SAFETY PRECAUTIONS
HOT EXHAUST PRECAUTIONS
Servicing machine or attachments with
engine running can result in serious
personal injury. Avoid exposure and skin
contact with hot exhaust gases and
components.
Exhaust parts and streams become very hot during
operation. Exhaust gases and components reach
temperatures hot enough to burn people, ignite, or melt
common materials.
WORK IN VENTILATED AREA
Engine exhaust fumes can cause sickness
or death. If it is necessary to run an engine
in an enclosed area, remove the exhaust
fumes from the area with an exhaust pipe
extension.
UNWANTED ENGINE START
Avoid possible injury or death from engine
runaway. Do not start engine by shorting
across the starter motor solenoid
terminals posts. Engine will start if normal
circuitry is bypassed. Start engine from
operator’s seat.
SAFE MAINTENANCE PRACTICE
Understand service procedures before
doing work. Keep work area clean and dry.
Never lubricate, service, or adjust engine
while it is running. Keep hands, feet, hair
and clothing away from moving parts.
Fix damage immediately. Replace worn or broken parts.
Remove any build up of grease, oil, or debris. On selfpropelled equipment, disconnect battery ground (-)
before making adjustments on electrical systems or
welding.
If you do not have an exhaust pipe extension, open the
doors and get outside air into the area.
WASTE DISPOSAL
Improperly disposing of waste can threaten the environment and ecology. Potentially harmful waste used in engines include such items as oil, fuel, coolant, fluids
lters and batteries.
Use leakproof containers when draining fluids ; Do not
pour waste into the sea, ground, down a drain, or into
any other water source.
Contact your local environmental or recycling center, or
your dealer for information on the proper way to recycle
or dispose of waste.
WORK IN CLEAN AREA
Clean work area and machine before
starting a job. Make sure you have all
necessary tools to do your job. Have the
right parts on hand. Read all instructions
thoroughly ; do not attempt shortcuts.
PROTECTIVE CLOTHING
Wear close tting clothing and safety equipment
appropriate to the job. Operating equipment safely
requires the full attention of the operator. Do not wear
radio or music headphones while operating the engine.
12
S02 SAFETY
SERVICE ENGINES SAFELY
Tie long hair behind your head. Do not
wear a necktie, scarf, loose clothing, or
necklace when you work near moving
parts. If these items were to get caught,
severe injury could result. Remove rings
and other jewelry to prevent electrical
shorts and entanglement in moving parts.
PROPER USE OF TOOLS
Use tools appropriate to the work.
Makeshift tools and unfollowed
procedures can create safety hazards. Do
not use U.S mechanical tools on metric
fasteners (i.e. a 1/2 inch wrench on a 13
mm nut).
Use power tools only to loosen threaded parts and
fasteners. For loosening and tightening hardware,
use the correct size tools. Avoid bodily injury caused
by slipping wrenches. Use only service parts meeting
manufacturer specications.
PROPER LIFTING EQUIPMENT
Lifting heavy components incorrectly can cause severe
injury or equipment damage. Use expertise of staff
holding relevant(s) legal capacity to operate heavy
lifting equipment, with the know-how of using slings
and chains.
NOISE PROTECTION
Prolonged exposure to loud noise can
cause impairment or loss of hearing. Wear
a suitable hearing protective device such
as earmuffs or earplugs to protect against
objectionnable or uncomfortable loud
noises.
GENSET OUTPUT GENERATED POWER
SUPPORT ENGINES PROPERLY
Always lower the attachment or implement
to the base before you work on an engine.
If the work requires that the engine be
lifted, provide secure system. If left in a
raised position, hydraulically supported
device can settle or leak down. Do not
support engines on any kind of props that may crumble.
Do not work under an engine that is solely supported by
a jack. Follow recommended procedures in this manual.
SAFE ILLUMINATED WORK AREA
Illuminate your work area adequately and safely. Use a
portable safety light for working inside the engine room.
