    Hooking up an inline gauge to the angle. As the manual says to push plow against a hard object.... I assume you need 2 people to do this. Anyone happen to have a solution for a solo test?

    Are you talking about the cross over valves? If so we use a hand pump to pump pressure back through the valves and see when the valves break open and adjust them, assuming you have the adjustable type. As for the pressure valve, with the valve in line extend the cylinder valve that has the gauge on it and check max pressure when it stops and then adjust it.

    Adjustable psi releif valve e-60. Its the adj nut on the side of the pa block. If I have a psi gauge in series with a hose on the angle couplers where/how do pump pressure into the pump?

    While having the psi gauge inline as above I tried to note pressure by raising lift but get little reading if any. I wanted to try an adaptor into the pressure port?

    Whoa Cowboy, you are talking about the crossover relief if it's on the PA block. If you want to adjust your main pressure relief the adjustment is on the top of the base and sump. Item number 40 in this drawing http://ww2.meyerproducts.com/upload/forms/1-663 R12.pdf instrutions for the placment of the gage can be found here http://ww2.meyerproducts.com/upload/forms/1-667 R7.pdf

    If you have a spare angle hose you can possibly use it between the T and the gauge so the gauge will be visible from the drivers seat. Then push the plow against something hard until the bypass valve opens and note the pressure... adjust and repeat.

    I may need to hook up 2 hoses. Hope that wouldn't reflect the psi

    religh valve

    we used to use a come along between the blade at the shoe mount and the pin attaching point ,to adjust the crossover relief valve .easier than hitting a wall or running a bunch of hoses .:waving:
