KUKA Agilus KR10 R1100 HM-SC

Hi,

I have an agilus robot, the A4 servo brake failed. When replacing this motor, the oil in this axis drained out. does anyone on here know what spec of oil should go in this joint? Looking through the manuals, its not a serviced item so it is not specified.

Thanks

Thanks for the reply. Interesting, about 50mL of oil came out of the joint, while replacing the motor, the oil must have separated from the grease
