How to test hydraulic preassure

mardi 1 mars 2016

I have a komatsu PC75uu -2 I am wondering where I can check my pressure. I have replaced my hydro filter and refilled the tank. I have noticed that the arms move slow and if I go up a hill the tracks will slow down and stop. The motor does not bog . I am trying to find where would be the best to test the pressure. Also what should. I have for pressure? Thank you in advance
