    looking for a bit of help pretty sure i have a fisher mm1 (2plug)on a 2000 f250sd i just picked up. the left and right angle control is backwards meaning when i push control left it goes right and right it goes left. i have a mounted control box not a fishstik, i am thinking the control box might be the cause but not sure. also wondering if there is a downloadable set up guide for these someplace? as the the lift seems to lift high but the plow seems to still be somewhat low to the ground. any help or a point in the right direction would be great thanks

    unbolt the two ends of the chain and bolt the ends back up a few lengths higher then it was that should help the plow raise more.

    Sounds like there could be a wire crossed up somewhere or it could simply be the hoses on your plow are backwards. Personally I'd just switch the hoses because I hate trying to figure out wiring. As far as the lift height, just make sure you leave enough slack in the chain to let the plow float. Lift your plow and see how much room there is between the a frame and the headgear then take out the corresponding number of links in your chain. Hope that helps

    thanks for the replys got the height adjusted good and the hoses were backwards back in business with proper left and right angles on the control box.
