  • Page 9: Cautions For Safety In Use

    ・Cautions for Safety in Use Danger Applications (1) This pump is not designed to be explosion-proof, and should therefore not be used to discharge explosive gases. (2) Not be used with toxic gases. In addition to discharge of gas via the outlet, gas may also leak from other parts of the pump, and it should therefore not be used with toxic gases.
  • Page 10 Warning Operation (12) This pump is not designed to be explosion-proof. When using the pump, ensure that there are no inflammable materials such as solvents, or explosive gases, in the vicinity. Use under such conditions may result in injury or fire. (13) Inserting fingers or objects into the pump inlet may result in electric shock, injury, or fire.
  • Page 11 Caution (4) Do not hold or push the tube at the top of the pump (see below). Damage to the tube may affect performance of the pump. DA-121D series DA-241S series Operation (5) Touching rotating components (e.g. motor, main shaft, axial joints, cooling fan) while the pump is in operation may result in injury.
  • Page 12 Note Installation (1) The pump may malfunction if it is subjected to shocks or tipped over on its side. Applications (2) This pump is not designed to be corrosion-proof. Use it only with clean air at normal temperature, or with gases of equivalent characteristics. (3) This pump is designed solely for vacuum extraction.
