All parts of a construction machine are exposed to corrosion, especially when the machine is taken out of service. Corrosion can be compared to wear. However, the effects of corrosion can greatly exceed that of mechanical wear and shorten the service life of the affected parts significantly. For that reason, for longer shut down, the machines and its components must be preserved according to certain guidelines.

In general, these guidelines are tiered according to the following times: – Taking the machine out of service – for an unknown duration – Shut down of the machine
• Shut down for up to 2 months
• Shut down for up to 12 months
• Shut down for longer than 12 months
– Return to operation

The required measures are graduated depending on the different time frames. The conservation measures cannot be strictly standardized and they must be shorted or lengthened depending on the assessment of necessity (such as environmental influences).
