accessories from Bosch Rexroth.

8.1 Initial commissioning

During all work for commissioning the axial piston unit, observe the general
safety instructions and intended use detailed in chapter 2 "Safety instructions"
on page 8.
▶ Connect the gauge for the operating pressure, case pressure and suction
pressure to the specified measuring points on the axial piston unit or in the
hydraulic system, to check the technical data at first operation.
▶ During the commissioning process, monitor the temperature of the hydraulic
fluid in the reservoir to ensure that it lies within the permissible viscosity limits.

8.1.1 Filling the axial piston unit

Professional filling and air bleeding is necessary to prevent damage to the axial
piston unit and to maintain correct function.
Usually, the cleanliness level of commercial hydraulic fluids is insufficient for
our components. These hydraulic fluids must be filtered during filling using
an appropriate filter system to minimize solid particle contamination and water
in the system.
Use only a hydraulic fluid that corresponds to the following requirements:
You can find details on the minimum requirements for hydraulic fluids in
Bosch Rexroth data sheets 90220, 90221, 90222, and 90223. The titles
