    Ok so I am new to whole hydraulics thing and you may recall that I purchased a X728 w/ a 45 loader earlier in the summer (that a few of you helped me with a hydraulic leak earlier). Seeing this post on oil injections concerns me and I have a couple questions. Is it ok to check the lines by hand with the machine shut off and with the pressure relieved from the lines? Also, to relieve the pressure from the lines I just jiggle the loader levers once the machine is shut off, correct?
    Thanks guys, trying to be safe!

    Yes that would be fine. Looking for leaks after the system is been relieved with your hands is ok. You can use a piece of cardboard to put near a suspected area when the machine is running. And yes, to relieve the system pressure all you have to do is move the loader joystick in a few circles.

    Test:

    Say your using the loader and have a bucket full of rocks rasied up about 3-4 feet. You notice a "fog" or "mist" in the air so you shut the tractor off to investigate without lowering the FEL, you start feeling around the lines to look for a leak, could you have fluid injected into your hand?

    All of the hydraulics would need to be at rest. The loader needs to be lowered (this would of course happen when the joystick was moved around if the loader was not resting.), the 3PH needs to be fully lowered, and any additional hydraulic accessory needs to be relieved or at rest.

    Excellent point Kenny.
