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.

Turbo Systems recommends having mechanical cleaning carried out by a Turbo Systems
service station during the service work (see also chapter Service work according to data on
the rating plate →58). Otherwise, only carry out mechanical cleaning if cleaning during opera-
tion is not sufficient to achieve the thermal load and the rating of the engine.
