Hi, I have a used Hitachi ZX85US. The last owner bought a Brand new idle speed controller before the handover, but now, I got the same problem... The machine is running on full speed (probably because the brakedown of the idle speed controller happend when I was digging with the machine...) I can not adjust the speed manually.... I can not turn of the machine, Unless I pull the wire under the seat.... Have someone got a clue why this is happening? Is there a pressure sensor that controls the input to the controller? Otherwise, the machine is working great! 9000h 2005-model BR John / Norway
