    new mm2 will not raise,or angle

    Fist time poster here.. Hows it going guys

    Any ways i just bought a new fisher mm2 7 1/2 straight blade for my 1/2 ton had no problems with it yet just a few minutes ago i was plowing my driveway did a few backblades everything was working fine untill i made a pass down my driveway went to raise the plow and nothing happened...the plow would lower and thats about it every now and than it will angle a little but than nothing happens. when i press any button on the controller(left,right.up.down) i can hear the motor working it makes maybe a grinding noise kinda along with a single click... the last time i used it was about a week ago in negative 10 weather worked fine than.. i checked all my connections they all seem fine.. anyone advice on how i could fix this would be appreciated

    thank you,,

    I would be willing to bet you have a loose connection. Check the ground at the pump as well as the motor relay under the hood to insure all the connections are tight.

    I suppose I should first ask, did you get the HTS or the 7 1/2 HD. If you don't know, does it have a chain attached to the lift arm?

    sounds like ice or the pickup tube could have fallen off..

    Make sure you use fisher hydraulic fluid... some other brands freeze up easy. Also double and triple check grill connections

    yeah i wanna think (hope so) its just the fluid in the pump freezing up as i said earlier its been extremely cold when plowing its been in low teens temp..i am ignorant when it comes to plows really as this if my first one what color should the fluid be? i looked in the pump and it was a yellow ish color..i always thought it was black? ive seen fluid lines brake before on backhoes and such and it was always black

    if its brand new and you had it installed on the truck, go back to the dealer with it! Your not only paying to buy the plow and have it installed, you're also paying for the dealer support that should follow if something comes up! Good luck and let us know what you find.....i'm also guessing that you have the fishstik controller, it almost sounds like a circuit board problem, hard to believe on something new but who knows! Either way, if you bought it from and had it installed at a dealer, take the truck and plow to them! Be nice and courteous and it will go a long way.

    DITTO!!! BRING IT BACK!!! I cant imagine it is freezing up if it is brand new. I had a ezv that I would have to change the fluid twice a year because water would get in it and ice would plug the little filters. The pump would run and nothing would happen.

    andcon83 that sounds like what is happening to me.. i think moisture has gotten in there and blocked the filters.

    pickup tube as fallen off and the filter was pretty pluged up but i have one question... why is there a magnet on the bottom of the hydrolic reservoir?

    and also what would be the best way to clean the filter just to scrape out all the ice and such with a screw driver or can i spray it with air from a compressor..

    Can you put the plow in the garage so it can warm up? I would try to wipe it off with a rag, then maybe spray with Brake Clean. Make sure you wipe out the reservior to get all the water out.

    I'd like to know why he doesn't have blue fluid in his brand new pump.....

    Someone needs to tell those guys in Rockland that the yellow paint only goes on the plow, not in the pump......

    Fluid gets put in at the dealer. His dealer is the one that screwed up. Although, I bet FIsher wuld like to hear about that.
