Series

LZ-2280A Series is the latest model of highly-evaluated JUKI's zigzag stitch machines.

The sewing machine produces soft seams with consistency with
a low tension applied to the thread.

Problems which are associated with low-tension sewing such as "double-catching" and "irregular stitches", as well as factors which affect
seam quality such as "thread path", "thread bending resistance", "feed locus", "needle locus" and "timing" have been thoroughly reviewed,
thereby successfully producing soft seams. The machine has adopted JUKI's established genuine hook and thread take-up lever.

The lift of the presser foot has been increased and
the LED has been provided as standard

The visible area around the needle entry point has been increased and
the LED light has been installed, thereby helping reduce the operator's
fatigue when sewing small parts. The illuminance of the LED light can be
adjusted near the needle entry point.

JUKI ECO PRODUCTS standards for protecting the environment.

The sewing machine complies with the "Juki Group Green Procurement Guidelines" on the use of hazardous substances,
which is stricter than other restrictions, such as those of the RoHS Directive.

This sewing machine reduces power consumption by 8.6% as compared with the conventional models※.

For details of JUKI ECO PRODUCTS, refer to : http://www.juki.co.jp/eco_e/index.html

The RoHS Directive is an EU Directive limiting the use of 6 hazardous substances (lead, hexavalent chromium, mercury, cadmium, PBB and PBDE) in electrical and electronic equipment.
The Juki Green Procurement Guideline is the voluntarily established criteria to eliminate not only the aforementioned six substances, but also other ones which also adversely affect the environment.

Attachment-mounting seat

Installation of an attachment-mounting seat improves operability when
replacing the attachment and increases the durability of the machine
bed surface.

Maintenance

The adjustable range of the feed mechanisms
has been widened, thereby upgrading the machine's
responsiveness to materials

Inclination of the feed dog

Sewing direction

This-side-raisedposition

Level position

This-side-lowered position

The feed mechanism has been improved by widening the adjustable range of
the height and inclination of the feed dog. The feed locus has been optimized
while placing great emphasis on the feed locus at the moment the needle
penetrates the material to form a stitch. The weight of the feed mechanism has
been reduced by using parts most of which are made of aluminum material. This
facilitates sewing of overlapped sections of material that have to be securely
held between the presser foot and the feed dog during sewing.

Adjustment for various feed timings

Marker lines engraved on the face plate and
the pictorial indication facilitate adjustment of
the needle-to-feed timing and the hook timing.

Adjustment of oil quantity in the hook

Oil feeding path of the LZ-2280A Series has been reviewed to enable feeding of
consistent quantity of oil.
