This manual is a complete guide, including later additions. It has all the necessary information about the replacement items. The material quality is great to read.
 ;
This manual is very helpful, correct shematic diagram, and good exploded view.Perfect!
;
Alte gescannte Servicepläne sind oft doch etwas undeutlich . Stromlaufpläne werden auf mehrere DIN A4 Seiten aufgeteilt. Alles ziemlich umständlich und zeitaufwendig. Aber mit etwas Mühe geht alles.
;
Great item, high resolution, detailed, very easy to work with.
