The regular maintenance of your engine 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 owner.
Certain 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. We recommend you have your
work checked by a Nanni Diesel authorised specialist.
I
Attention! :
As far as possible, limit work on the engine
when it is running 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.
Remark:
Certain equipment is optional and may not be part
of your engine.
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% antifreeze.
Use tap water for the mix:
Water that is too hard will
produce limescale build-up and will reduce the cooling
system’s effectiveness. This could lead to a piston jamming.
If you do not use antifreeze and the outdoor temperature
is below zero degrees Celsius, make sure to empty the
cooling water after every use.
The closed cooling circuit must be protected against
corrosion. If this circuit malfunctions, this could reduce its
efficiency and the engine’s service life.
Do not run the starter for more than 15 seconds:
The
continuous use of the starter for more than 15 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.
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.
The recommended lubricant must have the following
properties :
Degree:
SAE 10W - 40
Minimum specifications
ACEA A3, B3 or API SL, CF
