Problems With Hitachi Excavator

I'm having a problem with an Hitachi EX75 UR excavator.
1) It won't shut off by the key
2) the foot/handle throttle doesn't alter the speed. I have to increase the stepping motor to one to increase the speed.

Any suggestions?

Hello Hi ex 75,

Welcome to the site.

I've never owned Hitachi and your description doesn't trigger any immediate remedy to mind.

Where are you from Hi ex 75 ?

I hope to see you around often.

How did you get it to shut off? That sounds like your shut off solenoid is fouled up.

When you talk about speed do you mean engine speed or travel speed?
