The standard angle for the feed dog (1) is for the top of the 
needle plate to be parallel with the top of the feed dog (1) 
(for the 8550A) or raised slightly at the side closest to the 
operator (for the 8560A) when the feed dog (1) is raised to 
its highest position above the needle plate. (With the     
mark on the feed bracket shaft (2) aligned with the mark on 
the feed rocker bracket arm (3)). 

1. Turn the machine pulley to move the feed dog (1) to its 

highest position above the needle plate. 

2.  Tilt back the machine head. 
3.  Loosen the set screw (4). 
4. Turn the feed bracket shaft (2) in the direction of the 

arrow within a range of 90º with respect to the standard 
position. 
•  In order to prevent puckering, lower the front of the 

feed dog (1). (Fig. A) 

•  In order to prevent the material from slipping, raise the 

front of the feed dog (1). (Fig. B) 

5.  Securely tighten the set screw (4). 

 

*  When the angle of the feed dog (1) is adjusted, the height 

and forward/back position of the feed dog (1) will also 
change and will need to be readjusted. 

 
 
 
 
 
 
 
 
 
 

Adjust the sideways clearances X between the feed dog (1) 

and the needle plate so that that are approximately equal. 

Adjust so that the clearances Y between the front and back 

of the feed dog (1) and the needle plate are approximately 
equal when the machine pulley is turned until the feed plate 
(2) is moved to its furthest forward position and also when it 
is moved to its furthest back position. 

 

Loosen the two screws (3) of the fed dog (1), and adjust the 

position of the feed dog (1). 

If adjustment is not possible using this method, adjust using 

the following method. 

 

Loosen the two screws (5) of the feed rocker bracket arm (4) 

and adjust the position of the feed dog.
