Threading the Looper Thread with an Auxiliary Thread

If a looper thread cannot be threaded automatically with the air threader, the use of an auxiliary thread makes sense.

    Prerequisite:

  1. Threading is prepared.
  1. Open the threader cover.
  2. Move the air threader connector to the left.
  3. Slowly turn the handwheel counterclockwise until the air threader pipes couple.
  4. Prepare an auxiliary thread at a length of about 60 cm.
  5. 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.
  6. Start the air threader process until the thread ends of the auxiliary thread emerge out of the looper eye.
  7. Place the looper thread end at the length of about 20 cm through the loop of the auxiliary thread.
  8. Pull the auxiliary thread ends until the thread exits the looper eye.
  9. Remove the auxiliary thread.
  10. Place the looper thread under the presser foot to the rear left.
