Hi, Would it be possible to send this to me too please? Also where are you getting the error code from? I have the same screen as in Barteks post above but it doesn't seem to be working. It's a machine I purchased recently to use on a self build.

Oh, thanks for the support. I've already solved the problem with this forum member. The thing was to cut the wire on a sensor that's attached to an arrow finger at its base. The key error was e50. In fact, there's still a lot of work to do, the excavator has been used for a long time without proper maintenance and even local fire survived, so far replaced all high pressure sleeves, absolutely everything.
