    What is the proper way to change the fluid on a Fisher MM2?

    Set the plow on something, dolly or wood, so it is easy to angle by hand. Concrete isn't bad with an extra set of hands. Make sure the lift is all the way down. Pull the drain plug and fill plug. Once drained, unhook the angle hoses from the pump. Put hoses in something to catch the fluid and manually angle the plow fully left and right. now would be a good time to change the filter as well, 4 small bolts hold the resevoir on.

    Hook everything back up and put the drain plug back in. Fill so the fluid is just to the bottom of the fill hole. Lift the plow and angle fully left and right. Drop the plow and check the fluid level. I do that two or three times to make sure air is out of the system.

    It wouldn't hurt to drop the reservoir can and change the filter too.

    filter

    Where exactly is this filter located? I just replaced the electric motor, I assume the filter is in the pump end of the housing?

    It is. Like I said, there are 4 small bolts that hold the resevoir in. Be careful with those small bolts. I broke one the other day tightening them.
