4.10.1
Using this special construction, the height of the needle can be adjusted. This
device proves to be quite useful when using different needle thicknesses. The
height of the needle can be adjusted by turning the eccentric (6), which features
a groove, that is located on the front side of the needle bar head. Make sure
that the needle of any thickness passes over the feed cup with a gap of about
0.1 mm in the area between the point and the eye of the needle. After
loosening the screw (5) of the needle setting plate (4) and then adjusting the
height of the needle, the screw (5) has to be tightened again.
