the right needle, the centerline
of the needle guard should have a
clearance of about 0-0.5mm between
the looper point and the right
needle. And it is also the same
clearance of 0 - 0.5mm between the
middle needle and the looper
point when the looper point is
in the rear of the centerline of
the middle needle.(Fig 32)

about 0 0.05mm, loosen the
screw (1), then move the needle
guard (2) back or forth.(Fig33)
2.When the needle is in below the
top of its lowest position, the
