The basic pump will run hot and will smoke some as its burning oil but this is normal. Make sure that you check the oil level on your pump and make sure it’s never overfilled. All oil filled pumps will put out a mist while there is air moving through the pump. As soon as the chamber gets pulled down to full vacuum, the oil mist usually stops. If you are seeing an oil mist after 30 minutes or so, this usually means you have a leak in your system.
One thing to note...NEVER shut your pump off while it is under vacuum. Two things can happen. One, when you shut down with the pump under load, you trap some oil in the cycle. Then, the next time you start the pump it puts extra strain on a coupler that joins the motor to the pump itself. This coupler is designed to sheer under extra load to keep from damaging your motor. Repeated stress of starting the pump under load will cause that coupler to fail prematurely. It will also cause the pump to spit oil out the exhaust on the next startup many times.
It is always best practice to turn on the pump with all valves open and slowly close them. Then, leave the pump running the entire time you are stabilizing so that you are moving the maximum amount of air. Then, when you are done, open the valve and allow the pump to settle down. It will change noise. When the sound smooths out, shut off the pump. This will keep your pump running in good shape for years to come.
