Jack A4F Industrial Electronic Lockstitch Sewing Machine
This Jack A4Fis a computerized lockstitch machine.
The upgraded and more advanced model of the regular A4.
Jack has adopted a German design when manufacturing this machine, this gives it clear lines, sharp edges, and corners making it much more professional looking.
This machine has been developed to ensure user-friendly and easy use. Some key functions that have been adapted into this machine are precise stitch length, short remaining thread, and many other functions.
The manual reverse lever has been removed from the face of the machine and has been installed by the needle so that sewing is easier. Also, the electrical display on the machine ensures precise options, such as Baratack, auto-thread cut, and others that can all be easily adjusted.
The baratack and reverse feature are completely silent on this machine, there are no loud clicking or banging noises.
