Page 29: Stopping And Disassembly
The operating machine output pressure and flow rate must always conform to the requirements of the attachment in use (see 4.3. Technical Specifications). If this is not possible, the system must be equipped with reduction valves (contact the manufacturer of the operating machine or a specialized workshop). Do not use the attachment without check that the pressure and oil flow of the operating machine are those required. -
Page 30: Using The Attachment
