SWITCHING STOP VALVE
Stop valves (1) at the arm top end are used to stop the flow of hydraulic oil. When installing and removing the
attachment, the stop valves must be switched to the stop position.
If the pressure still remains inside the piping, slowly loosen the subject hoses and connectors to release the
pressure inside the hydraulic piping.
