    8' X-Blade my pump stsrted tyo whine when it gets cold , so i was told there was water in the fluid, So i drained it removed the lines to the pistons to let the fluid out from there as well, Refilled with new Fisher hydrolic oil and it still screams i think even louder,???? can it be airbound. ? When I refilled the pump it was in a warm garage, and it didnt make any noise but as soon as it was outsde for an hour it started to whine, is there still water in there??? Help...

    Mine does the same thing when it's idle in very cold temperatures of zero or below.
    After I warm up the truck on these colder days, I've noticed if I rev the engine slightly while lifting the blade for the first time it doesn't make any noise. After I've used it some the noise stops.
