NOTE:

When choosing hydraulic fluid, the expected oil temperature extremes that will be experienced in service determine the

most suitable temperature viscosity characteristics. Hydraulic fluids with a viscosity index over 140 will meet the requirements over a wide range of operating temperatures.
