4mm
when
the
Looper moves backward
at
the
farthest right position. Loosen
the
Nuts A and B,
and turn
the
Joint Rod C until
the
required distance is
obtained. After
the
adjustment, tighten
the
Nuts A and B
holding
the
Joint Rod C and keeping
the
above proper
distance.
Note: Make sure that
the
front face
of
the
Ball

not
in contact with
the
Oil
Drip Plate E finally.
Please notice
that
the
Nut A has left thread.

Loosen
the

tum
the
Screw
G as required.
Turning Screw G
to
the
right
will
make
the

it
to
the
left
will
make
the
Looper
get
nearer
to
you. After
the
adjustment, tighten
the
Screw
F,
and check
the
movement
of
the
Looper
again. {Fig.8)

point reaches
the
left edge
of
the
Needle. (Fig.

To
adjust, move
the
Needle Bar B
in
the
vertical
direction after loosening
the
Screw A
of
the
Needle
Bar
Connection. When
the
proper height is obtained, check
the
position
of
the

tighten
the
Screw A. {Fig8
