Never used the Aux since Ive had it, hooked up my 4 in 1 bucket to it this afternoon, hit the variable/max flow button for Aux, pulled trigger on right hand control and engine booged down but nothing, so played with the 3 switch's on the front, when i used middle toggle switch the pipe from the rear of the pump moves like its getting pressure, but nothing happens after. Traced pipes and found what i think is the two valve coils, one looked ok when i removed it, didn't remove the stem as no idea how but cleaned the shaft, the 2nd, more towards the front of the machine looked rusty, took it off and filled with rust inside, so ok could poss be that, gonna order a new one if i cant get it clean again. Dropped cab thought i'd give it one more quick toggle thru, selected the Aux button, worked them through again and nothing, the arms were raised a little so went to drop them and they raised. pulled trigger on right control again arms dropped ok, deselected the Aux button, engine bogged down again, lifted arms and tried to drop them again and again lifted, have to have the aux button selected to behave normally, Please for my sanity with this machine can someone shed some light on this for me before i take a few gallons of fuel and a match to it Thanks Jon</p></blockquote><p></p>
