What you need

• *Overloader(1)
• *Birds(1)
• *Wire coils(3)

Steps

1. 1

   Turn your machine over

   Turn your machine to get better access to your sons

   
2. 2

   Bring your sons back

   Cut the left threads (those that are not assigned to your needles) right after the coil, place the new coil and tie the old and new thread, it must be solid so I recommend you make a double knot

   
3. 3

   Needle yarn

   Take off your needle thread completely, and replace it with your new thread, it will make the next step easier

   
4. 4

   Pull wires

   Pull your new sons right before the mechanisms, or after your needles, your son will pass through your guts thanks to the old thread already threaded

   
5. 5

   Run your machine

   Rotate your machine thanks to the wheel to form the first points, then serious to the pedal, and congratulations you managed to change the thread!
