    Hi all,

    I have an older mm1 and was trying to bleed some air out of the system. I have read that it is self bleeding but I don't see any vent cap or other areas for air to escapes when I move the rams back and forth with the lifting ram down. Any ideas? Below is a picture of the plow in question.

    It goes into the pump housing then comes out the cap when you fill it the second time.

    It also helps to hang the plow off a curb or something similar and angle back and forth a few times to get all the air out of the angle pistons.
