By purging, you mean working out the air bubbles? From what I can tell from the Hydro Gear manual, you just have to run it for a little bit to work out the bubbles. If this is true, surely they would have worked themselves out, right?
Hydralic pressure will blast a hole thru steel over time..like a mini blowtorch..
If the pump was started dry..irreparable damage occurs in less than 10 seconds..
