The looper passes behind the needle when it moves
from the extreme left end of its travel to the right.
When the point of the looper has reached the center of
the needle, the looper should be as close to the needle
as possible with no contact between the looper and the
needle. Adjustment is made by loosening screw K on
the looper holder. When the looper moves to the left
from the extreme right end of its travel while the
needle is descending to the back of the looper blade,
check to see if the needle touches slightly the back side
of the looper. If the needle is bent by the looper or
there is a clearance between the needle and the looper,
adjust the amount of looper front-to-back movement by
referring to the below.
