Polar 115x hydraulic filter problem

[bram2000]

Hi,

We have Polar Mohr 115x cutting machine. We got error message :
Change the hydraulic filter.

We have changged the filter, and also changed the hydraulic oil (it's near 6000 hours). But the error message is still appear. At the monitor (the error message) we can see POTITION of the filter is RIGHT-BEHIND the machine. But actually the potition of the filter is RIGHT-INFRONT of the machine, BELOW the table.

Any body has the same problem ? Any solution ?

Thank you.
