8100PP won't stay up?

    My 8100PP won't stay up. When plow is left in the up position it slowly lowers itself to the ground.
    Takes about 5 minutes. Any ideas would be appreciated.

    Debris in the valve or a bad valve.

    Bad valve?

    I live an hour away from the closest dealer. I tried cleaning the valve but it didn't help. I was hoping if it was the valve I could just order one and have it sent before the next storm.

    Check the lowering pressure adjustment at the left side of manifold. Adjust wheel in 1/4 " turns. Also remove valve and clean & replace and see if improvement.
