MVD535

Any of you maybe can help me out to find the NAGOYA model DS 335 cylinder sewing industrial machine operarting PDF manual?. I just got this machine, and the local seller does not have any operating manual, actually yes, but in chinese language. I tried for days to find it in Google without success. My machine model and brand it is identical to the CHOICE brand model GC335A (both from China), so the manual of this one will be also useful for me. Many thanks for any help.

Hello CRFIREMECH, I know have been passed too many time since 2018, but I would like to try to contact you anyway because I am about to get the same buty you got, the 51W54. The one I want has the TIMING BELT broken, and after one month, I found here the 234003 P/N which I believe is the right part. This belt has 62 teeth cleats and it has 234003 P/N stamped on it. Could you confirm if this P/N is the correct one?, I appreciated very much in advance your answer.
