Threading the twin needle

that both threads are placed underneath the bobbin winder
thread guide. During threading in the left threading slot,
make sure that you pass one thread to the left and one
thread to the right sides of the tension disk (B). Continue
threading in the usual manner, making sure the threads do
not become twisted together.
Pull the right thread into the right thread guide and thread
the right needle. Pull the left thread into the left thread gui-
de and thread the left needle.
It is not possible to use the automatic needle threader with
a twin needle.
