8.2 One-step BERNINA air threader
NOTICE
Damage by coated or waxed threads
Coated or waxed threads may lose some of their coating in the air threader pipes, resulting in permanent
blocking of the pipes. Repair by a BERNINA dealer will be necessary. Avoid use of coated or waxed threads.
The setting for the air threading is made by turning the air threader connection.
> Turn the air threader connection completely in the required direction.
Performing a pulse drive
A puls drive is a support function, allowing to move the main drive slowly while the covers are open. With
this function the main drive moves to threading position or the upper looper is activated/deactivated.
NOTICE
Pulse drive
If the air threader pipes are not coupled, the puls drive will be performed by pressing
the foot control.
The needles are brought into the top position and the coupling is complete.
Press the foot control again.
Threading or activating/deactivating upper looper can continue.
