Maintenance Schedule; Putting Out Of Service - Mastervolt WHISPER 3,5 User Manual

EVERY 1000 HOURS:
• 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 re-
placed.
• 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 proce-
dure.
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 stove 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.
