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, 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.

Turbocharging.

ABB Turbocharging recommends having mechanical cleaning carried out by an ABB Tur-
bocharging 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.
