M3 2nd stage reg removal?

Got a leaky 2nd stage regulator. It's a pretty slow leak, about 10 bar per hour. Regardless, gotta fix her. There's approximately three million videos on Youtube on how to remove the 1st stage reg (front, where the bottle screws in), but I can't find instructions on how to remove the 2nd stage regulator. Can anybody point me in the right direction?
