EVERY 300 HOURS:
•
Check the impeller of the alternator coolant
pump.
•
Replace the oil filter.
•
Replace the fuel filter
Replacement depends or the condition of the
fuel. We recommend replacement every 300
hours. Isolate the fuel supply and change the
element.
EVERY 500 HOURS:
•
Check the air strainer element
•
Replace the impeller of the alternator coolant
pump.
When replacing the impeller the gasket between the pump
case and the cover should be replaced as well. So when
ordering a spare impeller order a gasket as well. Remove
the cover to get access to the impeller. Remove the old
impeller with the help of two screwdrivers. Install the new
impeller and add some grease. Turn the blades in the
direction of rotation of the pump i.e. anti clockwise looking
at the impeller.
EVERY 1000 HOURS:
•
Replace the V-belt.
•
Retighten the cylinder head bolts and adjust the
valve clearance. (Refer to § 5.4.2).
•
Check and clean the radiators
EVERY 2000 HOURS:
•
Replace or clean the air strainer element
•
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.
When the generator set runs less than 100
hours a year the oil should be changed yearly

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.
5
The coolant can stay in the engine
6
Disconnect the battery and store it in a place free of
frost and dry and charge it regularly.
7
Close inlet- and outlet openings with tape.
8
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.
