Operating limits and replacement intervals
The recommended replacement intervals and the corresponding operating limits in
chapter 3
are jointly defined
with the enginebuilder. This information is specific to the product.
Non-observance of the recommended replacement intervals and the operating limits increases the risk of unpre-
dictable component failures.
