Oil stains on the sewing product are eliminated.
JUKI’s cutting-edge dry-head technology has been introduced to the MO-6700S, which has an established
reputation for its excellent seam quality and higher productivity.
Only the parts which mainly contribute to oil splashes are improved to have dry mechanisms to create the
semi-dry-head overlock machine, MO6700DA series. The MO-6700DA Series is the best selling machine
to eliminate oil stains on the sewing product.

●Oil splashes are substantially reduced to eliminate oil stains on sewing products, thereby upgrading the finished
quality.
●The frequency of stain removal or re-sewing is reduced.
●The machine achieves a practical maximum sewing speed of 7,000sti/min.
JUKI ECO PRODUCTS The MO-6700DA is an eco-friendly product which complies
with JUKI ECO PRODUCTS standards for protecting the environment.
●The needle bar mechanism and upper looper mechanism have been re-designed to require no lubrication.
●The most-advanced dry technologies, such as the special surface treatment applied to the major drive unit and
the grease feeding method, contribute to higher durability. The machine does not splash oil after a long-period of
use. The grease filler openings are newly provided for the sewing machine on two locations, i.e., one on the upper
looper component and the other on the sewing machine frame, thereby improving maintainability.
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.
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.

●The locus of feed and feed timing are selected to offer
optimum conditions for sewing light-weight materials.
●The machine comes as standard with a low-pressure
presser foot that is exclusively designed for
light-weight materials and is able to remarkably
handle small curves of the material. The presser foot
helps the operator control lighter-weight material
smoothly on the machine.
The sewing machine is fully equipped with adjusting
devices and provisions to effectively prevent puckering of
difficult-to-sew materials or new-generation materials.
The operator is able to produce beautifully finished high-
quality seams without conducting difficult adjustments.
●The feed mechanism feeds double chainstitch
looper thread with consistency, even under a low
tension. (Safety stitch machine)
