The Upholstery Forum

A friend gave me a juki 8300N that for sure needs some work. Most of it I can probably do myself, however it looks like the presser foot pressure button broke off and can’t be screwed out. Is it worth getting fixed?

What do you plan to use it for?
While it is an industrial machine, it appears to be light to medium material. Not heavy material such as upholstery materials.

A quick Google search showed that the Leatherworks.net had a posting answer from Wizcrafts that said amoung other things the following:
The 8300N is a very high speed tailoring machine. It uses thin thread, has weak tension springs suited to cotton or polyester garment thread, has a fine tooth 4 row feed dog, and prefers to be run at about 91 stitches per second - to distribute the oil from the sump pump to the ends of the wicks. It will sew about 1/4 inch of cloth, using system DBx1 needles, ending at number 18. The thread handling limit would be no more than B69.
In other words no it's not a suitable machine for sewing upholstery or heavier material.

The last sentence was my comment not part of what Wizcrafts posted.
