4. Service, maintenance and troubleshooting
4.1 Service
1. In general it is provided that service of the EA is performed by a qualified worker in accordance with
requirement given in Chapter 1!
2. After putting the EA into operation it is needed to verify whether during manipulation any scratch on
surface occurred, it is to be removed to prevent actuator against corrosion!
The EA ST/STR requires just negligible service. Proper putting into operation is a recondition of
reliable operation.
The service of the EA leads from the operation conditions and usually resides in information
processing for further arranging of required functions.
The stuff has to perform prescribed maintenance to prevent the EA during operation against
impacts of environment, which exceed the frame of allowed influences.
