7.4 Maintenance of general construction

To ensure a long life span for the general construction of the machine, the
machine exterior should be kept clean and should periodically be inspected for
rust, leaks and other defects. Dirt on the machine exterior exposes the frame to
corrosion and can affect the cooling of the machine.

7.4.1 Checks during running of the machine

During the first days of running it is important to keep the machine under close
surveillance in case any changes occur in the vibration or temperature levels or
there are abnormal sounds.
During running, pay special attention to temperature and vibration levels, see
Chapter 7.4.2. Vibration and noise and Chapter 7.4.3. Temperature levels.
