    I have a Electric hydraulic Fisher MM1, I recently purchased a better moldboard and had disconnected one of my lines when attaching the moldboard. When I remove the fill screw the fluid comes gushing out, How do I go about adding more fluid to the pump with this issue? I have heard someone mention that there should be a vent that could be clogged, Where do I locate this vent? any help with be greatly appreciated.

    The vent should be somewhere on the reservoir and have a plastic cap that screws on. If there's air in the lines raise the plow, move left and right a few times, put plow into float, loosen foil cap slowly till air escapes. Repeat until there's no more air.

    Been awhile since I've seen a mm1 but I think its behind the motor.

    I actually just ended up taking the motor off and dumping in a half a quart and it seems much better now.
