2 Safety instructions

2.1 About this chapter

The axial piston unit has been manufactured togenerally accepted engineering

standards. There isstill, however, arisk ofpersonal injury orproperty damage ifthis

chapter and the safety instructions inthis documentation are not observed.

▶ Read this documentation completely and thoroughly before working with the axial

piston unit.

▶ Keep this documentationinalocation where itisaccessible toall users atall

times.

▶ Always include the required documentation when you pass the axial piston unit

onto third parties.

2.2 Intended use

Axial piston units are hydraulic components, meaning that intheir application

area they are classiﬁed neither ascomplete nor aspartly completed machinery

asdeﬁned inthe ECMachineryDirective2006/42/EC. The component isexclusively

intended toform partly completed machinery orcomplete machinery together with

other components. The component should only becommissioned after ithas been

installed inthe machine/system for which itisintended and the safety oftheentire

system 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open

circuit.

▶ Observe the technical data, the application and operating conditions and

the performance limits asspeciﬁed inthe datasheet 92801 and inthe order

conﬁrmation. Information about approved hydraulic ﬂuids can befound

indatasheet 92801.

The axial piston unit isonly intended for commercial use and not for private use.

Intended use includes having fully read and understood this documentation,

especially chapter2 "Safety instructions" onpage 8.

2.3 Improper use

Any 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

issolely responsible for any risks arising from improper use.

The following foreseeable forms offaulty usage are also considered improper

(thislist isnot exhaustive):

• Use outside the operating parameters approved inthe data sheet orinthe order

conﬁrmation (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.control unit, valves) not incombination with the

speciﬁedRexroth components

• Use oftheaxial piston unit with assembled parts under water atadepth ofmore

than 10meters without the necessary additional measures, e.g.pressure

Safety instructions 9/60

RE 92801-01-B/11.2018, A15VSO/A15VLO Series 11, BoschRexrothAG

equalization. Units with electrical components (e.g.sensors) generally cannot

come into contact with water.

• Use oftheaxial piston unit under acontinuous pressure diﬀerential between

housing and ambient pressure greater than 2bar, with the ambient pressure always

lower than the case pressure. Momentary (t<0.1s) pressure peaks ofup to10bar

are allowed. Beyond this, the maximum permissible case pressure speciﬁed inthe

datasheet should not beexceeded.

• Use oftheaxial piston unit inexplosive environments unless the

component ormachine/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spacecraft

2.4 Personnel qualiﬁcations

The activities described inthis documentation require abasic understanding

ofmechanics, electricity and hydraulics, aswell asfamiliarity with associated

technical terms. For transporting and handling the product, knowledge regarding

the use oflifting devices and lifting accessories isrequired. Inorder toensure safe

use, these activities should only beperformed byskilled personnel oraninstructed

person under 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 relevant

tothe work tobedone that are necessary torecognize possible dangers and take

the appropriate safety measures. Skilled personnel must follow the rules relevant

totheir ﬁeld and have the necessary hydraulic expert knowledge.

Hydraulic expert knowledge includes:

• Being able toread and fully understand hydraulic circuit diagrams

• In particular, fully understanding the relationships with regard tosafety devices

• comprising ofknowledge regarding the function and layout ofhydraulic

components.

BoschRexroth oﬀers you measures supporting training inspeciﬁc areas. You can

10/60 Safety instructions

Bosch Rexroth AG, A15VSO/A15VLO Series 11, RE 92801-01-B/11.2018

2.5 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 inﬂuence

ofalcohol, drugs ormedication that may aﬀect your reaction time.

• Only use genuine Rexroth accessories and spare parts toensure there isno hazard

to persons from unsuitable spare parts.

• Observe the technical data and ambient conditions speciﬁed inthe product

documentation.

• Ifunsuitable products are installed orused inapplications that are ofrelevance

tosafety, unexpected operating conditions may occur inthe application, which

could result inpersonal injury orproperty damage. For this reason, only use

the product insafety-relevant applications ifthis use isexpressly indicated and

approved inthe product documentation, e.g.in explosion protection applications

orinsafety-related 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 complies

with the country-speciﬁc provisions, safety regulations and standards for the

application.

• Use tools appropriate for the work being performed and wear appropriate

protective clothing toprevent punctures and cuts (e.g.when removing protective

covers, disassembly).

• There isarisk ofentanglement when operating the axial piston unit with abare

shaft end. Check whether ornot your machine requires additional safety measures

for your application. If necessary, make sure these are properly implemented.

• Depending onthe type ofcontrol used, electromagnetic eﬀects can beproduced

when using solenoids. The energization ofelectromagnets with direct current (DC)

does not produce any electromagnetic interference (EMI), nor istheelectromagnet

inﬂuenced byEMI. Potential electromagnetic interference (EMI) exists

ifthesolenoid isenergized with amodulated direct current (e.g.PWMsignal).

The machine manufacturer should conduct appropriate tests and take appropriate

measures toensure that other components oroperators (e.g.with apacemaker)

are not aﬀected bythis potentiality.
