Hopefully someone can help,
We bought a bunch of machines at an auction and ended up with a Mazak HTC-400. With Covid and all going on, the machine sat out in the warehouse for several months. Upon powering it up, as we feared the batteries went dead. The issue now, is we don't have any of the manuals to go with the machine to re-set the home positions. Can anyone here help me with that information? I do have a copy of the parameters with the electrical schematic but looks like those are still ok. Haven't done this on a horizontal and due to some rough use over the years, I don't see any indicator arrows on any of the way covers to get me close.

Thanks in advance.
