Threading the Looper Thread with an auxiliary thread

Threader.
Prerequisite:
• (see page53)
> Open the Threader Cover.
> Set the Air Threader Connector to the «left position».
> Prepare an auxiliary thread at a length of about 60 cm.
> Fold the auxiliary thread in half, hold the thread end with the loop in your hand and position the two
thread ends above the respective Air Threader Nozzle.
> Start the Air Threader Process until the thread ends of the auxiliary thread emerge out of the Looper Eye.
> Place the Looper Thread end at the length of about 20 cm through the loop of the auxiliary thread.
> Pull the auyiliary thread ends until the thread comes out of the Looper Eye.
> Remove the auxiliary thread.
> Place the Looper Thread under the presser foot to the back left.

The supplied Threading Wire can be used as a threading aid for the Looper Thread. The Threading Wire is a
wear part and not designed as a permanent threading or cleaning aid.
