8 Commissioning

Danger while working in the danger zone of a machine/system!
Danger to life, risk of injury or serious injury!
▶ Pay attention to and eliminate potential danger sources before operating the
axial piston unit.
▶ Make sure no one is in the danger zone of the machine/system.
▶ The emergency stop button for the machine/system should be within the
operator's reach.
▶ Always follow the instructions of the machine/system manufacturer during
commissioning.
Commissioning an improperly installed product!
Risk of injury and property damage!
▶ Make sure all electrical and hydraulic ports are connected or plugged.
▶ Commission only a fully installed, fully functioning product with original
accessories from Bosch Rexroth.

8.1 Initial commissioning

During all commissioning work on the axial piston unit, observe the general safety
instructions and intended use detailed in chapter 2 "Safety instructions" on
page 9.
▶ Connect the pressure gage for the working 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 commissioning, monitor the temperature of the hydraulic fluid in the
reservoir to ensure that it lies within 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 proper function.
Usually, the cleanliness level of commercial hydraulic fluids is insufficient for our
components. These hydraulic fluids must be filtered using an appropriate filter
system to minimize solid particle contamination and water in the system.
Use only a hydraulic fluid that conforms to the following requirements:
You can find details of the minimum requirements on hydraulic fluids in Bosch Rexroth
data sheets 90220, 90221 and 90223. The titles of the data sheets can be found in
Table 1 "Required and supplementary documentation" on page 5.
You can find details of permissible and optimal viscosity in data sheet 92701 and 92711.
