EVERY 1000 HOURS:
•
Replace the fuel filter
Replacement depends on the condition of the
fuel. We recommend replacement every 1000
hours. Isolate the fuel supply and change the
element.
•
Clean the oil strainer.
EVERY 2000 HOURS:
•
Check lubricating oil pressure
•
Clean and check or replace fuel injector nozzles
and check injection pressure.
•
Check the air filter element:
The air is taken in via the cover on the alternator.
Below this cover is a spongy material which filters
the air and holds some electrical components
which are cooled by the inlet air. This filter does
not require regular maintenance. Only in very
dusty circumstances this filter should be cleaned.
The spongy material can be washed in solvent or
replaced.
•
Check the cooling system:
The engine oil is indirectly cooled by raw water
via an oil cooler/ heat exchanger. The alternator
is cooled by seawater which is pumped by the
PTO driven impeller pump through the cooler
elements in the generator housing. All parts of
the cooling system are of corrosion free and
seawater resistant materials such as brass and
gunmetal. In case of gathering of dirt in the
system it could be cleaned by compressed air.
When overhauling the engine one could clean the
parts thoroughly or replace.
When the generator set runs less than 100
hours a year the oil should be changed yearly

4.3.2 Putting out of service
When not using the generating set for a longer period it is
recommended to execute an engine preservation
procedure.
1 Clean the engine.
2 Loosen the fuel suction pipe and fuel return and put
them in a can with preservation diesel fuel. Start the
engine and run the engine warm.
3 Drain the hot engine oil and refill with preservation oil.
4 Stop the engine and loosen the inlet of the raw water
pump. Drain the water from the water lock. Lift the
valves by the decompression handle to avoid the
engine from starting and crank the engine having the
raw water inlet sucking anti freeze from a can until the
pump, heat exchanger and manifold are full.
5 Disconnect the battery and store it in a place free of
frost and dry and charge it regularly.
6 Close inlet- and outlet openings with tape.
7 Protect the generating set against the influences of
bad weather conditions.
This method of preservation will be sufficient for 6 months.
Repeat steps 2, 3, and 4, every 6 months. Change oil
before using the engine again.
