This machine uses SINGER

 Class 15 transparent bobbins.  

Use only this style of bobbin when purchasing additional bobbins for your machine.  Do not substitute 

with metal bobbins.

1.  Place thread spool and corresponding size 

spool holder onto spool pin. Spool holder 

should be large enough to cover the end of the 

thread spool so thread unreels smoothly.  For 

smaller, narrower spools, use the small spool 

cap, which can be found in the removable 

storage compartment.

2.  (A) Snap thread into guide at top of machine.   

(B) Place thread snuggly around bobbin 

winding tension disk to ensure that thread 

winds onto bobbin smoothly and consistently.  

(C) Thread bobbin as shown, then place it onto 

the bobbin winding spindle.  

3.  Check that bobbin is pushed down firmly (A).  

If it is not, the thread could begin winding 

under the bobbin. Push the bobbin and spindle 

firmly to the right (B).

4.  Hold the thread end to get ready to wind.   

Step on the foot controller gently as you 

hold the thread end. Allow it to wind a few 

revolutions slowly, then remove your foot from 

the foot control to stop.

5.  Trim the thread end close to the top of the 

bobbin, then resume winding by stepping on 

the foot controller.

6.  The bobbin will stop winding when it is full. Lift 

your foot off the foot control. Push the bobbin 

to the left (A), then trim the thread and remove 

the bobbin from the spindle (B).
