If the pump is cold, run the pump with closed suction intake for 10 minutes to warm up the oil

Stop the pump and disconnect it from the mains

Open the oil drain valve and drain the oil completely into a container large enough to hold all the oil and tilt the pump slightly (if possible)

Close the oil drain valve and fill with new oil through the filler plug up to the middle of the oil sight glass. The oil level must not exceed the allowed maximum level

Wipe off eventual oil spills from the pump and/or the floor

Connect to mains again and verify correct rotation direction of the pump
