tions and warnings. We urge you

to read it carefully and familiarize

yourself with the engine before

starting.

For your own safety and longer

service life of the engine, follow

the instructions and warnings

contained in this manual and in all

documentation provided with the

boat. Ignoring them could result in

damage to the engine or personal

injury to you or others.

Please ensure that this Manual is

always kept in the boat. It should

always be available to anyone

else using the engine, i.e. anyone

renting, borrowing or buying the

engine from you. Throughout the

document, the following symbols

Content and updates

All the informations and specifica-

tions in this Manual are based on

the technical data applicable at the

time of its publication. Changes and

updates may be made by Nanni

Illustrations are intended as a

general guide, and may vary from

the equipment fitted in the engine in

some details. Some sections of the

Manual do not apply to all engines.

If this is the case, a text indicates

and operating procedures.



Read this chapter carefully as it

concerns your safety. Most acci-

dents are caused by failing to follow

basic safety rules. Be aware of the

possible risks involved in handling

the engine and make sure to take

the necessary precautions to pro-

tect yourself, those around you and

the equipment.

Read all informations supplied with

the boat before starting the engine

for the first time.

Always ensure that the mainte-

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.

The engine emergency kit contains

several components to carry out

simple repair in the event of a fault.

Always have an complete emer-

gency kit onboard and necessary

tools to carry out any repairs.

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.

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.

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.
