1. General
It is assumed that the engine room personnel has the necessary knowledge and experience
required for the proper maintenance and servicing of diesel engines. For this reason and in
the interest of clearness we did not go too much into details in the maintenance docu-
ments.
No claims can be raised owing to missing instructions in the maintenance documents, if
damage is caused by improper handling.
All information refers to the date of printing.
2. Explanation of the maintenance system
2.1 Scheduled maintenance
With “Scheduled maintenance” the economic operation of supercharged engine is in the
long run not possible at today's state of art.
The explanations are used to make the user of this engine plant familiar with the existing
maintenance system of MaK and to interest and deepen the understanding of the user for
the problems and importance of the “Scheduled maintenance”.
It is the purpose of the maintenance to replace parts subject to wear and tear or to repair
these parts before they are damaged.
The “Scheduled maintenance” is thereby supported by inspections according to fixed
deadlines. These inspections are decision criteria for the need and extend of maintenance
and servicing.
The following is used as parameter:
• data on wear and tear
• evaluation criterion and
• performance checks
Most of the work to be carried out does not have a fixed deadline since the service life of
individual components is highly influenced by environmental and operating conditions,
fuel qualities and their care.
Therefore the present interval schedule shall not be considered stringent in the long run,
but it is left to the user to modify the maintenance schedule in accordance with own
experiences.
But in any case a sufficient safety margin - even if the mean wearing levels are well-
known - is to be calculated in order to cover the always occurring variations.
It is recommended to consult MaK with regard to extended intervals in order to maintain
the guarantee.
The information given by us gives no rise to legal claims.
