Hi there everyone. I tried filling my hw100 with my hand pump but the air just seems to gather in the hose and stays in the pump. The pressure rises on the hand pump gauge but stays the same on the cylinder. I've pumped it up to about 230bar put the air won't go into the cylinder of the gun. I've cocked the gun, took the cylinder out and also emtied the cylinder in trying to pump it up but nothing.
When filling with a dive bottle it fills fine. It can easily pump up the kral jumbo also with a 200bar fill. Any ideas what might be wrong?
Any of you got a 3 or 4 stage pump they don't use? Lol
