Hey I have a 763 the is flashing up wiith the HF1-2 error under full load i read the manual it says high restriction on the first filter. whats the cause for this? and how can i fix the problem?

could be a bad sensor , but if you are using 10w30 in the hydraulic tank I have seen if you change the oil to a hydraulic oil it will most of the time take care of that problem , but I have also seen a bunch of 753 and 763 that are plauged with the hydraulic filter code and changing the sensor doesn't fix the problem
