 GENERAL INFORMATION

GUARANTEE

In order to ensure that your engine gives the best possible performance

and to take advantage of the IVECO MOTORS guarantee, you must

follow the indications provided in this publication with great care; failure

to do so may result in invalidation of the guarantee.

SPARE PARTS

Always use Original IVECO MOTORS Spare parts. This is essential to

keep the engine in original running order.

The use of non-original spare parts will not only invalidate the guarantee,

but will mean that IVECO MOTORS will not be considered liable in any

way during the whole working life of the engine.

LIABILITY

The Manufacturer will only be considered liable subject to performance

of the control and maintenance operations indicated and described in

this manual; to this effect, proof that these operations have been

performed must be provided. Any special maintenance operations that

may be necessary must be carried out by qualified technicians from

authorised Workshops in the IVECO MOTORS Network, using the

instruments and equipment provided for the purpose.

SAFETY

The following information is intended to encourage caution when using

the engine, so as to avoid damage to persons or property as a result of

improper or incorrect behaviour.

The engines must only be used for the purposes indicated by the

Manufacturer.

Any tampering, modification and use of non-original spare parts

may compromise proper operation of the engine and safe

navigation;

never, under any circumstances

make

modifications to the

wiring and to the units equipping the engine,

or connect them to other power systems.

Pay particular attention to moving parts of the engine, to high

temperature components and to circuits containing pressurised

fluids; its electrical equipment houses electrical currents and

voltage.

The exhaust fumes produced by the engine are bad for your health.

The engine must only be moved using suitable lifting tackle, making

use of the U-bolts provided on the engine for that purpose.

The engine must not be started up and used until the vessel in

which it installed has satisfied all necessary safety requirements, or

until the vessel has been guaranteed to comply with local laws and

regulations.

The operations required to guarantee the best possible use and

preservation of the engine must only be carried out by persons of

proven experience, equipment with tools considered suitable by

IVECO MOTORS.

For the purpose of safety, further recommendations are given in the

chapter CONTROLS AND MAINTENANCE.

 USE

PRELIMINARY CHECKS

Before starting the engine each time:

Make sure that the sea-water inlet valve is open. Operation of the

sea water pump without water would cause irreparable damage to

the internal rotor within a very few seconds.

Check the level of technical fluids (fuel, engine oil and coolant).

STARTING AND STOPPING THE ENGINE

For vessels equipped with instrument panels that

are not manufactured by IVECO MOTORS

The start-up and shut-down operations described below apply to an on-

board control panel manufactured by IVECO MOTORS; if the vessel is

fitted with an instrument panel that has been customised by the

Boatbuilder or Fitter, these operations may vary according to the various

choices made during construction. In these cases, follow the start-up/

shut-down sequence and use the instrument panel description provided

by the Boatbuilder on specific documentation.

CAUTION!

Before starting the engine, make sure that no

combustible vapours or gasses are present in the

engineroom.

Stopping the engine

Before stopping the engine it is recommended you run it for a few

minutes at minimum speed with no load; this will allow the temperature

to drop evenly and will avoid harmful thermal shocks.

A. The engine is normally stopped from the main IVECO MOTORS

control panel by turning the key switch to the rest position 8A or

by turning a similar command on the customised control panel.

B. The IVECO MOTORS secondary control panel is stopped by

pressing the red button (6) on the control panel.

The main IVECO MOTORS control panel for engines equipped with an

“excited” device (on request or as prescribed by the Certification

Body), is stopped by pressing the red button (9).

To re-start the engine from the main control panel:

1. Return the key switch to the rest position 8A to reset all the on-

board control panel functions.

2. Proceed as indicated.

To re-start the engine from the secondary control panel:

1. Make sure that the panel has been enabled (key switch on the main

control panel turned to position 8B).

2. Press the green button (5) and release it when the engine has

started, making sure that the rev indicator is showing a plausible

reading.

ENGLISH

RECOGNISING ALARMS

IVECO MOTORS on-board control panels with analogue instruments

are fitted with an electronic module that includes the indicator lights and

the interface, timer and alarm storage circuits.

The figure illustrates the dial and the key indicates the meaning of the

alarm signals sent by all the indicator lights; some types of engine and

relevant equipment only make some of the above mentioned functions

available.

If the Boatyard uses different technical options there may also be

changes to the above.

Operation

When the key switch is turned to position 8B the signals and alarms

module will perform an efficiency test on all the indicator lights, lasting 5

seconds, with the exception of the “Pre-lubrication”, “Pre-post heating”,

“EDG system malfunction” indicators, and simultaneously the beeper

sounds.

It is possible to stop the beeper before the end of the test, by pressing

the relevant button.

During start-up and for the following 15 seconds, all alarm functions are

disabled; after this period, each alarm detected by the sensors provided

on the engine will result in the relevant indicator flashing and a

simultaneous warning sound from the beeper. If the beeper is disabled

by pressing the relevant button, the indicator light will turn on without

flashing and the alarm will be stored until the engine is next stopped.

1. Maximum allowed rotation speed exceeded (on request) - 2. Water

FOR PROPER USE OF THE ENGINE

Do not continue to press the starter, when the engine has started.

