Fast Download,all pages present,an excellent copy.THis enabled to find the origional part numbers and chase them up. The cartridge is proving difficult to find but at least I know the origional part number.Thanks to all.
Very good manual, in depth and complete. Only criticism is that some of the circuit diagrams are slightly blurry and hard to follow for long periods of time, but this is to be expected. Perfect for any maintenance required. Also contains the wiring diagrams of the control cable for constructing extensions.
