    My cylinders on my 7.5' Fisher SD seam to "give" to easy. It doesn't take much to make it relieve pressure. So I was wandering if you can some how adjust the amount of pressure it takes before the pressure relief "kicks in"?

    I don't know if you can adjust it ,but I'd rather have the blade turn when I hit something than blow a hose or bend something.

    There are 2 check valves on the side of the Insta act pump. One for each angle piston. They can be adjusted or may need to be replaced. If that doesn't work you may need to replace the angle pistons.

    Thanks for the advice. The plow is not even two years old so the angle pistons should be all good.
