Consew 206RB - Regulating the Thread Tensions

Hold the bobbin between the thunib and forefinger of your right hand and
pull out a length of two or three inches of thread. Holding the bobbin
case in your left hand, turn the open side up and place the threaded
bobbin into it.
With the right hand guide the thread into the slot in the edge of the
bobbin case. Then pull the thread to the left, under the tension spring
and into the delivery eye. In order to heep the bobbin from dropping out
of the case when it is turned with the open side down, always keep the
hinged latch at the front of the bobbin case open (Figs. 4A, 4B and 4C).

stud "A" (Fig.5) of the bobbin case holder. Release latch and press

with a click that can be heard. Permit two to three inches of bobbin
thread to hand down freely. Be sure to push slide plate to the right
before starting to sew.

rotary hook. While the latch is held open,
the bobbin will be retained in the bobbin case.
Release of the latch and turning of the open
side of the bobbin case downward will cause
the bobbin to drop out.
