14/56 General instructions on damage to equipment and the product
Bosch Rexroth AG, A22VG Series 40, RE 93221-01-B/07.2013
NOTE
Mixing of 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 mixing of hydraulic fluids of different manufacturers or different types of the
same manufacturer is not permissible in general.
Contamination of the hydraulic fluid!
The cleanliness of the hydraulic fluid has a considerable impact on the cleanliness
and service life of the hydraulic system. Contamination of the hydraulic fluid could
cause premature wear and malfunctions!
▶ Make sure that the working environment at the installation site is fully free of
dust and foreign substances in order to prevent contaminants, such as welding
beads or metal cuttings, from getting into the hydraulic lines and causing
product wear or malfunctions. The axial piston unit must be installed in a clean
condition.
▶ Use only clean ports, hydraulic lines and attachments (e.g. measuring devices).
▶ No contaminants may enter the ports when they are plugged.
▶ Before commissioning, make sure that all hydraulic connections are tight and
that all of the connection seals and plugs are installed correctly to ensure that
they are leakproof and fluids and contaminants are prevented from penetrating
the product.
▶ Use a suitable filter system to filter hydraulic fluid during filling to minimize solid
impurities and water in the hydraulic system.
Improper cleaning!
Product can be damaged!
▶ Plug all openings with the appropriate protection equipment in order to prevent
detergents from entering the hydraulic system.
▶ Never use solvents or aggressive detergents. Use only water and, if necessary, a
mild detergent to clean the axial piston unit.
▶ Do not point the high-pressure cleaner at sensitive components, e.g. shaft seal,
electrical connections and components.
▶ Use lint-free cloths for cleaning.
Environmental pollution due to incorrect disposal!
Careless disposal of the axial piston unit and its fittings, the hydraulic fluid and the
packaging material could lead to pollution of the environment!
▶ Dispose of the axial piston unit, hydraulic fluid and packaging in accordance
with the national regulations in your country.
▶ Dispose of the hydraulic fluid in accordance with the applicable safety data
sheet for the hydraulic fluid.
