Start fresh. With the top up, disconnect the cylider rams from the top frame(1 bolt each side). Remove the plug from the pump and fill to just below the hole. Leave plug out and cycle the rams up and down several times. May take as many as 12-15 times. Keep an eye on the fluid level and fill as needed. Watch the lines for the air bubbles, you won't get them all out but you should be able to see mostly fluid running through them. Check the reservoir and fill to just below the hole again, NO more or you run the risk of blowing the center pump seal. Reinstall plug, reconnect rams, check top operation.
