10�3 Maintenance
The axial piston unit is low-maintenance when used as intended.
The service life of the axial piston unit is heavily dependent on the quality of the
hydraulic fluid. This is why we recommend changing the hydraulic fluid at least once
per year or every 2000 operating hours (whichever occurs first), or having it analyzed
by the hydraulic fluid manufacturer or alaboratory to determine its suitability for
further use.
The service life of the axial piston unit is limited to the service life of the bearings
used if the permissible operating parameters are observed. You can ask your local
contact person about service life based on load cycle. You can find their contact
information at

Based on these parameters, amaintenance interval should be determined by the
system manufacturer for the replacement of the bearings and included in the
maintenance schedule of the hydraulic system.
