Information about replacement intervals
The specified values are only guide values and not guaranteed.
They can vary significantly due, for example, to inadequate servicing,
frequent emergency shutdowns and the use of fuel or lubricating oil of
inferior quality.
A speed measuring system permits continuous monitoring of the tur-
bocharger speed.
CAUTION
Do not use cables as a climbing aid
If you pull the speed measurement cables too hard, contacts can be
pulled out.
