The machine offers outstanding
capabilities for the sewing of sports shoes
and leather shoes that require a wider
zigzag width. The zigzag width can be
quickly and easily adjusted by the dial
mounted on the front face of the machine.
To ensure smooth sewing of heavy
materials, the lift of the presser foot is
as high as 14 mm (1 mm for the LZH-
1290-7).
By reducing the frequency of bobbin
thread replacement, the newly introduced
horizontal-axis double-capacity hook
contributes to increased efficiency in
sewing. This feature is extremely helpful
when sewing with thick thread.

With its newly incorporated triangular cam, the machine uniformly
tenses thread in zigzag strokes regardless of the needle position,
and the needle always enters the material at right angles. This
prevents the needle from swaying during zigzag stitching.
Consistent sewing performance
at a high speed
The machine tenses thread uniformly over the zigzag stroke to produce beautifully finished
stitches at a high speed. With its extended zigzag width, higher presser foot lift, and newly
introduced horizontal-axis double-capacity hook, the machine upgrades the functions required
for the sewing of heavy materials. Equipped to handle a wider range of thread counts, the
machine also delivers improved abilities for the sewing of decorative stitches and overedging.
n addition, the AC servo motor/controller for the model with the automatic thread trimmer has
been fully reconfigured to provide higher motor power and quicker actuation, thereby ensuring
smooth operation.
The machine is optimally suited for the sewing of sports
shoes and leather shoes.

The machine is equipped as standard with
a one-touch reverse feed mechanism

The pneumatic auto-lifter comes in two different types: the knee-switch type (AK-112C) and the
pedal-switch type (AK-145 ). Select the type best suited for the applications of your machine.
1-needle, Lockstitch, Zigzag Stitching Machine
with Large Hook and Automatic Thread Trimmer
LZH-1290-7
The machine's unique
thread trimmer mechanism
allows the thread trimmer
to cut the thread when the
needle is either at the left
or right end of its zigzag
stroke. This mechanism
also eliminates the need for
adjustment even when the
thread count is changed.
The machine is equipped
as standard with a one-
touch reverse feed
mechanism. With just a
press of the touch-sensitive
button, the machine goes
into reverse feed stitching
mode. The touch-sensitive
button is mounted at a
position where it won't
interfere with sewing
works.
