In applications with rotary tables, the fluid pressure in the coupling will increase the table's starting-torque requirement and affect maximum rotation speed (see graph). All fluid-supply passages must be connected the power source, to ensure sufficient lubrication of the seals (do not turn the coupling while dry, even before installation). Use only with clean hydraulic fluid (10 micron or better nominal filtration). Use either standard hydraulic fluid (CLR-2-FL) or other hydraulic fluid of the viscosity classes HLP 22, 32, or 46. Allowable operating-temperature range is 50 to 140°F.
