The first thing you need to do before turning it on is to change the oil. These types of pumps cause the input to come in contact with the oil, so
the oil is likely quite wet. Avoid running the pump with wet oil. The water can cause corrosion to various parts of the vacuum pump over extended
periods of time and thus cause it to malfunction. After changing the oil, I would run the pump for a while then change the oil again to remove any
water remaining in the pump. |
