LZ-2280N SERIES
The sewing machine produces soft seams with
consistency with a low tension applied to the
thread even when it runs at a high speed.
A market-proven titanium-finished hook and rotary thread
take-up lever have been adopted. This allows the machine to
produce high-quality and consistent seams when an extra low
tension is applied to the thread. The combination of the hook
and the thread take-up lever prevents stitch skipping and
thread breakage under the high-speed sewing and provides
responsiveness to thread changing. A broad range of thread
types such as synthetic thread, spun thread and cotton thread
can be used.
The highly reliable machine head is
structured to reduce operating noise and
prevent oil leakage
The shape of the machine frame is designed to reduce
vibration and noise during sewing. By applying three
safeguards in the machine's design, oil leakage is
completely eliminated. The shape of the machine arm is
designed to prevent oil from gathering, the direct oil-
circulation method is adopted to circulate the oil directly
from the oil sight window to the oil pan, and a high-quality
packing is incorporated. In addition, a bobbin thread winder
is built in at a position that permits easy bobbin winding.
The machine comes with a micro-lift
mechanism
Thanks to the micro-lift mechanism, the rise of the presser foot
can be finely adjusted using a screwdriver. This will prove
effective when you need to perform sewing operations with
the presser foot kept in a slightly raised position such as
when reinforcing the material or attaching tapes.
The adjustable range of the feed mechanisms
has been widened, thereby upgrading the
machine's responsiveness to materials
The feed mechanism has been improved by widening the
adjustable range of the height and inclination of the feed
dog. Inclination of the feed dog can be widely adjusted to a
this-side-raised position, level position, or this-side-lowered
position. This facilitates sewing of overlapped sections of
material that have to be securely held between the presser
foot and the feed dog during sewing.

The machine ensures easy adjustment of zigzag
width and feed pitch
A special dial with a built-in lever for adjusting zigzag width is
adopted for easier handling The machine is also provided with a lever
for changing the needle-throwing position that makes it convenient to
set the sewing position from the material edge. This enables the
operator to minutely adjust the needle-throwing position without re-
adjusting the positions of other components such as the guides and
binders. In addition, the machine is provided with a denser stitching
mechanism for fastening stitches.

Feed pitch for denser stitching is adjustable as
desired.
The feed pitch for denser stitching is adjustable as desired to enable
fine adjustments. The feed pitch only for denser stitching can be made
smaller solely by means of a knob. The feed pitch can be partially
made smaller during sewing.
