Mike E. has some good (yet sometimes overly long and divergent) videos on Hatsan rifles starting with the Mod95 and UP. I have looked in the past and have not yet found a good "full disassembly" Striker/Edge video anywhere on youtube. This thread and video have some good info on specific mods that make the Edge/Striker trigger MUCH better, but still lack the full disassembly steps requested. https://www.gatewaytoairguns.org/GTA/index.php?topic=167795.msg155926034#msg155926034If this is Ron's first time digging into a springer I understand why the details matter.First step before ANYTHING ELSE...Ron, Do you have a solid & safe SPRING COMPRESSOR?
...Nope. No spring compressor...Kinda thought gas rams didn't require one...(Shows what Ron knows....)I do have a 36" clamp, and pipe clamps up to 10' (I will let Ron use it...)
Since this appears to be your first springer just a reminder NOT to dry-fire it.
Hoping it doesn't leak again, but wouldn't bet money on it. Once o-ring seals are worn/deformed they usually get worse over time and replacement is the only solution.
