Wanting to repair a neighbours tape recorder I needed the necessary information, it makes it easier. Although the service manual is described as "Language : English" To my dismay I found that it is entirely written in German, a language I do not understand. At least I now have the schematics which will help of sorts. I may not use this service again due to the laguage difficulty after all when it states English you do not expect it to be entirely in another language.
Good quality (clearly readable) manual, I'm glad I could find it here, at a bargain price!

REPAIRS REGARDING CD MECHANISM
IMPROVED METHOD - WHEN THE TRAY GEARS WERE DISTORTED
1. How to open the tray. In case of not suppling power push two hooks (H) of the base, and them open the tray. 2. How to improve the distorted gears. (1) Do the hole "C" of the cam gear to face forward the pick-up so the pick-up is down like figure. (2) Do the hole "B" of main gear to face forward pick-up, too. (3) Set the last part of main gear to point "A". (4) Push the tray to end.
