The bobbin fills up during sewing.
If the machine is only run for bobbin winding (without sewing), a hook
base must be fitted in the hook.
Otherwise a jammed thread may damage the hook!
● The tension of the thread on bobbin 1 can be adjusted with knurled screw 4.
● The bobbin winder stops automatically when bobbin 1 is full.
If the thread is wound unevenly:
● Loosen nut 5.
● Turn thread guide 6 accordingly.
● Tighten nut 5..
