Troubleshooting
Step 8 Try to turn the handwheel clockwise until the
blockade is undone. Use considerable force if
required.
If this doesn‘t work, contact your BERNINA dealer.
Step 9 Remove bobbin, cutting the thread if required.
Step 10 Carefully remove any thread remnants with twee-
zers. If threads jam, slowly continue to turn hand-
wheel clockwise, pulling the threads out as soon as
they come free.
Step 11 Bring the hook in the pictured position (see on the
left) by turning the handwheel clockwise for correct
threading.
Step 12 Insert bobbin.
Step 13 Check the lower thread tension (see on the left) by
comparing the position of the lug with the figure in
the bobbin door.
Step 14 Swing hook in completely by turning the
handwheel counterclockwise, then close bobbin
door.
Step 15 Check the needle. If it is flawless, re-attach it. If is
not, use a new needle.
Step 16 Connect the foot controller again.
Step 17 Confirm messages «Manual mode for trouble-
shooting» and «Main motor is not running» or
«Check hook system».
