General instructions on property damage and product damage
Bosch Rexroth AG, RE 90300-B/2021-01-19
NOTICE
Mixing hydraulic fluids!
Product can be damaged!
▶ Before installation, remove all fluids from the axial piston unit to prevent mixing
with the hydraulic fluid used in the machine/system.
▶ Any mixture of hydraulic fluids of different manufacturers and/or different types
of the same manufacturer is generally not permissible.
Contamination of hydraulic fluid!
The cleanliness of the hydraulic fluid impacts the service life of the axial piston unit.
Contamination of the hydraulic fluid may lead to premature wear and malfunctions!
▶ Always ensure a work environment in the assembly location that is free from dust
and foreign particles to prevent foreign particles, e.g. welding beads or metal
cuttings, from entering the hydraulic lines and lead to wear and malfunctions in
the product. The axial piston unit should be clean when installed.
▶ Only use clean ports, hydraulic lines and assembled parts (e.g. measuring
devices).
▶ When plugging the ports, no contamination may ingress.
▶ Before commissioning, ensure that all hydraulic connections are tight and
that all seals and plugs of the plug-in connection are correctly installed and
undamaged to prevent fluids and foreign particles from entering the product.
▶ Filter the hydraulic fluid when filling the system with a suitable filter system to
minimize the solid particle contamination and water in the hydraulic system and
to achieve the required cleanliness level.
Improper cleaning!
Product can be damaged!
▶ Plug all openings with appropriate protective covers in order to prevent cleaning
agents from entering the axial piston unit.
▶ Never use solvents or aggressive cleaning agents. Use only water and,
if necessary, a mild cleaning agent to clean the axial piston unit.
▶ Do not point a high-pressure cleaner at sensitive components, e.g. shaft seal,
electrical connections and components.
▶ Use fibre-free cleaning cloths for cleaning.
Environmental pollution due to improper disposal!
Careless disposal of the axial piston unit and its assembled parts, the hydraulic
fluid and the packaging material can cause environmental pollution!
▶ Dispose of the axial piston unit, hydraulic fluid and packaging in accordance
with the regulations in your country.
▶ Dispose of the hydraulic fluid in accordance with the applicable safety
data sheet for the hydraulic fluid.
