RE 93223-01-B/09.2020, A21VG Series 10, Bosch Rexroth Corporation
NOTICE
Contamination ofhydraulic uid!
The cleanliness ofthe hydraulic uid impacts the service life ofthe axial piston
unit. Contamination ofthe hydraulic uid 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 uids and foreign particles from entering theproduct.
▶ Filter the hydraulic uid when lling the system with asuitable lter 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hydraulic system.
▶ 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 ber-free cleaning cloths for cleaning.
Environmental pollution due toincorrect disposal!
Careless disposal oftheaxial piston unit and its assembled parts,
thehydraulicuid and thepackaging material can cause environmental pollution!
▶ Dispose oftheaxial piston unit, hydraulic uid and packaging inaccordance
with theregulations inyour country.
▶ Dispose ofthehydraulic uid inaccordance with theapplicable
safetydatasheet ofthehydraulic uid.
Danger due tochemical oraggressive environmental conditions!
Product can bedamaged! If theaxial piston unit isexposed tochemical
orcorrosive environmental conditions, such assea water, fertilizer orroad salt,
itcan result incorrosion or, inextreme cases, malfunction. Leaks may lead
toaleakage ofhydraulic uid.
▶ Take appropriate measures toprotect theaxial piston unit from chemical
orcorrosive environmental conditions.
