▶
Make sure no one is in the danger zone of the machine/system.
▶
The emergency stop button for the machine/system must be within the
operator’s reach.
▶

CAUTIOn
Commissioning an improperly installed product.
Risk of injury and property damage.
▶
Make sure that all electrical and hydraulic ports are connected or plugged.
▶
Only commission a completely installed, fully functioning product with original
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, and specifically project planning and commissioning instructions 90363.
▶
Connect the gauge for the working pressure and case 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.
The axial piston unit should be filled with a filling unit (10 µm filter grade). The
axial piston unit must not be operated while it is being filled by the filling unit.
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 90222. 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 91706.
