Ouch. Ok, so it seems that the second part of the demo (flushing an empty pump) is actually from maintenance section of the manual (page 4) where it says to start the empty pump AND pour 1/3 cup oil into the intake port BUT it also says to just run it for 5 to 6 seconds. The manual doesn't say anything about covering the exhaust port with your hand though but it does make sense to do it. In the Flushing Oil sub-section of the Pump Maintenance section on page 2, it also says to repeat the procedure until the contamination is removed from the oil reservoir, pump rotors, vanes, and housing. Unfortunately, it doesn't say how to check that. All we have on the outside is the sight glass.
Grainger carries repair parts and kits at great prices.
This is how JB sell more vacuum pumps. Convince you to break yours.
I followed these instructions to a T on my platinum pump and it seized 10 min into my next vacuum
