Threading the bobbin

–

Place the full bobbin in the bobbin housing top, whereby the bobbin

has to turn in anti-clockwise direction when the hook threader is

pulled.

–

Pass the hook thread through the slit 6 and under the spring.

–

Dependent on chosen buttonhole the hook thread has to go

through slit 9 for raised-form buttonholes and slit 10 for flat-form

buttonholes.

Setting the hook thread tension

–

Set the hook thread tension by turning screw 12 so that the bobbin

housing slowly sinks with its own weight when the hook thread is

held tight.

–

Flat-form buttonholes will require a higher tension.

Fitting of bobbin housing

–

Put the bobbin housing top along with the bobbin on the bobbin

housing bottom, make sure that the clip 5 audibly snaps into place.

–

Close bobbin case lid.
