3.6.7.1 Service life
The rotors and accessories have a limited service life.
WARNING
• Perform regular checks (at least once per month) for safety reasons!
• Pay special attention to changes, such as corrosion, cracks, material
abrasion, etc.
• After 10 years, they must be inspected by the manufacturer.
• After 50,000 cycles, the rotor must be scrapped for reasons of safety.
• If other data concerning the service life are engraved on the rotor or
bucket, these data shall apply accordingly. For example, a bucket with
the engraving “max. cycles = 10,000” has a service life of 10,000
cycles, and a rotor with the engraving “Exp. date 02/20” must be
scrapped in February 2020 at the latest (see figure).

life (see chapter 11.3 - "Table of the service life of rotors and
accessories")!