Make sure the bulb is enclosed by a wire cage. The hot
lament of an accidentally broken bulb can ignite spilled
fuel or oil.
Genset will deliver a sizeable amount of electrical power
which can be lethal if not handled properly. Thus, any
service, connection or repair on the alternator can only
done by a certied marine electrician.
GUARDS REQUIREMENTS
Rotating cooling system fans, belts,
pulleys, and drives can cause serious
injury. Keep all guards in place at all times
during the engine operation. Wear close-
tting clothes. Stop the engine and be sure that fans,
belts, pulleys, and drives are stopped before making
adjustments, connections, or cleaning near fans and
their drive components.
13
S02 SAFETY
STAYING CLEAR OF ROTATING
DRIVELINES
Entanglement in rotating driveline can
cause serious injury or death. Keep all
shields in place at all times. Make sure
rotating shields turn freely.
Wear close-tting clothing. Stop the engine and be sure
that all rotating parts and drivelines are stopped before
making adjustments, connections, or performing any
type of service on engine or driven equipment.
PAINT REMOVAL BEFORE HEATING
Avoid potentially toxic fumes and dust.
Hazardous fumes can be generated when
paint is heated by welding, soldering, or in
using a torch.
Paint removal :
• Remove paint a minimum of 100 mm (4 in.) from area
to be affected by heating. If paint cannot be removed,
wear an approved respirator mask before heating or
welding.
• If you sand or grind paint, avoid breathing the dust.
Wear an approved respirator.
• If you use solvent or paint stripper, remove stripper
with soap and water before welding. Remove solvent
or paint stripper containers and other flammable
material from area.
• Allow fumes to disperse at least 15 minutes before
welding or heating.
• Do not use a chlorinated solvent in areas where
welding will take place.
• Do all work in an area that is well ventilated to carry
toxic fumes and dust away.
• Dispose of paint and solvents properly.
HIGH-PRESSURE FUEL SYSTEM OPENING
RISK
High-pressure fluid remaining in fuel lines
can cause serious injury. Do not
disconnect or attempt repair of fuel lines,
sensors, or any other components
between the high-pressure fuel pump and
nozzles on engines with High Pressure
Common Rail (HPCR) fuel system. Only technicians
familiar with this type of system can perform repairs.
Consult your engine representative.
AVOID HIGH-PRESSURE FLUIDS
Inspect hydraulic hoses periodically – at
least once per year – for leakage, kinking,
cuts, cracks, abrasion, blisters, corrosion,
exposed wire braid or any other signs of
wear or damage. Replace worn or damaged
hose assemblies immediately with approved
replacement parts. Escaping fluid under pressure can
penetrate the skin causing serious injury.
Avoid the hazard by relieving pressure before
disconnecting hydraulic or other lines. Tighten all
connections before applying pressure. Search for leaks
with a piece of cardboard.
SAFE COOLING SYSTEM SERVICE
Explosive release of fluids from pressurized
cooling system can cause serious burns.
Shut off engine. Only remove ller cap
when cool enough to touch with bare
hands. Slowly loosen cap to rst stop to
relieve pressure before removing completely.
AVOID HEAT NEAR PRESSURIZED FLUID LINES
Flammable spray can be generated by heating near
pressurized fluid lines, resulting in severeburns to
yourself and bystanders. Do not heat by welding,
soldering, or using a torch near pressurized fluid lines or
other flammable materials.
Pressurized lines can accidentally burst when heat goes
beyond the immediate flame area.
Any fluid injected into the skin must be surgically
removed within a few hours or gangrene may result.
Doctors unfamiliar with this type of injury should
reference a knowledgeable medical source.
14
S02 SAFETY
WELDING NEAR ELECTRONIC CONTROL
UNIT (ECU)
If welding is required around the engine, or
in the engine room, ask rst for a
permission from the person in charge. Do
not jump-start engine with arc welding
equipment. Currents and voltages
delivered are too high and may cause permanent
damage. Direct welding onto the engine is forbidden.
