 ;
Fast, clear and useful. Important for me: the manual is in German.
 ;
Very good quality. Some parts are not fully readable, but the fundamental ones are fine.
;
very good quality readable manual,printed off very well.
;
The manual was very accurate for the part that I was changing, I was able to order the correct part and had no issues with the replacement procedure. However, I was expecting to have more detailed repairs for the lower drive unit.
;
I needed the manual immediately and I got it immediately. I couldn't find this manual anywhere else on the net. The site was easy to traverse, and the price was very reasonable. I'll definitely be back for any future needs.
