6 Periodic maintenance work
6.1 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, ABB Turbocharging recommends that the cleaning procedure be carried out dur-
ing 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 ABB
Turbocharging.
2)
ABB Turbocharging recommends having mechanical cleaning carried out by an ABB Tur-
bocharging Service Station during the service work (see also chapter Service work according
to data on the rating plate →36). Otherwise, only carry out mechanical cleaning if cleaning
during operation is not sufficient to achieve the thermal load and the rating of the engine.
