It's a full manual. All the parts are in there. I haven't found the problem yett, but I am working on it; hope I can rebuild the part myself. To make it more secure and unbreakable this time. Because the part has failed several times before and costs a lot to let it be repaired.
Thanks so much for this rich illustrated and parted manual.

I downloaded the document. The manual was complete, well scanned and everything was legible. I could zoom in see what I needed to know. There's not much more that you can ask.

El manual esta muy detallado, los numeros de partes y los esquemas de despiece son correctísimos y muy claros, tanto para los técnicos experimentados como para los novatos.

Ottima qualità grafica e completo nelle notizie. Costo abbastanza contenuto.
