X-50 Woodworker x-axis oil port screw?

The Onefinity manual states that oil should be added to the oil ports of the ball screws periodically. Where is the x-axis oil port on the X-50 Woodworker? I can find the oil port screws for the y-axis but not for the x-axis. Can anyone help? [IMG_7788] [IMG_7789]
