Good day
I have never seen or noted any manual reference to wheeled machine, my suggestion would be hunt for Samsung wheeled excavator manual. I know the wheeled machines in the EEC marketed by Volvo have been made in Germany. The machine you have would have been sold mainly in the Asian market. One possible English speaking would be Australian I am not aware of any in the USA, for sure if there is you will soon know on this site.
Sorry I cannot be more helpful.
