described in this manual.
10�1 Cleaning and care
NOTICE
Damage to the hydraulic system and the seals!
The jet of a high-pressure cleaner can damage the seals and electrical system of
the control block!
▶ Do not point high-pressure cleaners at sensitive components like electrical
connections and components.
For cleaning and care of the control block, observe the following:
▶ Check whether all the seals and fittings on the plug-in connections are securely
seated to ensure that no moisture can penetrate into the control block during
cleaning.
▶ Use only water and, if necessary, a mild cleaning agent to clean the control
block. Never use solvents or aggressive cleaning agents.
▶ Remove major external contamination and keep clean sensitive and important
components, such as solenoids, valves, indicators and sensors.
10�2 Inspection
In order to enable long and reliable operation of the control block, Bosch Rexroth
recommends testing the hydraulic system and the control block on a regular basis,
and documenting and archiving the following operating conditions:
Table 7: Inspection schedule
Work to be performed on the control block
Interval
Check operating temperature
Weekly
Hydraulic fluid analysis: Viscosity, aging and contamination
Annually or every 2000
operating hours
Inspect the control block for external leakage (visual inspection).
Daily
Inspect the control block for unusual noise development.
Daily
Check mounting elements for tight seating.
All mounting elements must be checked when the control block
is depressurized, deenergized and has cooled down.
