Safety instructions 9/68
RE 92105-01-B/06.2017, A4CSG, Series 3x,
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 (for example, sensors) generally
cannot come into contact with water.
• Use of the axial piston unit under a continuous pressure differential between case
to ambient pressure greater than 2 bar, whereby the ambient pressure must always
be lower than the case pressure. Momentary (t < 0.1 s) pressure peaks of up to
10 bar are permitted. Beyond this, the maximum case pressure specified on the
data sheet cannot 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/EC
• 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 basic knowledge of
mechanics, electrics, hydraulics and ATEX, as well as knowledge of the associated
technical terms. For transporting and handling the product, additional knowledge
is necessary with regard to working with lifting devices and their slings. In order to
