-３. Adjusting the thread take-up spring 

The standard position of the thread take-up spring (1) is 6-8 
mm [4-6 mm for -[][]5 specifications] above the surface of the 
thread guide (3) when the presser foot (2) is lowered. 
1.  Lower the presser foot (2). 
2.  Loosen the set screw (4). 
3. Turn the thread tension bracket (5) to adjust the spring

The standard tension of the thread take-up spring (1) varies 
in accordance with the machine specifications as shown in 
the table.

-[][]5 specifications 

0.30 - 0.5N 

 
1.  Push the needle thread with your finger until it is slightly 

higher than the thread tension bracket (5) and so that the 
upper thread is not pulled out. 

2.   Pull the upper thread down until the thread take-up spring 

(1) is at the same height as the base of the thread guide 
(3), and then measure the tension of the thread take-up 
spring (1). 

3.  Insert a screwdriver into the slot of the tension stud (6), 

and turn the screwdriver to adjust the tension of the 
thread take-up spring (1). 

 

NOTE: If using the tension gauge (7) (sold separately) to 

measure the tension, take the reading from the scale 
on the side of the red line.
