I will preface this post by telling you I am pretty green and NAA hydraulics. I just rebuilt my entire system from pump to lift cover. One thing I kept finding in all my research was how prone these NAAs are to valve sticking. It sounds to me that is your problem. I too had this issue, even after a full rebuild (taking every valve out and cleaning it, new ring, etc.) What I finally did was put a quart of ATF in my hydraulic chamber and let it run lifting the arms, lowering, lifting, etc. The detergent in the ATF worked and unstuck the valve, now my lift lowers as it supposed to and works just great.

Good luck,
Dan
