1. Read here that people complain about lack of oil. it came with a lot of oil. filled it in. Then I read that it burned down. Well, before you start, you need to fill in the oil. I then had a problem when the suction reached the maximum the pump could handle and when I closed the valve on the suction hose the vacuum started leaking air. beat. I fixed everything and the suction power drops and the system stays in vacuum. I don't leave it running any longer than necessary, then turn it off and turn off the faucet. This is very much. I use it to degas silicone mixture.
