Check the hydraulic filter for fine metal/debris that would flag a component failure occurring. If clean the next step is to have your pressures tested. All other functions working? Check the steering cylinders for bypassing internally in the seals or a problem with the steering valve itself if confirmed supply oil and pressure is good. Let me know.

No hydraulic function sorry it was suppose to say that at the beginning no brake pressure no lift no tilt that is why I said I don't think the central valve is opening
Mechanic: Dan, Technician replied 7 months ago

Check the hydraulic filter for fine metal indicating a main pump failure.... Also inspect the relief valve cartridge in the main control valve for debris, damaged o rings, or other damage causing a bypass of pressure. Let me know

I have checked my filter found no metal particles I did find what looks like plastic or hard rubber pieces
Mechanic: Dan, Technician replied 6 months ago

That sounds like possible seal or o ring material. Check to see if any of that is causing the control valve spools to stick, etc.
