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.
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 leak-proof 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.
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.

14
S02 SAFETY
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 self-
propelled equipment, disconnect battery ground (-)
before making adjustments on electrical systems or
welding.
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 short-cuts
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.
SERVICE ENGINES SAFELY
Tie long hair behind your head. Do not wear
a neck tie, 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
jewellery 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 specications..
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.
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.

15
S02 SAFETY
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
objectionable or uncomfortable loud
noises
GENSET OUTPUT GENERATED POWER
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 certied 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.
STAYING CLEAR OF ROTATING DRIVE LINES
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 drive lines 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.

16
S02 SAFETY
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 severe burns 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.
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
The removal of sulphur and other compounds in
Ultra-Low Sulphur Diesel (ULSD) fuel decreases its
conductivity and increases its ability to store a static
charge. Reneries 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 vapours 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 fuelling
standards for proper grounding and bonding practices.
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 refuelling.
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.

17
S02 SAFETY
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.
Never Use it on Genset
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.
Use a flashlight to do it. Never check battery charge
in shorting posts with a metal part. Use a voltmeter or
hydrometer.
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 :
• 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.
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.
Battery posts, terminals, and related ac-
cessories contain lead and lead com-
pounds. Rinse hands after handling bat-
teries.
FROST PROTECTION - WINTERIZATION
See Maintenance Section 08 - Raw Water System - Risk
of icing conditions / Protection against frost.
When the engine has been set for winter-
ization, 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.

18
S02 SAFETY
LIVE WITH SAFETY

STORING FUEL
DANGER !
Fuels and some fluids on board ships are easily flamma-
ble. 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 compart-
ment. 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.
If there is a very slow turnover of fuel in the fuel tank or
supply tank, it may be necessary to add a fuel conditioner
to prevent water condensation. Contact your NANNI deal-
er for proper service or maintenance recommendations.
DIESEL FUEL
Consult your local fuel distributor for properties of the
diesel fuel available in your area.
In general, diesel fuels are blended to satisfy the low tem-
perature requirements of the geographical area in which
they are marketed.
Diesel fuels specied to EN 590 or ASTM D975 are recom-
mended. Renewable diesel fuel produced by hydro-treat-
ing animal fats and vegetable oils is basically identical
to petroleum diesel fuel. Renewable diesel that meets EN
590, ASTM D975, or EN 15940 is acceptable for use at all
percentage mixture levels..
Required Fuel Properties
In all cases, the fuel shall meet the following properties:
• Cetane number of 40 minimum. Cetane number
greater than 47 is preferred, especially for tempera-
tures below –20 °C (–4 °F) or elevations above 1675
m (5500 ft.).
• Cloud Point should be below the expected lowest
ambient temperature or Cold Filter Plugging Point
(CFPP) should be a maximum 10°C (18°F) below the
fuel cloud point.
• Fuel lubricity should pass a maximum scar diame-
ter of 0.52 mm as measured by ASTM D6079 or ISO
12156-1. A maximum scar diameter of 0.45 mm is
preferred.
• Diesel fuel quality and sulfur content must comply
with all existing emissions regulations for the area
in which the engine operates. DO NOT use diesel fuel
with sulfur content greater than 10 000 mg/kg (10
000 ppm).
E-Diesel fuel
DO NOT use E-Diesel (Diesel fuel and ethanol blend).
Use of E-Diesel fuel in any NANNI engines may void the
machine warranty
CAUTION !
Avoid severe injury or death due to the re and explosion
risk from using E-Diesel fuel.
Sulphur Content for Tier 3 and Stage III A Engines
• Use of diesel fuel with sulphur content less than 1000
mg/kg (1000 ppm) is RECOMMENDED.
• Use of diesel fuel with sulfur content 1000—2000
mg/kg (1000—2000 ppm) REDUCES the oil and lter
change interval.
• BEFORE using diesel fuel with sulfur content greater
than 2000 mg/kg (2000 ppm), contact your NANNI
