There several user channels on YouTube that have videos.
This is mine, 15 yrs ago so the quality is somewhat wanting, with background noise from the camera's tape/recording mechanism. The full cycle is there, in five parts due to limitations of the at-the-time camera's recording duration. I added text overlays via a YT annotation feature to highlight various operational functions but YT eliminated the feature and the notations disappeared. Increase the playback speed to clearly see that the load rolls over while it rotates CCW through the recirculation shower.
