  • Page 174 USER MANUAL 914NG NNEXES SELECTION OF HYDRAULIC OIL Viscosity is one of the most important properties of hydraulic oils because it affects the hydraulic sealing and the functionality of the safety valves. Therefore the oil temperature is very important because even small changes in temperature affect viscosity: as the temperature increases, viscosity decreases.
