After continuous use for an hour, my vacuum pump is very hot, what should I do?

Pls turn off the motor before irreversible damage is happening. Wait until the motor has cooled down sufficiently and then start again. Do not let the pump run for long times without vacuum building up.

There's a lot of oil mist coming out of the oil cap lately, what should I do?

a. Don't run overload. b. Don't pump atmosphere. c. Use proper vacuum oil. Add oil to middle of tank scale. d. Exchange oil that is cloudy or discolored or smells like solvents once a month.

What should I do if there is noise during use?

Pls check whether the impeller of the pump is firmly installed. If the impeller is loose, it may cause noise when rotate and hit the edge of the impeller cover during the use of the pump. Pls re-install it firmly.

Rated ultimate vacuum of 5 Pa is bogus, actually is about 40 Pa

Seems to work, rated ultimate vacuum of 5 Pa is completely bogus, I measure about 300 microns with a new Testo 552 digital vacuum gauge, which is about 40 Pa. For most uses, 300 microns is probably sufficient. The price is certainly attractive, don't know about how it might last. Mine was part of a kit with a 3 gallon glass top chamber.
