I'm trying to troubleshoot what is going on with a 2012 580SN WT, it is having a rough time starting. Recently changed the fuel filter and I've been advised to check the injector lines for a possible air lock. I am looking for the service manual if anyone happens to have one or have any advice on how to proceed. Thanks!
On my 2012 590SN there is a bleeder screw just above the fuel filter. Just above the water separator there is a hand pump. with the tractor off open the bleed screw above the fuel filter and pump the hand pump until fuel comes out.
