7.3 Threading the Looper Thread
At least one looper thread is required to form a stitch.
NOTICE
Damage by Coated or Waxed Threads
Coated or waxed threads may lose some of their coating in the air threader pipes. This results in permanent
blocking of the pipes. A repair by the authorized bernette dealer is required.
Detailed information can be found in the stitch chart.
Using the Air Threader
Prerequisite:
• Threading is prepared.
• Threader cover is opened.
> Set the air threader connector to the left position.
> Slowly turn the handwheel counterclockwise until the air threader pipes couple.
> Feed the thread through the thread guide.
> Pull off a thread reserve of approx. 56cm so that the thread can be completely drawn through the air
threader pipe.
