One of the most important factors when buying used machinery, especially when moving it is to make sure you get all documentation, I have lost track of the number of those that have purchased machinery at auction etc and did not get the documentation, which is often found on site.
If they are not available, download them ASAP.!
One day the machine's memory back up battery fails and there are no parameters and macro's to be re-loaded, the result is without them the machine is just a lump of iron and steel!
