Well Got it back,gauge showed it was 3-4 full which means it had been filled as it was in the low scale when it was sent for a clean-out hopefully to solve charging problem, which reading between the line,s There was not a problem with Just tryed to fill it my self now at low part of green with my full 3 litre air bottle same problem as before theair goes everywhere but in the valve WHAT am I doing WRONG! I have changed the probe wonder if it is the spacer seals on the probe that slide down shaft to stop probe going in to far? The only part not replaced is the adapter on the air line from the tank that the probe plugs into, nothing wrong with line and bottle fills an AA s400 ok Anyone got any ideas please? As this could mean a long drive with rifle bottle etc to Wales for the Airgun repairer there to possibly go through my charging method to see what I am doing wrong.
