Direct-drive, 1-needle, Unison-feed, Lockstitch Machine with Vertical-axis Large Hook
LU-2810S-7/CP180
High and long arm has been adopted.
The long distance from the machine arm to the needle contributes to improved workability.
The LU-2810 Series is a unison-feed,
lockstitch machine with a vertical-axis large hook
which is provided with substantially
improved functions and performance.

Adjustable screw
Dramatically advanced availability for material
Mechanisms have been designed taking maintainability and
environmental friendliness into consideration.
The sewing machine provided with a thread trimmer has adopted a
high-torque direct-drive motor which is suitable for heavy-weight
materials. As a result, the sewing machine is excellent at its
responsiveness and ensures increased penetration into the material
even when sewing multi-layered parts.
High-torque direct-drive motor is installed. New-type tank style automatic lubrication mechanism has been adopted.Easy to find remaining oil quantity
LU-2810S-7/CP180
The direct-drive motor system has been adopted by all of the sewing machines with a
thread trimmer. As a result, the sewing machine starts up swiftly and promises increased
stop accuracy, thereby demonstrating improved responsiveness. In addition, the machine
is no longer provided with a V-belt. This means that the adoption of the direct-drive motor
is also effective in the elimination of belt shavings. Power is directly transmitted from the
motor to the sewing machine, thereby contributing to reduced power consumption. (This
sewing machine reduces power consumption by 37% as compared with the conventional
models.) Adoption of a direct-driven main shaft and a revamping of mechanism design
contribute to remarkably reduced noise. Noise has been reduced by 3.5dB as compared
with the conventional model to produce this operator-friendly machine.
JUKI ECO PRODUCTS
The LU-2810-7 is an eco-friendly product which complies with JUKI ECO PRODUCTS standards for protecting the environment.

Functions for improving seam quality and workability.
The long distance from the machine arm to the needle contributes
to improved workability
Thread tightness can be kept same, even the multi-level of material.
The oil dropped from the hook and its
surrounding sections into the under-cover is
filtered to remove dirt and dust and is then
returned to the oil tank. This method saves the
effort of oiling and reduces oil consumption.
The remaining oil quantity indicator is provided
on the front face of the machine head.
Lubrication can be carried out without tilting the
machine head.
Single or Double can be set easy through
Multi-functional 6-string switch, regarding the
machine with trimmer.(Available for more thick
material)
Double tension provided as : standard
Adjustment of the eccentricity of the feed
driving cam has been enabled. As a
result, the sewing machine is able to
perform sewing with the feed that is
best-suited to the material and thread
used. It is no longer necessary to prepare
other subclass model sewing machines.

In addition to the one-touch type reverse feed
switch, a multi-functional 6-string switch is also
provided. Changeover of the amount of the
alternating vertical movement of the walking foot
and the presser foot and changeover of the stitch
length can be done simply with this one switch.

Eccentricity of the feed driving
cam is adjustable.
The sewing machine with a thread
trimmer is provided as standard with a
2-pitch dial. One unit of this sewing
machine is able to sew different sewing
lengths since the sewing length can be
instantaneously changed over.
Stitch length can be changed
over among different lengths.
The sewing machine has adopted a feed
mechanism which keeps the ratio between the
amount of the vertical movement of the walking
foot and that of the presser foot constant even
when the material is changed. The amount of the
alternating vertical movement of the walking foot
and the presser foot is 9 mm at the maximum.
This amount can be set with ease by means of the
large dial installed on the upper section of the
sewing machine.

A presser bar height of 20 mm is
achieved when using the automatic
presser bar lifting lever. Thanks to this
feature, the process of joining leather and
heavy-weight sponges, which are usually
used as materials for expensive sofas,
can be carried out with ease.

Reduced by 37%
Power consumption
As compared with the conventional model, LU-2810-7 reduces noise by 3.5 dB.
This sewing machine reduces power consumption by 37% as compared with the conventional models.
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.
Lubrication system is powerful and stable
even low speed.
