7.4 Installing the axial piston unit

7.4.1 Preparation

1. Check the specifications on the name plate to see you have the correct
axial piston unit.
2. Compare the material number and designation (type code) with the details in the
order confirmation.
If the material number for the axial piston unit does not match the one in the
order confirmation, contact your local contact person for clarification. You can
find their contact information at
www.boschrexroth.com/addresses
3. Before installing, completely drain the axial piston unit to prevent mixing with
the hydraulic fluid used in the machine/system.
Check the permissible direction of rotation of the axial piston unit (on the name
4.
plate) and make sure that this corresponds to the direction of rotation
of the drive motor.
