Thanks for the pictures. I did not get #5,6 or 7 from the first group.
The first picture is a position sensor. (It is used on wheel loaders too) With it tie where it is currently, that is telling the machine the stick is all the way out and will limit your lifting power.
The two pump compartment pictures show a normal group, I don't see anything I would not normally see on other machines.
The fourth picture is the location of the machine pump controller but, that does not look like the US versions. If you can find a part number on it, maybe that will point me to more on this attachment.
The first picture of the second group is showing the lock valve lines for the boom cylinders. This is seen on US machine as a safety option to hold loads on the boom without drifting. Often call "Anti-drift valves".
the second picture appears to show another box with a light on it, I have not see one located here on the US machine and I am not certain it is related to the boom system. A part number of this box may show me more on it too.
The third picture looks like a normal machine but, the fourth picture is much different from US machines.
It shows another "Anti-drift valve" on the stick cylinder and it will hold loads like the boom valve do.
However the hoses are not mounted to the side of the boom on US machines. This is only seen here on CR versions (Close Radius) which have not overhang on the back counterweight.
So, this does concern me that the ECM (controller box beside seat) is different and if it is the only one on the machine, you will not be able to remove it. Since you do have backup switches, you can use the machine in this mode as long as your monitor is still working and showing your gauges.
Although you may not have any engine oil pressure warning.
