Water in the hydraulic oil (milky oil)

Milky oil means water has entered the hydraulic system. Act fast: water destroys hydraulic pumps.

Safety first: Switch off the pump, release all pressure (open the on/off valve or bleed-down valve) and lock out before you open any high-pressure part. Never put a hand or tool near a running jet.
