Note: None of the parts for new MO-6804 are interchangeable with prior model MO-6704, in case you already have MO-6704. Juki MO6804 is the newest model from a different Juki factory, so none of the parts are interchangeable with MO6704. Otherwise there are no differences in basic functions and capabilities between the two machines 3 thread machines. John

High-speed, Overlock MO-6800S Series
The MO-6800S Series responds to various kinds of sewing materials and processes, producing delicate and beautiful soft-to-the-touch seams while further reducing operating noise as well as increasing durability. This advanced overlock / safety stitch machine is easier to use and promises superior cost-effectiveness.responsiveness from light- to heavy-weight materials with a lower applied tension.

  • Since the machine comes with a needle-thread take-up mechanism as well as a looper thread take-up mechanism, to offer upgraded responsiveness from light- to heavy-weight materials with a lower applied tension, it achieves well-tensed soft-feeling seams that flexibly correspond to the elasticity of the material at the maximum sewing speed of 7,000rpm.
  • The newly adopted upper and lower needle bar bushings of the needle bar mechanism improve both the durability and reliability of the needle bar unit. The machine comes standard with a cartridge type oil filter and cooling fan for further improved reliability and durability.
  • Gauges and devices you have used with your existing JUKI machines are also interchangeable with no additional machining. This eliminates both the waste of resources and unwanted extra costs.Specifications
