As a general guide only, the user can achieve the correct
tension for normal sewing, by carefully suspending the
wound bobbin ,n Its case by the thread. If the bobbin
loose rT r""' too
oose and should be increased. The correct tension is
obtained when a slight jerk of the thread causes the bobbin
to drop a short distance only. If this action does not move
the bobbin the tension is too tight and should be loosened
until the desired effect is achieved.
