Wider space under the arm
JUKI has developed a new high-long arm machine head one size
larger than the head for the conventional lockstitch machine. With
its wider area under the arm, the machine permits easy handling of
the sewing material for improved operability. The shape of the
jaw gives the operator a clear view of the area around the needle.
Higher productivity
✱
In the standard zigzag stitching mode with the zigzag width set
to 4mm, a frequently selected operating condition, the machine
sews at a top speed of 5,000rpm, that is the world's highest
available speed as a computer-controlled zigzag stitching
machine, to increase in productivity.
(The dry-head type and the anti-material-slip type machines are excluded.)
The maximum zigzag width: 10mm
✱
A zigzag width of as large as 10mm is possible for all types of
stitch shapes.
Sewing troubles such as stitch skipping or thread breakage will
never occur even when sewing at the maximum zigzag width.
* A gauge that supports 10mm is required.
Attachment mounting seat
✱
The machine is structured without an oil pan. Oil is supplied
from the oil tank installed on the machine to the hook and
needle bar.
✱
In addition, the oil hole is located on the machine arm.
This is quite helpful to female operators; since oiling can be
carried out without tilting the machine head.
✱
Time and effort are conventionally required to remove the
knee lifter and cover. This means the machine head can be
easily tilted when cleaning the machine or performing
maintenance.
✱
A safety switch is mounted on the machine head. If the
machine is tilted with the power on, the safety switch is
activated and disables the machine operation.

depress the foot pedal.

Excellent maintainability.
Reduced noise and vibration
The machine comes with a more rigid and well-balanced
machine head frame. This, coupled with the direct-drive
method, dramatically reduces the noise and vibration of the
machine and helps reduce operator fatigue.
Increased feed amount
✱
Since the machine supports the feed amount as large as
5mm, this single machine is able to handle various feed
types from standard feed to coarse feed. The coarse feed
is effective when sewing stretched elastic tapes in
processes such as elastic tape attachment to waistbands in
shorts.
(For the anti-material-slip type machine, the maximum feed
amount is 2.5mm.)
✱
The stitch dial is a stepless adjustable type. This enables
fine adjustment of the feed amount.
