TO REMOVE THE WORK
To remove the "·ork. raise the presser lifter; turn the
balance wheel from you until the pornt of the needle going down
reaches the presser foot. bringing the take-up le,·er to its highest
position. Draw the work from you until you can draw the
threads into the thread cutter. If the threads do not draw out
easily, the needle is not in position, as directed. If the machine
is stopped and held as directed, the needle will not unthread
when you start to sew if only a short end is left through the
needle.
For com·enience in taking out the work. the tension of the
upper thread is released "·hene,·er the presser lifter is raised;
but it is not released by the rising of the presser foot as thick
goods or seams pass under it.
Causes of the machine not working properly -..viii usually
be found in the tension not being correctly adjusted, or its discs
may be clogged with lint or knots of thread, or the thread may
be too coarse or too fine for the needle, or the needle and thread
too coarse or too fine for the throat plate. or the needle bent
or blunt. ee that a straight needle is pushed up in the needle
