This is my second year plowing. Last year I bought a 97 f350 xlt with a fisher minute mount plow. It is the first model of minute mount. My pump is under my hood. When I went to hook it up all functions of the plow controls are extremely slow and delayed. How do I go about maybe bleeding the system? Or can I just top of the reservoir? Thanks in advance . I'm in N.H. and gonna be plowing tonight.
