11RE 07008General product informationHydraulicsBosch Rexroth AG5/322Scope of delivery and responsibilitiesInstallation of Rexroth hydraulic products in a machine or system may increase this value, and if so, the manufacturer of themachine/system must document this.2.1Scope of delivery and responsibilities ofBosch RexrothAt or above 85 dB(A), the plant operator must make suitablehearing protection available to the personnel.1Rexroth hydraulic products fulfil all safety requirements applicable to fluid power systems and their components.IMPORTANTFor the scope of delivery and the responsibilities ofBosch Rexroth with respect to the product, please refer to theProduct-specific Operating Instructions.2.2Responsibilities of the plant operatorCAUTIONIf Rexroth hydraulic products are positioned in the vicinityof sources of ignition or strong radiators of heat, protection must be put in place that would prevent any escapingpressure fluid from igniting and the hose lines from agingprematurely.Mineral-oil-based pressure fluid is hazardous to water andflammable. It may only be used if the relevant safety datasheet from the manufacturer is available and all the measures stipulated therein have been implemented.If there is a risk of fluid leaking from the hydraulic product and contaminating water or the ground, the hydraulicproduct in question must be placed in a suitable collecting trough. In connection with this, the applicable statutoryregulations must be observed.You must also observe the EU directives for the use of workequipment (Directive 89/391/EC) and the associated individual directives, especially Directive 1999/92/EC for the protectionfrom the danger arising from potentially explosive atmospheresand their implementations in national legislation. The legislation contains minimum requirements with respect to the makingavailable by the employer of work equipment and for the useof work equipment by employees at work, including the regulations for operating equipment requiring supervision and theobligation to produce explosion protection documentation. Thisinvolves, for example, dividing areas endangered by potentiallyexplosive atmospheres into zones and specifying suitable workequipment and procedures for these areas.2.2.1 Noise protectionThe A-weighted equivalent continuous sound power level ofRexroth hydraulic products can be obtained from the relevantOperating Instructions. If no values are documented then it canbe taken that the value is less than 70 dB(A).2.2.2 Special points concerning the installation ofcertain productsA Rexroth hydraulic product is intended above all for installation in machines, systems and power units as a part machineor a component for installation into another machine or systemand is not a complete machine in the sense of the EU directive.In addition to the Machinery Directive, still further directivesmay apply, such as the Pressure Equipment Directive or theExplosion Protection Directive.A wide range of dangers can arise from the combined actionsof the hydraulic product and the machine or system in whichthe hydraulic product is installed. Therefore you must alwaysmake sure that the hydraulic product is also suitable withoutrestriction for the proposed application at the installation location. The interfaces with the overall machine and the operating conditions are also of the greatest importance. We recommend that the results of the hazard analysis (risk assessment)of the overall machine are taken into account in the design ofthe hydraulic product.The functioning of the hydraulic product is also influenced bythe machine or system in which it is installed.For this reason, you must also always observe the OperatingInstructions of the overall system in which your hydraulic product is installed. It is most important for you to also consider thepossible use of the hydraulic product in a potentially explosiveatmosphere (see 94/9/EC).IMPORTANTBosch Rexroth points out that, at the time of their first introduction on to the market, hydraulic products comply with therequirements of all relevant EU directives and/or their implementation into national legislation in Germany. If the scope ofdelivery is intended to be installed in a machine or system, thenthe Machinery Directive applies as appropriate – including thethen currently applicable amendments – in that the scope ofdelivery does not necessarily comply with the requirementsof the Machinery Directive because the scope of delivery isintended for installation in a machine or because the scope ofdelivery is intended for combination with other machines into amachine or a hydraulic system.The bringing into use of the scope of delivery shall therefore not be permitted until the machine or system in which thescope of delivery is to be installed or of which it represents acomponent complies with the requirements of all relevant EUdirectives.Details of further responsibilities can be found in3 Important basic safety instructions and in the OperatingInstructions.

If this occurs, contacta doctor immediately!An overview of the training can be found on the Internet athttp://www.boschrexroth.de/didactic.3.5.2 Malfunctions due to contamination ofpressure fluid3.5General ancillary dangers andprotective measures when operatinghydraulic productsDANGERContamination of the pressure fluid can be caused by:¾ Wear during operation of the machine/system (metallicand non-metallic abrasion)¾ Leaks of the hydraulic product¾ Contaminants introduced during servicing/repairIn the interests of your safety, all safety instructions shall becarefully observed, especially those in the Operating Instructions.¾ The use of dirty (unfiltered) pressure fluid when the pressure fluid is changed.In spite of the high intrinsic safety of Rexroth hydraulic products, the risk of personal injury or damage to the environmentcannot be excluded, even when the equipment is properlyused.Contaminants lead to malfunctions, increased wear and shorterservice life of the hydraulic product. This can have negativeeffects on the safety and reliability of the hydraulic product.New, additional dangers may arise if the hydraulic product isinstalled in another machine or installed with other machinesin a system. This shall apply in particular to mechanical movements generated by the hydraulic product.Information on these additional dangers can be found in theoverall operating manual of the supplier of the overall system inwhich the hydraulic product is installed.Therefore the maintenance tasks specified in the OperatingInstructions shall be carried out at regular intervals and theutmost cleanliness is required during work on the hydraulicproduct.CAUTIONWhen changing the pressure fluid, always use factory-freshpressure fluid and filter it before filling to remove any contaminants in the pressure fluid that it often contains from the packaging container (drum). Flush out lines and hoses before installation.The cleanliness class of a pressure fluid is specified in accordance with ISO 4406. Detailed information can be obtainedfrom the relevant datasheet or the Operating Instructions.1
