NSM SERENADE STEREO MAGIC MANUAL

Hi everybody
I am new fellow on this forum but I have an NSM serenade in perfect condition since more that 10 years
Unfortunately the drives belts haves to be replaced.
I know where to buy the belts but I don’t know how to do it and when I have a look on my jukebox it looks necessary to remove several items to allow the belts replacement
Anybody have the manual maintenance who explains how to replace and adjust the belts?
Anybody have the full or partial maintenance manual with spare parts list (photocopies) for sold or gift

sorry but I am french fellow and all answer in English please
Best regards
