

 

 

When the needle bar is at the bottom of its stroke, 
the centers of the eyes on thread eyelet A should be 
level with the top surface of thread support B, and A 
should be parallel with B. 
Height adjustment of thread support B is made by 
loosening screw C and moving thread support B up 
or down.    Moving thread support B up tightens the 
needle thread.  Moving thread support B down 
loosens the needle thread.