1. Disconnect the negative (-) battery cable(s).
2. Disconnect the positive (+) battery cable(s).
3. Connect the positive and negative cables together.
Do not attach to engine support frame.
4. Clear or move any wiring harness sections away
from welding area.
5. Connect welder ground close to welding point and
away from control units.
6. After welding, reverse Steps 1-5.
STATIC ELECTRICITY RISK
HANDLE FUEL SAFELY - AVOID FIRES
Handle fuel with care: it is highly flammable. Do not
refuel the engine while smoking or when near open flame
or sparks.Always stop engine before refueling. Prevent
res by keeping engine room clean of accumulated
trash, grease, and debris. Always clean up spilled fuel.
Use only an approved fuel container for transporting
flammable liquids. Do not store fuel container where
there is an open flame, spark, or pilot light such as within
a water heater or other appliance.
BE PREPARED FOR EMERGENCIES
Be prepared if a re starts. Keep a rst aid kit and
re extinguisher handy. Keep emergency numbers
for doctors, ambulance service, hospital, and re
department near your telephone.
The removal of sulfur and other compounds in Ultra-Low
Sulfur Diesel (ULSD) fuel decreases its conductivity and
increases its ability to store a static charge. Reneries
may have treated the fuel with a static dissipating
additive.
However, there are many factors reducing the
effectiveness of the additive over time. Static charges
can build up in ULSD fuel while it is flowing through fuel
delivery systems. Static electricity discharge in presence
combustible vapors could result in a re or explosion.
Therefore, it is important to ensure that the entire system
used to refuel your engine (fuel supply tank, transfer
pump, transfer hose, nozzle, and others) is properly
grounded and bonded.
Consult your fuel or fuel system supplier to ensure
that the delivery system is in compliance with fueling
standards for proper grounding and bonding practices.
HANDLE STARTING FLUID SAFELY (ETHER)
Starting fluid is highly flammable. Keep all
sparks and flame away if using it. Keep
starting fluid away from batteries and
cables.
To prevent accidental discharge when storing the
pressurized can, keep the cap on the container, and
store in a cool, protected location. Do not incinerate or
puncture a starting fluid container. Do not use starting
fluid on an engine equipped with glow plugs or an air
intake heater.
HANDLING BATTERIES SAFELY
If not handled properly, batteries are a
potential source of hazards. Excess of
gases in batteries may explode. Keep
sparks and flames away from batteries.
Never use a cigarette lighter to observe
electrolyte level. Use a flashlight to do it. Never check
battery charge in shorting posts with a metal part. Use a
voltmeter or hydrometer.
15
S02 SAFETY
Always remove grounded (-) battery clamp rst and
replace grounded clamp last. Sulfuric acid in battery
electrolyte is poisonous and strong enough to burn skin,
eat holes in clothing, and cause blindness if splashed
into eyes.
Avoid hazards and acid burns in :
WARNING !
Battery posts, terminals, and related accessories contain
lead and lead compounds. Rinse hands after handling
batteries.
• Filling batteries in a well-ventilated area
• Wearing eye protection and rubber gloves
• Avoiding use of air pressure to clean batteries
• Avoiding breathing fumes when electrolyte is
• Avoiding spilling or dripping electrolyte
• Using correct battery booster or charger procedure.
If acid is spilled on skin or in eyes:
• Flush skin with water
• Apply baking soda or lime to help neutralize the acid
• Flush eyes with water for 15-30 minutes.
• Get medical attention immediately.
If acid is swallowed:
• Do not induce vomiting
• Drink large amounts of water or milk, but do not
exceed 2 L (2 qt.)
• Get medical attention immediately.
FROST PROTECTION-WINTERIZATION
See Maintenance Section 08 - Raw Water System - Risk
of icing conditions / Protection against frost.
WARNING !
When the engine has been set for winterization, place
“DO NOT OPERATE” labels onto taps, valves, parts of
equipment which have been turned off. Place a large and
visible reminder on the wheelhouse dashboard.
