2.6 Winding the hook thread
The external winder makes it possible to wind the hook threads
independent of the sewing operation.
–
Remove remaining thread from the bobbin hubs before winding.
–
Put the thread reel on the thread reel holder.
–
Thread the thread through the drill-hole 1 of the unwinding arm
(see picture on the left).
–
Guide the thread through guide 4.
–
Guide the thread through the bobbin thread tension 2.
–
Prewind the thread to the right in the front and back reserve
grooves of the bobbin hub.
The full reserve grooves guarantee a secure winding, even with
monofilament threads.
With the thread reserves in the reserve grooves the pocket opening
can safely be finished after the remaining thread monitor has
indicated that the bobbin is empty.
The reflecting surface 5 of the bobbin hub is to be kept clean.
–
Press the bobbin retainer 3 against the bobbin hub.
The winder starts.
After reaching the set bobbin filling level the winder shuts off
automatically.
See Service Instructions for setting the bobbin filling level.
