machinery is exclusively intended to form an incomplete or a complete machine
together with other components or partly completed machineries. The DOb drive
unit may 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 machine directive.
Intended use includes having read and understood the complete documentation,
especially the chapter 2: Safety instructions.
The product is intended for the following use:
• Create hydraulic ow in a open loop hydraulic system.
Standard drive units are not allowed to be used outside an ambient temperature of
0 °C to 40 °C (32 °F to 104 °F) or in areas with potentially explosive atmospheres.
2.3 Improper use
Any use other than that described as intended use shall be considered as improper
and is therefore impermissible.
Bosch Rexroth shall accept no liability whatsoever for damage resulting from
improper use. The user shall bear all risks arising from improper use.
Similarly, the following foreseeable faulty usages are also considered to be improper:
• Using outside the operating parameters approved in the product-specic data
sheet or in the order conrmation (unless customer-specic approval has been
granted)
• Use of uids outside of the standards as specied in RE15414 Hydraulic fluid quick
reference.
• Modication of factory settings by non-authorized persons
• Use of add/on parts (e.g. mountable lter, control unit, valves) that are not
specied by Bosch Rexroth has to be approved by contact at Bosch Rexroth.
8/80 Safety instructions
Bosch Rexroth AB, Installation and maintenance manual, Hägglunds DOb, RE 15327-WA/05.2017
• Extension or conversion is not permissible and has to be approved by contact at
Bosch Rexroth.
• Using the Drive unit in explosive environments unless the component or machine/
system has been certied as compliant with the ATEX directive.
• Using the Drive unit in an aggressive atmosphere without necessary additional
measures.
2.4 Personnel qualications
The activities described in this documentation require basic mechanical, electrical
and hydraulic knowledge, as well as knowledge of the associated technical terms.
For transporting and handling the product, additional knowledge is necessary with
regard to working with a lifting device and the corresponding attachment equipment.

appropriate qualied personnel or an instructed person under the direction and
supervision of qualied personnel.
Qualied personnel are those who can recognize possible hazards and institute
the appropriate safety measures due to their professional training, knowledge, and
experience, as well as their understanding of the relevant regulations pertaining
to the work to be done. Qualied personnel must observe the rules relevant to the
subject area and have the necessary hydraulic, electric and automation knowledge.
Hydraulic knowledge means, for instance:
• reading and fully understanding hydraulic diagram,
• fully understanding in particular the interrelationships regarding safety devices and
having knowledge on the function and assembly of hydraulic components.
Electric knowledge means, for instance:
• Reading and fully understanding of electrical diagrams
• Certication for work with electrical equipment