LIVE WITH SAFETY
Before returning engine to customer, make sure engine
is functioning properly, especially the safety systems.
Make sure that all guards and shields are in place.
PREVENT ACCIDENTS
IMPORTANT !
PREVENT BATTERY EXPLOSIONS
Keep sparks, lighted matches, and open
flame away from the top of battery. Battery
gas can explode. Never check battery
charge by placing a metal object across
the posts. Use a volt-meter or hydrometer.
Do not charge a frozen battery: it may
explode. Warm up battery to 16°C (60°F) before doing it.
When engine is OFF, always set the transmission lever to
neutral position.

DANGER !
Fuels and some fluids on board ships are easily
flammable. Handle fuels with care and respect all safety
rules. Do not refuel the tank while the engine is running.
Do not smoke during the lling process or in the engine
compartment. Ventilate the engine compartment before
starting. Wear protective gloves and eye protective
glasses. Avoid synthetic clothing which can melt when
ignited. Always keep a re extinguisher nearby.
DIESEL FUEL
Diesel approved by Nanni Industries on the engines of
the rm are as follows :
• EN 590 (Europe),
• ASTM D975 (U.S.A and territorial waters assimilated,
particularly in the Caribbean and Pacic areas),
• BS 2869 Part 1 Class A1 (G.B),
• JIS KS2204 Fuel N°02 (Japan).
These regulations are in compliance with ISO 8217 DMX.
SULPHUR CONTENT
European Union :
Low-sulphur diesel (<50 mg/kg sulphur) [EN590], or
sulphur-free (<50 mg/kg sulphur [DIN EN590], [ULSD].
Non-European Union :
Sulphur contained in diesel fuel not in accordance with
EN 590 regulation signicantly reduces the performance
of the engine lubricant. More frequent oil changes
are mandatory and also induce much shorter fuel
lter replacement intervals. Request a certicate of
specications from the fuel distributor and forward it
to the nearest Nanni local representative for advice and
action.
Fuels not intended for the operation of marine engines
or with very high sulphur content can cause irreparable
damage to the engine and are not covered by any
warranty from Nanni Industries.
WINTER DIESEL
Without specic mention, these distributed fuels satisfy
the climates in which they are geographically available.
Generally speaking, summer diesel fuel complying with
EN 590 is usable down to a temperature of 0°C [32°F],
and the winter formulated fuel, down to a temperature
of -20 °C [-4°F] (type No. 01-D in U.S.A). In any case,
consult your local distributor to ensure compatibility of
the fuel.
NOTE !
Additions of petroleum distillates, petrol, solvents,
unapproved additives to improve the fluidity of diesel
fuel at very low temperatures can cause irreparable
engine damage and will void all contractual warranties
and responsabilities from Nanni Industries.
WATER IN FUEL
Water is a non-flammable and incompressible liquid.
For this reason, its presence is particularly harmful
to the operation of the engine and to the entire fuel
injection system. Water easily enters the tank by simple
condensation and especially when it is left or partially
empty. Fill up the fuel tank before storage/winter storage.
Check the water-diesel separator regularly and clean it
as required. Anticipate the replacement of the fuel lter.
If a large quantity of water is present in the tank, drain it
and flush the entire fuel and injection system with clean
diesel fuel. Water in the diesel fuel can cause irreparable
damages to the engine and are not covered by any
warranty from Nanni Industries.
MICROORGANISMS IN FUEL
The presence of water in the tank automatically leads
microorganisms and bacteria to grow and will mix with
the fuel. These microorganisms grow rapidly with a
favorable temperature. Depending on their size, they can
pass through lters and penetrate in the fuel injection
system and cause a total engine failure which is not
covered by Nanni Industries warranty. In the event of
fuel contamination, contact the nearest Nanni agent
who may, if necessary, use an approved disinfectant.
