Safety instructions
Bosch Rexroth AG, RE 90300-B/2021-01-19
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):
• Using outside the operating parameters approved in the product-specific
data sheet or in the order confirmation (unless customer-specific approval has
been granted)
• Use for non-approved fluids, e.g. water or polyurethane components
(exception: plastic feed pump)
• Changes to factory settings by unauthorized persons.
• Use of assembled parts (e.g. attachment filter, control unit, valves) other than
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
equalization. Units with electrical components (e.g. sensors) generally cannot
come into contact with water.
• Use of the axial piston unit when ambient pressure is greater than internal pressure
(case pressure). Beyond this, the maximum permissible case pressure specified in
the product-specific data sheet should 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
