When the needle bar is at the top of its stroke
(needle position 2~3), there should be a distance of
approximately 9~9.5mm from the top surface of the
needle plate to the point of the needle.
Adjustment is made by loosening screws A.
< Note >
After the above adjustment is made, check to make
sure each needle drops correctly into the center of
each needle drop hole.