18
S03 FLUIDS
INERT IMPURITIES IN FUEL
Others impurities than microorganisms and bacteria do
exist : they are rust debris falling out from the internal
walls of the metal tanks. Some types of berglass tanks
are also subject to osmosis over time and tiny particles
may come off internal walls and circulate in the diesel
fuel. These impurities can pass through the lters and
creep into the injection system and cause a total failure
of the engine which is not covered by Nanni Industries
warranty.
DIESEL LUBRICANTS
PRECAUTIONS TO UNDERTAKE
Engine oils must be handled with care, both for reasons
of safety and the risk of pollution for the environment.
Due to their inertia, hot oils retain a higher temperature
than expected. A hot oil can cause severe burns on
the skin and leave after effects. This phenomenon is
emphasized when draining used oil. Wear protective
gloves and eye protective glasses. Avoid synthetic
clothing.
To avoid introducion of impurities into the engine
during lling or topping up, be sure to thoroughly clean
the ller inlet hole rst and use a container free of any
contamination.
OILS RECOMMENDED OR AUTHORIZED
It is necessary to differentiate the breaking-in oils
from the lubricating oils after running-in. All engine
manufacturers do not have the same recommendations.
User manuals provide information about proper oils
to use for running-in (if recommended) and at which
running hours and of time lapse of run.
GENERALITIES
The oil used in the engine must have a viscosity in
accordance with the ambient temperatures at which
the engine is operated, according to API (American
Petroleum Institute) and SAE (Society of Automotive
Engineers) classications.
Following the entry into force of strict antipollution
regulations, engine oils have been developed for use
with low sulphur fuels (LSD or ULSD). The oils classied
“CF” being now obsolete, use oils “CJ-4, CI-4, CH-4”.
The oils “CH-4” do come in replacement of the “CD, CJ,
CF-4 and CG- 4“. In all cases, the use of high sulphur
fuel signicantly reduces the span between oil changes
whichever oil is used.

OILS VISCOSITY
Viscosity is a characteristic of oil flow or fluidity, dened
by two numbers: cold and hot. Example :
15W-40: cold viscosity index followed by the letter W
signifying winter. A low value indicates good fluidity at
low temperatures.
15W-40: hot viscosity index (100 °C - summer). A high
value indicates a better lubrication at hot temperatures.

DIESEL SULPHUR CONTENT
NOTE
Diesel sulfur content affects engine oil and lter service
intervals.
Normative instances :
• Society of Automotive Engineers (SAE),
• American Petroleum Institute (API),
• Association des Constructeurs Européens
d’Automobiles (ACEA),
• Japanese Automobile Manufacturer Association
(JAMA).
IMPORTANT !
On manufacturers side, oils are subject to constant
improvements, particularly concerning the additives
allowing a better resistance towards oxydation and
fuel economy. Refer to the expertise of the local Nanni
Industries representative regarding the oil that best
suits your engine.
Use of diesel fuel with sulfur content less than 2000 mg/
kg (2000 ppm) is RECOMMENDED.
Use of diesel fuel with sulfur content of 2000-5000 mg/
kg (2000-5000 ppm) REDUCES by 50% the oil and lter
change interval.
Do not use diesel fuel with sulfur content greater than
5000 mg/kg (5000 ppm).
IMPORTANT !
To avoid engine damage:
• Reduce oil and lter service intervals by 50% when
using BioDiesel blends greater than B20. Oil analysis
may allow longer service intervals.
• Use only approved oil types.

COOLANTS
WARNING !
Products not fullling the demands in this section may
lead to faults and damage occurring in the cooling
system. This can lead to the invalidation of Nanni’s
warranty for faults and damage caused by the use of
inappropriate coolant.
COOLANT DRAIN INTERVALS
Drain and flush the cooling system of the engine and
rell with fresh coolant at the indicated intervals, which
depends of the coolant used and of the maintenance
schedule service of the engine.
WATER PROPERTIES
Water properties are important to the efciency of the
cooling system. Distilled, deionized, or demineralized
water is recommended for mixing with ethylene glycol
or propylene glycol base engine coolant concentrate.
