i found the manuals for lots of there machines but not the one am looking at, although the company that service them said they would send me one if i cover the printing and postage. i think i found the manual for the bosh controller but am fairly sure i will have to replace the full gubbins

Am going to have a look at one of these on monday/tuesday, am guessing that it will need a full refit , but if the beds not bent and the rails guides are ok, i will give it a go.
