7 Periodic maintenance work
7.1 Foreword to maintenance
Maintenance work includes regular visual controls and cleaning operations which are inten-
ded to ensure the trouble-free functioning of the turbocharger.
To allow you to observe the standard service intervals and to maintain a high turbocharger
efficiency, Turbo Systems recommends that the cleaning procedure be carried out during
operation. This allows the thermal load of the engine to be kept low while ensuring max-
imum fuel efficiency.

If the maintenance intervals are incompatible with operation of the engine, contact Turbo
Systems.

Turbo Systems recommends having mechanical cleaning carried out by a Turbo Systems
service station during the service work. Otherwise, only carry out mechanical cleaning if
cleaning during operation is not sufficient to achieve the thermal load and the rating of the
engine.
