Hello and Good Morning!!!!

I picked up an old EDM for small projects.

Cleaned the tanks. Added Filters, new fluid and scales.
Power it up, everything is functioning in manual.
In AUTO, push START, the ram retracts all the way up.

And starts hunting down from the top position.

EDM Technology, NY, 1990.
Tank says OMEGA 405b

Any info or help would be greatly appreciated.
The guys at Arrow, sent me to EDM-ZAP & EDM Network, I'm just waiting for replies from the last 2.
