    I am a bit frustrated with a fluid leak on my MM2 straight blade. I identified the fluid leak from the pressure relief valve screw, located just behind the cross relief valve screw. I went to the Fisher dealer and bought the valve kit with springs etc. I replaced the valve, lubricating the O rings, tightened screw all of the way in, then turned out 2 and a quarter turn as recommended by Fisher for safe operation. I then topped up with Fisher fluid, fired up the truck and the valve is still leaking.......ughhhhh. Has anyone had a similar issue? The dealer says that they have never heard of this in all of their years as a dealer. I Find that a bit interesting. As a result, I am at a stand still on ideas so any help would be greatly appreciated.
