The regular maintenance of your generating set is
essential for ensuring optimal reliability and service life.
The following operations and the those described in the
Silverwake warranty booklet will enable you to extend
the service life of your engine and reduce its impact on
the environment.
During the warranty period, it is essential that all work
is carried out by a Nanni Diesel authorised dealer.
However, some regular checks, particularly those made
each time the engine is used, can only be made by the
user.
Some operations are explained to you further on so that
you can work on the engine in an emergency or if there
is no repair centre nearby. However, we recommend you
have your work checked by a Nanni Diesel authorised
dealer.
I
Caution! :
As far as possible, limit work on the engine
when it is under operation and/or when you are sailing.
These instructions only describe a part of the
maintenance operations to be carried out. Find the
complete list on the Silverwake warranty booklet. The
operations listed on the Silverwake must be carried out
by an authorised Nanni Diesel technician.
The instrument panel shows you how long your engine
has run since its commissioning.
Notice:
Some equipments are optional and may not be
part of your generating set.
In order to preserve the mechanical qualities of the
engine and prolong its service life, we recommend you
follow the instructions below:
Use a coolant made of 50% water and 50% of pure
antifreeze. Use clean and distilled water for the mix:
Water that is too hard will produce limescale build-up
and will reduce the cooling system’s effectiveness.
The cooling system allow the engine to operate at a
optimal temperature. The cooling system must be filled
with a coolant that protects the engine against internal
corrosion and from freezing, if the climate requires it.
A faulty operation of the cooling system reduces its
efficiency and therefore the engine’s service life.
Use antifreeze depending on climatic conditions: it will
protect against freezing to a temperature of less than
-25°C. If the engine must be switched off for a long
period in an environment with a high risk of frost, the
coolant must be drained.
Do not engage the starter motor for more than 10
seconds:
The continuous use of the starter for more
than 10 seconds will damage the system.
Choose a diesel fuel meeting standard DIN-EN
590. If using Biodiesel (according to UNI EN14214
specifications) this can be blended up to 5% with
a fuel available in Europe (according to the DIN EN
590 standard:
a lower quality fuel will result in poor
combustion, which may cause starting problems and
heavy smoke emissions.
Draining the fuel tank:
Remove the deposits in the fuel
regularly. The first time after 50 hours of operation and
then every 300 hours.
Use a good-quality lubricant:
Poor-quality lubricating
oil will damage the engine in terms of the wear of the
parts, jamming, etc., or rather reduce its service life.
Use an API-CF mini type oil adapted to the climatic
conditions and temperature (Contact your local dealer
for further informations).
