I've noticed that my harbor freight lift tank I use to move my pins slowly sinks. Has anyone had any experience with this? I've checked the release cable, it doesn't seem to be causing any tension.

This has had the problem from the moment I got it this past summer. The odd part is that sometimes it seems like the problem goes away, then it returns.

Does anyone know how to bleed it?

My instructions that came with the table were a folded piece of paper that made reference to bleeding the system, but with no specific instructions (at least in English). Do you know how they deal with the fact that if you raise it fully, then lower it half way, it's sinking on you while you pop the red plug? Sounds like a cat juggling procedure.

Ok, I ordered some hydraulic fluid and we'll get this guy fixed. Do I need a pump or special funnel to get it in, or just pour?

I checked my cable, it's not too tight.
