Safety instructions9/602 Safety instructions2.1 About this chapterThe axial piston unit has been manufactured to generally accepted engineeringstandards. There is still, however, a risk of personal injury or property damage if thischapter and the safety instructions in this documentation are not observed. Read this documentation completely and thoroughly before working with the axialpiston unit. Keep it in a location where it is accessible to all users at all times. Always include the required documentation when you pass the axial piston uniton to third parties.2.2 Intended useAxial piston units are hydraulic components, meaning that in their applicationarea they are classified neither as complete nor as partly completed machinery asdefined in the EC Machinery Directive 2006/42/EC. The component is exclusivelyintended to form partly completed machinery or complete machinery together withother components. The component should only be commissioned after it has beeninstalled in the machine/system for which it is intended and the safety of the entiresystem has been established in accordance with the Machinery Directive.This product is intended for the following use:The axial piston unit is only approved as a pump for hydrostatic drives in an opencircuit. Observe the technical data, application and operating conditions andperformance limits as specified in data sheet 92701 and 92711 and in the orderconfirmation. Information about approved hydraulic fluids can be found in datasheet 92701 and 92711.The axial piston unit is only intended for commercial use and not for private use.Intended use includes having fully read and understood this manual, especiallychapter 2 “Safety instructions” on page 9.2.3 Improper useAny use other than that described as intended use is considered improper.Bosch Rexroth AG is not liable for damages resulting from improper use. The user issolely responsible for any risks arising from improper use.The following foreseeable misuses are also considered improper (this list is notexhaustive): Use outside the operating parameters approved in the data sheet or in the orderconfirmation (unless specifically approved by the customer) Use of non-approved fluids, e.g. water or polyurethane components Changes to factory settings by unauthorized persons Use of assembled parts (e.g. attachment filter, control unit, valves) other than thespecified Rexroth components Use of the axial piston unit with assembled parts under water at a depth ofmore than 10 meters without the necessary additional measures, e.g. pressureequalization. Units with electrical components (e.g. sensors) generally cannotRE 92701-01-B/04.2018, A10VO, A10VSO Series 31, Bosch Rexroth AG
