It started as just a routine machine test by Rob, but it ended up being a whole lot more important!
He quickly discovered a significant number of blocked claw air admission holes, some even took a bit of scraping with a screwdriver to find the air admission hole!
From previous experience, he knew that in this particular setup, when the clusters hang between cows, some washing water always ends up flowing over the area where the air admission hole is, and the muck settles there.
The short term fix is to have the cups on operator wipe that part of the claw with their thumb as part of their routine.
