Open the oil inlet and fill the pump with pump oil as provided approximately up to the middle of the level glass.[Note] Never fill any other oil than the one exclusively used for vacuum pumps. Also, be careful not to fill the oilexcessively.2. After filling oil, close the oil inlet. For change oil, high-performance TA117-1 to 3 manufactured by TASCO is recommended regardless of highor low temperature.[Gas ballast valve]Oil deterioration caused by moisture and condensable gas absorption into the pump oil can be prevented by operating withthe gas ballast valve opened and letting dry air flow into the pump.(Oil cleaning operation)Close the suction port valve of the connected manifold and operate with the gas ballast valve opened for 5 to 10 minutes,then the oil temperature will rise and vaporize moisture and condensable gas absorbed in the pump oil which is thus purified.Please perform normal vacuuming operation with the gas ballast valve closed.
