Maintenance Schedule for Light Duty
2 Maintenance Work
2.1 Maintenance Schedule
Maintenance operations are to be performed after the corresponding number of operating hours has been
reached or at least once per year, see the maintenance schedule, page 7.
The Maintenance Schedule consists of the basic services M1, M2 and M3 every 400 hours of operation
and additional work M4 dependent on the running hours.
If the relevant operating hours are not reached within one year, the maintenance work is to be performed
annually.
2.2 General information on performing service work
Every maintenance operation is recorded in the “Maintenance Record" section of this book (either accord
ing to the operating hours or the annual intervals).
At each service inspection, the MAN authorised workshop is to confirm the correct performance of the work
according to the maintenance schedule with a stamp and a signature.
Make sure that all entries are legible, complete and have been properly made.
After each service inspection the engine is to be test driven to determine the engine speed which can be
reached at full load (max. ship speed). This value should not be less than the rated speed (see model
plate). This test is valid as proof for the maximum engine power.
Conditions for engine speed test:
S Ship loaded (tanks filled, equipment on board)
S No growth on hull, propeller and shaft system
2.3 Commissioning
As part of the commissioning the “Data on drive system and boat" form, page 1, is to be filled out by the
authorised workshop.
2.4 Daily inspection
A daily inspection has to be performed as part of the board routine:
S Engine oil level / transmission oil level
S Coolant level in expansion tank
S Operation of instruments
S Visual inspection of engine for oil and coolant leaks
S Drain water from fuel filters and fuel pre-filters
