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

The maximum permissible case pressure specified in the data sheet must not beexceeded. Use of the axial piston unit in explosive environments unless the component ormachine/system has been certified as compliant with the ATEX Directive 2014/34/EU Use of the axial piston unit in a corrosive atmosphere Use of the axial piston unit in aircraft or spacecraft2.4 Personnel qualificationsThe activities described in this manual require a basic understanding of mechanics,electricity and hydraulics, as well as familiarity with associated technical terms.For transporting and handling the product, additional familiarity with the use oflifting devices and lifting accessories is required. In order to ensure safe use, theseactivities should only be performed by skilled personnel or an instructed personunder the direction and supervision of skilled personnel.Skilled personnel refers to persons who possess the professional training,knowledge and experience, as well as the understanding of the regulations relevantto the work to be done that are necessary to recognize possible hazards and takethe appropriate safety measures. Skilled personnel must follow the rules relevant totheir field and have the necessary hydraulics expert knowledge.Expertise in hydraulics includes: Being able to read and fully understand hydraulic circuit diagrams In particular, fully understanding the relationships with regard to safety devices Understanding how hydraulic components work and are put together.Bosch Rexroth offers training support for specialized fields.

Safety instructions11/602.5 General safety instructions Observe applicable accident prevention and environmental protection regulations. Observe the safety regulations of the country in which the product is used/operated. Use Rexroth products only when they are in good working order. Observe all notices on the product. Do not install, operate, remove or maintain Rexroth products if under the influenceof alcohol, drugs or medication that may affect your reaction time. Only use genuine Rexroth accessories and spare parts to ensure there is no risk topersonnel from unsuitable spare parts. Observe the technical data and ambient conditions specified in the productdocumentation. If unsuitable products are installed or used in applications that are of relevance tosafety, unexpected operating conditions may occur in the application, which couldresult in personal injury or property damage. For this reason, only use the productin safety-relevant applications if this use is expressly indicated and approved inthe product documentation, e.g., in explosion protection applications or in safetyrelated parts of a control system (functional safety). Only commission the product if it has been determined that the end product(e.g., machinery or system) in which the Rexroth products are installed complieswith the country-specific provisions, safety regulations and standards for theapplication. Use tools appropriate for the work being performed and wear appropriateprotective clothing to prevent punctures and cuts (e.g. when removing protectivecovers, disassembly). There is a risk of entanglement when operating the axial piston unit with a bareshaft end. Check whether or not your machine requires additional safety measuresfor your application. If necessary, make sure these are properly implemented. Depending on the type of control used, electromagnetic effects can be producedwhen using solenoids. The use of the direct current (DC) on the electromagnetdoes not produce any electromagnetic interference (EMI), nor is the electromagnetinfluenced by EMI. Potential electromagnetic interference (EMI) exists if thesolenoid is energized with a modulated direct current (e.g. PWM signal). Themachine manufacturer should conduct appropriate tests and take appropriatemeasures to ensure that other components or operators (e.g. with a pacemaker)are not affected by this potentiality.RE 92701-01-B/04.2018, A10VO, A10VSO Series 31, Bosch Rexroth AG
12/60Safety instructions2.6 Product-specific safety instructionsThe following safety instructions apply to chapters 6 to 14.WARNINGDanger from excessive pressure!Risk of death or injury, or property damage!Improperly changing the factory pressure settings can result in a pressure increasebeyond the max. permissible pressure.Operating the unit above the max. permissible pressure can cause components toburst and hydraulic fluid to escape under high pressure. Changes to the factory settings may only be made by Bosch Rexroth specialists. In addition, a pressure relief valve is required in the hydraulic system as a backup. If the axial piston unit is equipped with a pressure cut-off and/or pressurecontroller, this is not an adequate safeguard against pressure overload.Danger from suspended loads!Risk of death or injury, or property damage!Improper transportation may cause the axial piston unit to fall down and lead toinjury, e.g. crushing or fracture, or damage to the product. Make sure that the load bearing capacity of the lifting device is sufficient tosafely bear the weight of the axial piston unit. Never stand or reach under suspended loads. Make sure the unit remains stable during transport. Wear your personal protective equipment (e.g. safety goggles, safety gloves,suitable working clothes, safety shoes). Use suitable lifting devices for transportation. Observe the prescribed position of the lifting strap. Observe the national laws and regulations on occupational health and safety,and transportation.System/machine under pressure!Risk of death or serious injury when working on unsecured machines/systems!Risk of property damage! Switch off the entire system and secure it against reactivation according to theparameters provided by the machine/system manufacturer. Make sure all relevant components in the hydraulic system are depressurized.Follow the machine/system manufacturer's specifications. Note that the hydraulic system may still may be under pressure even after thepressure supply itself has been disconnected. Do not disconnect any line connections, ports or components as long as thehydraulic system is under pressure.Bosch Rexroth AG, A10VO, A10VSO Series 31, RE 92701-01-B/04.2018
