    tried to get an answer to this on the newbie forum but got no response:

    I have an older Western (cable controlled) power pack that I'm trying to figure out if it's okay or not. after cycling the cylinders (all 3 of them) I sometimes want to look at the fluid level and so I unscrew the fill bolt. When i do this, fluid comes out under pressure. if i don't have a rag on top of the bolt, fluid shoots out everywhere. IS THIS NORMAL? is it normal for the power pack itself to build up pressure?

    it is normal .After every storm we check all levels in the trucks and some squirt the fluid ,others run out with the plug and some are fine. We have about 30 westerns both unimount and ultra mount.

    Your going to get stuff in the system no matter what you do. Air is going to increase the volume of fluid in the system with bubbles. Don't over fill it either.
