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 correspond to the one
in the order confirmation, contact your local contact person for clarification,
you can find the address under

3.
Before installing, completely drain the axial piston unit to prevent mixing with the
hydraulic fluid used in the machine/system.
4. Check the direction of rotation of the axial piston unit (on the name plate) and
make sure that this corresponds to the direction of rotation of the drive motor.
