2.2 Intended use
The Hägglunds motor is a radial piston hydraulic motor.
The motor fullls the requirements in accordance with ATEX Directive 2014/34/EU.
In the application the Hägglunds motor is classied as a component in the sense of
the EU machine directive 2006/42/EC. A partly completed machinery is exclusively
intended to form an incomplete or a complete machine together with other
components or partly completed machineries. The motor 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:
• Radial piston motor in open or closed circuit: The radial piston motor is only
approved to be used in motor mode or pump mode for hydrostatic drives.
Observe the technical data, application and operating conditions and performance
limits as specied in the product-specic data sheet and in the order conrmation.
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-specic data
sheet or in the order conrmation (unless customer-specic approval has been
granted)
•Use of uids outside of the standards as specied in Data sheet RE 15414 Hydraulic
uid quick reference.
• Modication of factory settings by non-authorized persons

specied by Bosch Rexroth has to be approved by contact at Bosch Rexroth.
• Extension or conversion is not permissible and has to be approved by contact at
Bosch Rexroth.
• Using the Radial piston motor under water without necessary additional measures.
• Using the Radial piston motor when the exterior pressure is greater than the
interior pressure (case pressure).
• Using the Radial piston motor in an aggressive atmosphere without necessary
additional measures.
2.4 Personnelqualications
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.
In order to ensure safe use, these activities may therefore only be carried out by
appropriate qualied personnel or an instructed person under the direction and
supervision of qualied personnel.
Qualied 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. Qualied personnel must observe the rules relevant to the
subject area and have the necessary hydraulic 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.
Bosch Rexroth oers training support for special elds. For more information about
training, please contact your Bosch Rexroth representative.

2.6 Product-specicsafetyinstructions
DANGER
Danger from excessively high pressure!
Danger to life or risk of injury, damage to equipment!
Operating the motor above the permissible maximum pressure can cause
components to burst and hydraulic uid to escape under high pressure.
▶Operate the motor only within permissible maximum pressure.
Danger from suspended loads!
Danger to life or risk of injury, damage to equipment!
Improper transportation may cause the Hägglunds motors to fall down lead to
injuries e.g. crushing or broken bones or damage to the product.
