Hi everyone, my leather sewing machine is Seiko lsc 8bv, and now there are some problems that i can't solve. Firstly, the official instructions show that max stitch length… 1/4″ (6.2 mm). But, when i set the stitch length to 6mm(the max), when actually sewing, the actual stitch length is only 5mm. How can I repair it to make the actual stitch length consistent with the setting stitch length? Where do i need repairs? Where is the part that needs repairing on the machine?Could you please take a picture so I can see where the problem is? Thanks in advance, Yelong Ma

I'm really sorry, maybe I didn't express it clearly. I want to ask what is the difference between 3BL and 8BL? Any details? I want to sew thick leather or canvas.

Hi, sorry, but I didn't understand what you meant

Hi all, I recently wanted to buy a leather sewing machine, there is a store near me that is selling seiko sth 3bl, I want to buy it, but I can only find information on seiko sth 8bl online. Does anyone know seiko sth 3bl? thanks
