Feed Dog Height.
The feed dog is normally adjusted for sewing fabrics of light and medium weight.
(1) When correctly adjusted, the feed dog rises just enough for the teeth to show their full length above
the throat plate.
If the feed dog height is not properly set adjust per the following steps.
(2) Loosen screw (1) and move the crank up or down as necessary.
(3) Tighten the screw and test the adjustment by hand-turning the balance wheel forward.
(4) A change in the height of the feed dog may throw the needle and feed dog out of time. Therefore,
check and adjust the timing of the feed dog and needle timing as necessary.
