position.
Raising or Lowering the Feed Dog
The feed dog should show a full tooth above
the throat plate when at its highest position. To
adjust the dog, remove the throat plate and make
sure all lint, dirt, or other obstruction is removed,
then replace the throat plate. Turn the balance
wheel forward until the feed dog is at its highest
position; then loosen the feed dog adjusting screw
(2) (fig. 9-41), and raise or lower the feed dog as
required. Retighten the adjusting screw to hold
the feed dog in position.
To prevent the feed dog from striking either
end of the slots in the throat plate, loosen the
pinch screw (9) (fig. 9-41) and move the feed dogs
forward or backward (as necessary) until the
longest stitch can be taken without striking the
throat plate.
Sewing Techniques
In this chapter we pointed out the need to let
the machine feed the material being sewn, and
other techniques to obtain a good seam.
At first you will find it very difficult to
turn comers when using a sewing machine. If
you will follow these instructions you will find
it very easy to make a turn and not lose your
stitch.
Stop the machine while the needle is
rising, but before it is out of the mate-
rial, raise the presser foot and turn the
work. This method uses the needle as a
pivot. When the material lies in the new
position, lower the foot and continue sew-
ing.
Removing the Work
Raise the presser lifter and turn the machine
by the balance wheel until the take-up lever
is at its highest position. Draw the work
out away from you. If the threads do not
draw out easily, the take-up lever is not
in the right position. If the machine is stopped
as directed, the needle will not be unthreaded
when you start to sew, even if only a
short end is left through the eye of the
needle.
