6 Periodic maintenance work
6.1 Foreword to maintenance
Maintenance work includes regular visual controls and cleaning operations which are intended
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 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 maximum
fuel efficiency.

If the maintenance intervals are incompatible with operation of the engine, contact ABB
Turbo Systems.
2)
ABB Turbo Systems recommends having mechanical cleaning carried out by an ABB
Turbocharging 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.
