    Being a brand new unit I would expect there is some machining stuck in the DS rod end relief valve. Unfortunately on that unit you have to take the hydraulic unit off the plow and remove the plastic shroud to get at the relief valves. Sometime the dirt will just flush out after using it for a while but I would take it back for warranty service ASAP.

    Thanks I will be stopping in today or tomorrow..and for the record, Kerrs Equipment our western dealer in south east Michigan has been nothing but ease to deal with and great customer service when buying the plow.. Recommended to anyone.

    Did you try running through the procedure to get the air out of the system once or twice...
    ...Kind of like the IT department to restart your computer, but hey maybe it will work. (For those that have had to deal with IT departments.) :waving:

    ^^^^ This, we have seen several new plows come through with crap in the reliefs. Only we don't take the pump off. We drill holes in the cover then use rubber plugs to seal the holes off. Makes any future repairs much easier.

    We did that on a couple but one came back and bit us in the butt after the operator decided he would experiment with adjusting everything to try and fix a blown fuse problem. After that we stopped making the holes.

    Yes it was only a few months old, new operator, no mechanical aptitude at all. When the fuse blew in his new MVP+ (after the leaking check valve was fixed) it was going up when he hit right, angling when he hit up and so on. He tightened all the hose fittings, tightened every ORB plug he could see through the side covers and tried adjusting every screw he could see including the quill valve and the pressure relief valves, where we had made holes through the shroud. It was a mess, we had to check everything and of course it wasn't warranty. An expensive "don't touch what you don't understand" lesson.:laughing:

    Dealer over the phone mentioned the same thing about the air... Just seems like that wouldn't be it after working good for 8 hours on the first push and 6 hours into the second.. Haven't put the plow back on to mess with it yet but dealer said no matter what he will figure it out

    If the system is full of fluid the air will self purge after a few minutes of use. This is not an issue of air.

    Wouldn't think so but if the fluid level is low for some unknow reason it "could" make it go away... So check the oil level b4 and after running through the system air purge procedure. :blush2:

    And I agree it "shouldn't" be that but why not try...nothing to loose. :D

    Assuming not air, not garbage in the lines.... It would then be the values need adjusting. Mine was too soft and upon recheck with a proper pressure sensor it was obvious.

    There is something in the trouble shooting manual about how many turns to get close without a gauge. But if you don't know it wont' keep you from being stupid either payup
