Adjusting the bobbin case holding wire

Function

The bobbin case holding wire 6 holds the bobbin case top and bottom
parts in a certain position against the rotary motion of the hook.

The needle thread loop guided around the hook is pulled between the
springy holding wire 6 and the edge 5 of the bobbin case top part.
The holding wire 6 guarantees the unhindered passage of the thread
via the lug of the bobbin case bottom part and through the gap of the
throat plate.

Caution: Danger of injury !

Switch off the main switch.

Check and adjust the bobbin case holding wire only with the sewing
unit switched off.

Standard checking

Between the edge 1 of the holding lug and the edge of the throat plate
cutout there must be a thread passage slot of 0.6 mm to 1 mm.
In this position the edge 2 of the bobbin case top part is approximately
parallel to the throat plate.

The holding wire 6 must project from plate 8 by 13 mm and abut
precisely in front of edge 5 of the bobbin case top part 3.
–

Turn the bobbin case top part 3 against the holding wire 6 and
check the distance between the holding lug 1 and the throat plate
cutout.

–

Measure the length of the holding wire 6.
