14/72 Safety instructions
Bosch Rexroth AG, axial piston variable pump A4VSO, RE 92050-01-X-B1/2019.08.23
Danger from excessive pressure!
Danger to life, risk of injury or property damage!
Improperly changing the factory pressure settings can result in a pressure increase
beyond the maximum permissible pressure.
Operating the unit above the maximum permissible pressure can cause
components to burst and hydraulic fluid to escape under high pressure.
▶ Changes to the factory settings may only be made by Bosch Rexroth specialists.
▶ If the axial piston unit is equipped with a pressure cut-off and/or pressure
controller, this is not an adequate safeguard against pressure overload.
▶ Set the external pressure relief valve so the maximum permissible pressure
cannot be exceeded; see data sheet (Part II).
▶ Set the opening pressure of the high pressure relief valve to a value of at least
30 bar above the value set at the pressure controller.
Danger due to suspended loads!
Danger to life, risk of injury or property damage!
Improper transportation may cause the axial piston unit to fall down and lead
to injury, e.g. crushing or fracture, or damage to the product.
▶ Make sure that the fork lift truck or lifting device has adequate lifting capacity.
▶ Never step or grip under suspended loads.
▶ Ensure a stable transport position.
▶ Use your personal protective equipment (e.g. safety goggles, safety gloves,
suitable working clothes, safety shoes).
▶ Use suitable lifting devices for transport.
▶ Observe the prescribed position of the lifting strap.
▶ Observe the national laws and specifications of occupational safety and health
and transport.
System/machine under pressure!
Danger to life or risk of injury, serious injuries when working on machines/systems
that are not shut down! Property damage!
▶ Secure the entire system against being re-energized.
▶ Make sure that the machine/system is depressurized. For this purpose, observe
the parameters indicated by the machine/system manufacturer.
▶ Do not disconnect any line connections, ports and components as long as the
machine/system is under pressure.
▶ Switch off all power-transmitting components and connections
(electric, pneumatic, hydraulic, mechanical) in line with the manufacturer's
specifications and secure them against being turned back on.
