tect yourself, those around you and
the equipment.
Read all informations supplied with

nance of the boat and all equip-
ment has been done in accordance
with the instructions stated in the
relevant Manual. Have all mandato-
ry and necessary safety equipment
handy in the boat and serviceable.
Emergency kit
You can order an emergency kit
from any Nanni authorized dealer.

Safety
precautions
Exhaust gas
Exhaust gases contain carbon
monoxide. This colourless and
odourless gas is extremely har-
mful and could lead to poisoning
which could result in loss of
consciousness or death. The first
symptoms of carbon monoxide
intoxication are as follows:
• Dizziness
• Nausea
• Headache
• Throbbing temples
• Vomiting
• Fatigue and falling asleep
• Tense muscles
If you or anyone else in the vicinity
of the engine experiences any of
these symptoms, leave the area
of operation of the engine and find
fresh air. If the symptoms persist,
consult a doctor and have the en-
gine checked.
Ensure the exhaust circuit correctly
expels the gas produced by the
engine. Regularly check that the
exhaust circuit is free of leaks and
that the exhaust elbow is in good
condition.
Burns
Never touch the hot parts of the
engine! An operational engine gets
very hot: the exhaust system, tur-
bocompressor (if equipped), starter,
oil sump, oil, coolant in the hoses
and pipes are hot and can burn.
Fluids ejected under pressure can
cause serious injury. Release all
the pressure in the circuits before
removing the caps. Never open the
oil circuit and coolant caps when
the engine is operational and/or
hot. Never start or run the engine
when the oil fill and coolant caps
are not screwed on as hot oil or
coolant could spray out.
If you come into contact with any
of these fluids, consult a doctor
immediately. If the engine gets too
hot, switch it off and disconnect it
and wait for it to cool down before
checking for failure.
Fire
Do not smoke near the engine and
keep it away from sources of igni-
tion (flames or sparks) or any other
potential flammable vapour or liquid
sources. Do not run the engine
without the air filter.
Do not run the engine in an area
in which flammable or explosive
materials are stored or where gas
is present. Ensure there are no
flammable liquids in the engine
compartment.
5
Immediately clean up any liquids
spilled and keep the engine com-
partment clean and accessible so
as to minimise the risk of fire. Be
careful as fuel can burn. Damaged
pipes can lead to fire.
Explosion
Explosions caused by fuel vapour
can cause serious injury! Carefully
follow the safety rules when filling
the fuel.
Open and ventilate the storage
area of the engine after filling.
Check that there are no fuel va-
pours or leaks before starting the
fan (if fitted). Switch the fan on for 5
minutes before starting the engine.
All fuel vapours are flammable
and explosive. Be careful when
handling and storing fuel. Store
the fuel in a ventilated area away
from sources of ignition (sparks
or flames) and out of the reach of
children.
Stop the engine before filling with
fuel or lubricant. Do not smoke near
the engine and keep it away from
sources of ignition (flames) when
filling with fuel and/or lubricant.
Wear gloves when investigating
possible leaks.
Do not alter or damage the fuel cir-
cuit. Close the fuel circuit whenever
you work on it. Ensure you always
have an appropriate working fire
extinguisher to hand.
Hazardous Voltage/
Electrical Shock
Electrocution is possible whenever
electricity is present. Hazardous
voltage can cause severe injury
or death. Operate the engine only
when all guards and electrical en-
closures are in place.
Open the main circuit breakers
of all power sources before servi-
cing the equipment. Configure the
installation to electrically ground the
engine, transfer switch, and related
equipment and electrical circuits to
comply with applicable codes and
standards.
Never contact electrical leads or
appliances when standing in water
or on wet ground because these
conditions increase the risk of
electrocution. The voltage at these
terminals can cause death.
Short circuits can cause bodily
injury and/or equipment damage
Remove all jewellery before servi-
cing the equipment.
Hazardous backfeed voltage can
cause severe injury or death.
Connect the engine to the buil-
ding/marina electrical system only
through an approved device. Work
on the electrical circuit should only
be carried out by qualified techni-
cians.
Operations on the shore power
equipment must only be carried out
by electricians authorized to work
with high voltage installations.
6
Special attention must be brought
on boat with metallic hull, especially
concerning the protection of the
persons against electrical shock
and the protection against galvanic
and electrolytic corrosion.
Battery acid
The acid in batteries can cause
serious injury and even death!
When servicing the batteries, wear
protective gloves and goggles. Bat-
teries contain sulphuric acid which
is highly corrosive.
Acid can spurt from batteries when
they are handled. If the acid comes
into contact with the skin, rinse tho-
roughly in fresh water and consult
a doctor.
Risk of battery explo-
sion
A battery explosion can cause
serious injury and even death! En-
sure the battery storage compart-
ment is corrected ventilated.
Do not smoke near the batteries
and keep them away from sources
of ignition (flames or sparks). They
produce hydrogen which could
ignite or explode on contact with an
electrical arc or a flame.
Switch off all electrical appliances
in the vicinity when you are working
on the batteries.
Ventilate correctly storage batteries
compartment. Avoid touching the
battery terminals with metal tools
so that no sparks are created which
could cause an explosion. Remove
the rings, bracelets and necklaces
before handing the batteries.
Rotating parts
Rotating parts can be extremely
dangerous and cause serious injury
and even death!
Do not work on the engine when
it is operational. If work on the
engine when running is absolutely
necessary, do not touch any hot or
rotating parts.
Baggy clothing, hair or objects
could be pulled in and/or caught
and cause serious injury or subs-
tantial property damage.
Do not wear bracelets, necklaces
or rings when working on a engine.
Check that the bolts and screws
are properly tightened and that
the protection mechanisms are in
place. Do not check the tension of
the alternator belt when the engine
is operational.
