    I was out plow is morning in a parking lot pushed up a pile then all the sudden no upward controls but left and right worked but slowly then after a couple secs after now nothing. The pump comes on but no hydrolic action. nothing works left, right, up, or the foot jack, fluid is full, if you run the pump with the fill cap off you can see fluid moving around. Is it a pressure relief valve and where would it be. There is 2 big bolt plugs on top of the valve block ones just a plug the other has a spring valve in it I just tapped the jack switch with it out and fluid poured out so I guess the pump is making pressure, and also read about freezing fluid def not that its not cold enough today. Any help is greatly appreciated

    Thanks. Yeah I looked there but I still cant find the pressure relief valve it not were it is in the pic. I took the pump off and started just pulling valves out and checking them so far all works as it should. but I did notice that is I hold the jack switch for a while it starts to make a lot of bubbles in the reservoir

    Sounds like air in the system. Check the line for the jack to see if it's tight (if there is a line; i know nothing about Curtis)

    Did you clean the screen on the pump. Usually this is the problem. They tend to get moisture in them.

    I think I might retire it next year due to the fact like u said no dealers around and hard to find parts

    Yeah but it was perfectly clean when I disassembled it. Wish I knew what it was

    That screen I think is multi layers. If you cleaned it, cleaned the tank and its working, that was it. Make shure the plug is clean, and the retainer pin is in plug.
