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92704 and in the order
confirmation. Information about approved hydraulic fluids can be found in
datasheet92704.
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and 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

Safety instructions 9/60
RE 92704-01-B/2020-01-21, A10VOH Series60, Bosch Rexroth AG
• 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
equalization. Units with electrical components (e.g.sensors) generally cannot
come into contact with water. Axial piston units may only be used on a case-to-
case basis for this application.
• The maximum permissible case pressure specified in the datasheetmust not be
exceeded.
• Application 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
• Knowledge regarding the function and interaction of hydraulic components
BoschRexroth offers you measures supporting training in specific areas. You

Bosch Rexroth AG, A10VOH Series60, RE 92704-01-B/2020-01-21
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 areas 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/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 appropriately implemented.
• Depending on the type of control used, electromagnetic effects can be produced
when using solenoids. Applying a direct voltage signal (DC) to solenoids does not
create electromagnetic interference (EMI) nor is the solenoid affected 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.
