discomfort at the tool.

Note: When choosing hydraulic uid, the expected oil temperature extremes that will be experienced in service determine the most
suitable temperature viscosity characteristics. Hydraulic uids with a viscosity index over 140 will meet the requirements over a wide
range of operating temperatures.
