The issue started when I took my gun out after it had been sitting a few days. It had been functioning perfectly up until this point. The bottle gauge read 20 bar. It had been at 210 bar when I last put it away. I took the bottle off and immediately the bottle began degassing until it was empty. I removed the bottle valve and took it apart. There were no damaged o-rings but there was some dark colored lube coating some areas inside the valve. Strange. I wondered how it had got in there. I removed the o-rings to clean them and where they were seated. Cleaned everything up. Lightly lubed the o-rings with silicone oil. Put the valve on the bottle, screwed on the bottle, it gassed up to 100 bar. I unscrewed the bottle and no degassing occurred. Great.
Screwed the bottle back on. Bottle gauge read 100 bar, but the first reg read 50 bar. I've always kept the first reg at 200 bar, so it should be at 100bar as well. I removed the bottle to confirm that the first reg screw was set the number of turns that it always has been. It was.
So I removed the first reg and took it apart. There was a little of that dark-gray colored lube on the surfaces inside. I cleaned it up, but could find nothing wrong with the o-rings, washers, no obvious blocks over the tiny holes. The plunger surfaces looked flawless. I disassembled everything, cleaned, added fresh silicone oil on the o-rings. Restacked the bellville washes just as they had been before. Reattached 1st reg. Screwed on the bottle and the bottle gauge went to 100 bar but the 1st reg gauge rapidly bounced between 50 and 80 bar for about 2 seconds, settling at 50 bar.
Don’t know what to do at this point. Maybe one of the little holes in the reg has some of that strange dark grey lube or other debris clogging it? If so, how would I clean out such a tiny hole?
Let me know if anyone has any ideas.
Thanks guys.
