hitachi 120 MAINTANCE

[wilddanz71]

I recently bought a used hitachi ex 120-2 excavator with 4400 hrs
this weekend I changed all fluids and filters.
My question is, what is the regular intervals that I should change things??
I am new to excavators, so I need to learn there regular maintnense.
I can not buy a service manual, so Im told because it is a"Gray Market" machine. This service, I changed engine oil and filters, air filters,fuel filter, all the hydralic filters and changed fluid in the final drives. Should I change these every time I service??

thanks DAN

500hours on engine oil 6.6 gals engine oil. swing gear box 1000hours. travel gearbox 2000hours. hydraulic oil is 1500hours using Hitachi Oil, 500 hours change hydraulic tank filter, 500 hours change pilot filter, fuel filter is 500 hours as well. Can give a complete print out of intervals if wanted.

Sorry for going off topic but u sure about the hours on that machine.? I think that model came out around 1992-3. That less than 300hrs a year.

Reuben, I also have faced a virtual wall in my attempts to lay my hands on a workshop manual for my EX120-2. Any assistance forthcoming would be greatly appreciated.

I got rid of a 120-2 last year and it had just under 4500 hours

Yes the hours are correct!!! that is why I bought it. It was owned for several years by a small local excavation company, which I know personaly. I was told it is a 93 or 94. It is in great shape.
