The tip of the rotary hook (3) should be aligned with the 
center of the needle (4) when the needle bar (1) moves up 
1.8 mm (2.2 mm for –[]03A and –[]05 specifications) from its 
lowest position to the position where reference line (b) is 
aligned with the lower edge of the needle bar bush (2) as 
shown in the illustration. (The distance from the upper edge 
of the needle hole to the rotary hook tip will be 0.5 to 0.7 mm 
at this time.)

 

 

1. Turn the machine pulley to raise the needle bar (1) from 

its lowest position until reference line (b) is aligned with 
the lower edge of the needle bar bush D (2) as shown in 
the illustration. 

2. Loosen the set screws (5), and then align the tip of the 

rotary hook (3) with the center of the needle (4). 
The distance between the tip of the rotary hook (3) and 
the needle (4) should be approximately 0 - 0.05 mm. 

3.  Securely tighten the set screws (5).
