Maintenance and repair | Control blocks for mobile applications
10�3 Maintenance
The control block is low maintenance when used as intended.
The service life of the control block 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 a laboratory to determine its
suitability for further use.
Observe the following general rules:
From a hydraulic fluid temperature of > 70 °C the aging speed doubles with
every 10 °C of temperature increase.
The maximum permissible degree of contamination of the hydraulic fluid can be
seen in the data sheet in Chapter "Technical data".
Please also observe the parameters on hydraulic fluid in the machine's
instruction manual.
