I recently purchased a used 2008 mini excavator John Deere 17ZTS, which is the same as the Hitachi EX17, from my local dealer. It has a button on the left side of the control console, that I can not figure out what it does.
When it is pushed a little green light comes on, but nothing else seems to happen.
This button is NOT in the operators manual, and the dealer does not know what it does, nor does the JD factory. They have said they will contact Japan to try to find out, but that it isn’t in any of their service books.
I believe it must be one of two things;
1) Some type of proportional load sensing hydraulics, that speeds up unloaded hydraulic functions - this was mentioned in some info I found while researching excavators.
2) Engine speed adjustment based on load, or automatic idle.
It only has about 4-6 weeks of the factory warrantee left, and need to find out if something is broken.
Besides this is driving me batty!
