Safety instructions
Bosch Rexroth AG, A4VG Series 35, RE 92035-01-B/2019-11-25
• 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
• 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 under a continuous pressure differential between
housing and ambient pressure greater than 2 bar, with the ambient pressure
always lower than the case pressure. Momentary (t < 0.1 s) pressure peaks of
up to 10 bar are allowed, but no more than 1000 pressure peaks over the entire
service life. Beyond this, the maximum permissible case pressure specified in the
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
