The pump is stopped when the lord is operated, and the pump can’t be operated just after that.
In this case, please return the atmospheric pressure the inside of the pump.
２
The pump will not often operate normally if it is used with corrosive gases, organic solvents, liquids, or condensed gases (eg steam).
The pump will not often operate normally if it is used with gases containing particles or dust etc.
３
