Flushing

Flushing is performed to forcefully remove foreign particles from oil lines after hydraulic parts are replaced. Bypass valves are opened fully to permit circulation of oil through entire circuit system, thereby removing foreign particles from oil into filters built into reservoir tank, multivalve unit and pressure control.
