Review on YaeTek 8CFM Dual Stage Rotary Vane Vacuum Pump (0.3Pa, 1HP) - Ideal for HVAC/Auto AC Refrigerant Recharging, Wine Degassing, Epoxy, Automatic Milking, Medical, Food Processing and MORE by Michael Hellewell

New out of the box, 3 control stamps on it. Filled with oil, read all the instructions, it is written that someone is obviously illiterate, sits and the pump hums, the assistant professor spins, the engine begins to overheat and stalls. When the device is off, I can feel electricity flowing through the suction port. literally shocks you by turning off the power. If left on it would surely start a fire. Drained the oil from the pump and put it back in the box. Came in clean and came out dirty. I don't know how to contact anyone about the warranty. DO NOT BUY FROM THIS COMPANY! Less than one star because I'm out of money now and have 3 customers in line. Manufactured and tested by the Chinese, that says it all. Garbage !
