Actually I think there is no extra service manual for BM3400. There is service manual for BM2000 (Type 2801) with extension for BM3400. This two devices share lot of their electronics, maybe you can use the manual for BM2000 for your issues (depends on parts which are fault).

I have this extended service manual but unfortunately not in electronic form.

If nobody here can provide you a good copy, please let me know. maybe I can find some time next week to scan and send it to you.

Best regards

Hello,

Thanks a lot for this quick answer.

I already serviced and restaured BM 2000's by using the corresponding service manual and Martin's kits. It was ok. 

I do not have unfortunately this 3400 extension and would be very happy to benefit.

Next week and the weeks after are OK I can wait. 

Best Regards

Alain

As I said I think there is no extra service manual for BM3400. At least I have in my manuals collection only this service manual for BM2000 (Type 2801) with extension for BM3400.

Alain got it, others who want to have a copy, please send me Mail.

Thanks a lot for having taken care.

This doc fits exactly what I was looking for.

Feel more comfortable to have a look to the 3400 unit.