WATER PROPERTIES TO MIX WITH
COOLANT CONCENTRATE
Engine coolants are a combination of three chemical
components: ethylene glycol (EG) or propylene glycol
(PG) antifreeze, inhibiting coolant additives, and
adequate “quality” water.
Do not use bottled drinking water as it often contains
higher concentrations of dissolved solids.
Water used in the cooling system should meet the
following minimum specications for quality :
Chlorides < 40 mg / L
Sulfates < 100 mg / L
Total dissolved solids < 340 mg / L
Total hardness < 170 mg / L
pH 5,5-9,0
When mixing coolant concentrate with water, do not
use less than 40 % or greater than 60 % concentration
of coolant. Less than 40 % is inadequate for corrosion
protection. Greater than 60 % can result in coolant
gelation (solidication by cooling) and cooling system
problems. As a general rule, a mixing of 50/50% is
preferred whenever possible.
IMPORTANT !
• Do not use cooling system sealing additives, neither
antifreeze containing sealing additives.
• Do not mix ethylene glycol and propylene glycol base
coolants together.
• Do not mix coolants of various brands and makes
together.
• Do not use coolants containing nitrites.

S03 FLUIDS
OTHER COOLANTS
Other ethylene glycol or propylene glycol base coolants
may be used if they meet the following specication :
• Pre-mix coolant meeting ASTM D6210 requirements.
• Coolant concentrate meeting ASTM D6210
requirements in a 40-60 % mixture of concentrate
with appropriate water.
If coolant meeting one of these specications is
unavailable, use a coolant concentrate or pre-mix
coolant that has a minimum of the following chemical
and physical properties :
• Provides cylinder liner cavitation protection
according to a proven and recorded method or a fleet
study run at or above 60 % load capacity.
• Is formulated with a nitrite-free additive package.
• Protects the cooling system metals (cast iron,
aluminum alloys, and copper alloys such as brass)
from corrosion.
FREEZE PROTECTION
The relative concentrations of glycol and water in the
engine coolant determine the freezing protection limit.

COOLING SYSTEM CAPACITY
See ANNEX 1: VOLUME OF GLYCOL
OPERATING ENGINE IN WARM
TEMPERATURE CLIMATES
Nanni engines are designed to operate with
recommended engine coolants quoted in this chapter.
Always use a recommended engine coolant, even when
operating in geographical areas where freeze protection
is not required (internal engine corrosion protection).
IMPORTANT !
Tap clean water may be used as coolant substitute in
emergency situations only. Contact a Nanni represent-
ative as soon as it is possible for assistance. Get this
water flushed as soon as possible.
Running the engine with water only will make this substitute coolant to foam, aluminum and iron parts of the
engine will be subject to fast internal corrosion, along
with scaling, and cavitation occurances, even with cool-
ant conditioners.
IMPORTANT !
DO NOT use a coolant-water mixture greater than 60%
ethylene glycol or 60% propylene glycol. Refer to the
table below :
Ethylene Glycol Freeze protection limit
40% -24°C (-12°F)
50% -37°C (-34°F)
60% -52°C (-62°F)
Propylene Glycol Freeze protection limit
40% -24°C (-12°F)
50% -37°C (-34°F)
60% -52°C (-62°F)
When cooling system has been drained from the engine,
rell with recommended coolant as soon as possible.

DISPOSING OF WASTE FLUIDS
Prior to contemplate any draining, make sure that all
adequate gear such as : funnel(s), hose(s), suitable
container(s) and so on, are at hand.
Use leakproof containers when draining fluids. Do not
use food or beverage containers that may mislead
someone into drinking from them.
Wear gloves and eye protection glasses. Follow all safety
rules. Wait for engine to cool down.
Do not let waste to drip on the ground, down a city drain,
or into any water source. Improperly disposing of engine
coolants, oils, or other chemical fluids is a threat against
environment and is an offence in many countries.
Inquire on the proper way to recycle
or dispose of waste from your local
environmental or recycling center, or
from your Nanni engine representative or
service dealer.
