I could sure use some help with this problem if anyone has experienced this, any help would be greatly appreciated, I have a EX60 about a 1991-1994 model. After you run it about 10 minutes, the hydraulic movements slow down. Does anyone know how much working hydraulic pressure this machine is supposed to have? Has anyone experienced this with their machine. Thanks Cadyman:beatsme :beatsme
If all functions go slow I would look at the Pilot Pressure although not usually a problem that would be the place to start. Should have a minimal 400psi. Put a guage in and watch it as your machine functions slow down.
I don't remember what type of pump is installed in those machines. Post a picture and I might be able to point you in the right direction.
