10 Maintenance and repair
10�1 Cleaning and care
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/control block segment!
▶ Do not point high-pressure cleaners at sensitive components like electrical
connections and components.
For cleaning and care of the control block/control block segment, observe the
following:
▶ Check whether all the seals and fittings on the plug-in connections are
securely connected to ensure that no moisture can penetrate into the
control block/control block segment during cleaning.
▶ Use only water and, if necessary, a mild cleaning agent to clean the
control block/control block segment. 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 and maintenance
During inspection and maintenance, the following points have to be checked:
• Compliance with operating conditions
• Compliance of requirements for hydraulic fluids according to technical data sheet
• Manifold mounting, ports and leak-tightness
The interval depends on the machine and its application condition.
