4.1 Maintenance and Servicing

4.1.1 Maintenance and servicing

Low operating and maintenance costs as well as operational reliability and availability depend on

maintenance and servicing being carried out in compliance with our specifications and instructions. The

overall system, of which the engine is an integral part, must be maintained in such a way as to ensure

trouble-free engine operation. For this purpose, ensure, for instance:

 that sufficient fuel is available;

 that the combustion air is dry and clean.

Of course, your service partner will always be at your disposal to help or assist you if required.

Preventive maintenance instructions

 Special care should be taken to keep the machinery plant in a clean and serviceable condition at all

times to facilitate detection of possible leaks and prevent subsequent damage.

 Protect rubber and synthetic parts from oil and fuel, never treat with organic detergents, only wipe with dry cloth.

 Always replace seals and gaskets.

Maintenance system

The maintenance concept is based on a preventive approach.

Preventive maintenance permits advance operational planning and increases availability. The maintenance

schedule refers to the specified load profile. The time intervals according to which the maintenance operations

are to be performed and the relevant inspection and maintenance tasks are based on operational experience

and are therefore to be considered as approximate values. Particular operating conditions may require the

maintenance schedule to be altered. Remanufactured parts are offered for components to be replaced.

Information on maintenance intervals

The maintenance intervals for oil and coolant are specified in the (

MTU Fluids and Lubricants Specification,

Publication No. A001061/..) Use only fluids and lubricants which are approved by MTU.

The following maintenance operations must be performed on direct responsibility of the user / customer:

Fuel prefilter:

Maintenance depends on fuel quality (purity).

The fuel prefilter must be replaced after 2 years, at the latest. (

Battery:

Maintenance intervals of batteries depend on operating and ambient conditions. The

information of the battery manufacturer is binding.

Out-of-service periods

If the engine is to remain out of service for more than one month, carry out engine preservation in accordance

withthe(
