Before starting
I
Attention! :
Before starting, ensure that the seawater
intake is open as the seawater pump rotor can be dam-
aged if run dry for just a few seconds.
Never use a starting aerosol or any other equivalent prod-
uct. These products are highly flammable.
Before turning the starter key and before the engine is
used each time:
•
Open the hold space panel(s) to fully ventilate the hold
space if it is not equipped with a fan. Otherwise run the
fan in the hold space for 5 minutes.
•
Check the fuel level .
•
Check that the throttle is in the correct neutral position.
•
Open the fuel supply valve and prime the system if
necessary
•
Open the seawater intake valve (if fitted)
•
Check there are no fuel, oil or coolant leaks
•
Check the engine oil level and fill with the recommend-
ed oil if necessary. See the “Maintenance” section for
more information.
•
Check the coolant level and fill with the recommended
coolant if necessary. See the “Maintenance” section
for more information.
I
Attention! :
Ensure you have refitted the protection ele-
ments before starting the engine.
•
Close the battery switch (ON position)
Remark :
If your engine has not been used for several
months of if the fuel circuit has been drained, use the prim-
ing pump situated above the fuel filter. This fills the fuel
circuit if it has drained out or after a circuit component has
been replaced.
I
Danger! :
The propeller can cause serious injury when
it is moving, ensure that no-one is near the propeller before
starting the engine and never sail near swimmers.
Starting the engine
Remark :
When starting the engine for the first time, let it
run at idle for several minutes.
If the engine is not used regularly, turn the ignition and let
the engine run at idle until it reaches operating tempera-
ture. Do this at least one time per month when not in use.
Carry out the following operations to start your engine in
complete safety:
1.
Put the throttle in the neutral position
2.
Put the key into the ON/STOP starting/switch
3.
Turn the key a quarter-turn to the right. All of the in-
dicators will light and an audible signal will sound. This
stage allows you to check that these elements are work-
ing properly. After a few seconds, only the oil and battery
charge indicators will remain lit.
4.
Depress the START button to the midpoint to begin
heating and keep it depressed for 5 to 20 seconds de-
pending on the ambient temperature. Depress the button
fully to start the engine.
Button panel
For button panels (with no starter key):
1.
Press the ON/STOP button. All of the indicators will
light and an audible signal will sound. This stage allows
you to check that these elements are working properly.
After a few moments, only the oil and battery charge indi-
cators will remain lit.
2.
Depress the START button to the midpoint to begin
heating and keep it depressed for 5 to 20 seconds de-
pending on the ambient temperature. Depress the button
fully to start the engine.
I
Attention! :
Never press the START button when the
engine is running.
Remark :
Consult your authorised Nanni Diesel dealer
about the precautions to take when using the engine in a
cold environment.
I
Attention! :
If the engine does not start on the first at-
tempt, repeat the manoeuvre, waiting 5 to 15 seconds be-
tween each attempt, with the engine switched off. Never
force it as there is a risk of water backflow into the engine
via the exhaust system.
Let the engine warm up at idle few minutes before reaching
your cruising speed.
