At an initial operation or at an operation after a long rest, the pump may have difficulty in sucking up the fluid. In such cases, an air bleed valve should be installed beforehand on the discharge side (model No. ST1004-∗-10∗, catalogue No. Pub. EC-3001.), or discharge air by slightly slackening the connection on the discharge side. At starting, operate the pump intermittently as far as possible with no load. For fluid viscosity at starting, see the item of "Hydraulic Fluids".
