I bought a used juki DDL-8500 and i am having difficulties to adjust the stiches which are being made by it. i will b grateful if u can attach a manual for the sewing together with your reply.

Hi there
you can go to www.juki .com
under industerial sewing machine youy can download DDL 8700 instruction manual it's same DDL8300 model.
now you can do next steps
1- change needle with new one.
2- you can find tow mark on needle bar the upper mark for adjusting the hight of needle bar bring the needle bar at lower position and check if the upper mark aqual with the lower bushing or no.
3- when the lower mark aqual with the lower bushing at this time the blad point of hook must be at the center of groove for the needle if no lose tow screw for the hook and readjust the timming between the blad point for the hook and grove for needle bar
