I just picked up a meyers e60 pump, the guys said it has been sitting for a year in a heated shop. I got it all hooked up, changed fluids,filters and it lifted great but would leak down at a pretty fast rate. I used the plow too try and finish my driveway but now it no longer lifts up with pressure on it. If I remove the chain it lifts up great but, if I hop out and push down on the lifting ram it goes right down. I've also read possibly something too do with the A valve or the packing on the bottom of the ram. Let me know what you guys think!
