Hello good morning. I...

Hello good morning. I have a Komatsu pc220-8 it’s a grey market machine. It seems as if my swing break will not disengage. I’m wondering if you have a wiring diagram so I can use to start troubleshooting?

Mechanic's Assistant: Hi. What is the complete model and serial number of your machine?

Pc220-8 but the Chinese we bought it from took off the serial number not sure why

Mechanic's Assistant: Is there anything else the Construction Mechanic should know before I connect you? Rest assured that they'll be able to help you.

It’s a grey market machine bought in China

These gray market machines are almost impossible to get schematics for. If you look at the swing brake, you will see lines coming off of it. If you trace those back to their origin, there wi be a solenoid valve there. Make sure that coil is getting power when swing is activated.  If it is not, check all fuses. It may take a bit to trace it all out. In my system when I punch in your serial number,  it is not recognized due to being gray market.

And you are very welcome.