Do not remain in dock while waiting for the engine to warm up,

but after starting, commence navigation at low speed; the working

temperature will be reached properly with the engine running at

medium speeds.

Do not operate the engine at minimum speed for long periods, as

this encourages the production of harmful exhaust and does not

guarantee optimum performance.

The engine speed must be increased and decreased gradually, to

allow regular combustion and proper operation of all engine

components.

The maximum cruising speed must not be more than 90% of the

speed corresponding to maximum power (see section on ENGINE

TECHNICAL DATA).

During navigation, check that:

• The engine coolant temperature does not reach the alarm

threshold.

• The oil pressure remains within normal values.

SPECIAL WARNINGS

Coolant temperature high

If the temperature indicated on the instrument is considered too high,

or if the alarm is displayed, reduce speed and return to port to check

the state of the sea water intake and cooling system circuits; also check

and have checked:

• tension of the water pump and alternator command belts.

• operation of the thermostat valve.

• whether or not the heat exchangers are clean.

Low lubricant pressure

If the pressure indicated by the instrument is considered insufficient, or

if the “low oil pressure” indicator lights up, stop the engine and check

the oil level. Top up if necessary (see CONTROL AND

MAINTENANCE section).

If the condition persists, return to port at low speed and contact an

Authorised Service Centre.

CAUTION!

When the engine is warm, a pressure liable to cause

hot liquid to be expelled with extreme violence is

created within the cooling circuits. This results in a

danger of burning. Only open the coolant tank cap if

strictly necessary, and only when the engine is cold.

ENGLISH

Water in the fuel pre-filter

It is a good rule to drain the water from the filters, before the relevant

indicator comes on.

Avoid using the engine with the fuel tank only a small reserve of fuel; this

encourages the formation of condensation and makes it more likely you

will suck up dirt or air, resulting in engine stoppage.

Air filter blocked and exhaust circuit inefficient

Inspect the cleanliness of the air intakes and discharge pipes on a regular

basis. The maintenance intervals indicated in this manual only take into

account the performance of engine components, and not any additional

fittings installed by the Boatbuilder and any external events.

Alternator malfunction

Check it or have it checked periodically for cleanliness, wear and proper

tensioning of the drive belt.

Irregularities in the electrical system

Periodically check, particularly during the winter, to ensure that the

batteries are clean and in full working order, checking and topping up as

indicated in the section CONTROLS AND MAINTENANCE, always

taking due note of the WARNINGS provided. If it should be necessary

to replace them, always comply with the characteristics indicated in the

section ENGINE TECHNICAL DATA.

RUNNING IN

Thanks to modern engine construction technology, no particular running

in procedure is required. However, it is recommended that, for the first

50 hours, you do not use the engine at high power for long periods.

CAUTION!

When refuelling, always pay great care to ensure that

no solid or liquid pollutants enter the fuel tank; you

must also remember that smoking and live flames are

prohibited when refuelling.

CAUTION!

Visually check that the exhaust circuit is not blocked or

damaged, so as to prevent dangerous fumes within the

vessel.

CAUTION!

The drive members are located under protective

casings. These must only be removed when the engine

is not turning.

REFUELLING

(I)Use a mixture of water and 50% PARAFLU 11 even during the

summer months. As an alternative to PARAFLU 11, you can use another

product that complies with international specifications SAE J 1034.

(2) Use lubricants that comply with international specifications ACEA

E3 - E5 (high power engines), API CF - CH4 (associated with fuels

with a percentage sulphur < 0.5%), MIL - L - 2104 F.

The viscosity level of oil to be used depending on surrounding

temperatures in given in the table provided in the appendix.

Oil consumption is considered acceptable when it reaches a

maximum of 0.5% of fuel consumption.

(3)The amounts indicated refer to initial refuelling, and include filling

the engine, sump and filter.

(4)Only use normal commercial diesel fuel (EN 590 standards). Do

not use additives. Do not use fuels derived from the synthesis of

organic substances and vegetable oils (Biodiesel).

Low temperature diesel

EN 590 specifications distinguish different classes of diesel fuel,

identifying the characteristics of those best suited to low temperatures.

It is entirely up to the Oil companies to comply with these regulations,

which foresee that fuels suited to the climactic and geographic

conditions of the various Countries be distributed.

cables supporting the engine parallel, using all the U-bolts provided

simultaneously; the use of a single U-bolt only is not allowed.

The engine lifting system must have a capacity and size suited to the

weight and dimensions of the engine; check that there is no interference

between the lifting system and the engine components.

Do not lift the engine before removing the transmission members that

are coupled to it.

DISPOSAL OF WASTE

The engine is made up of parts and elements that, if discarded, may

cause damage to the environment.

The materials listed below must be handed over to specialised

Collection Centres; the laws in force in the various Countries foresee

severe penalties for transgressors:

Starter batteries.

Used lubricants.

Mixtures of water and antifreeze.

Filters.

Additional cleaning materials (e.g. greasy or fuel-soaked cloths).

 LONG PERIODS OF INACTIVITY

PREPARING THE ENGINE FOR A LONG

PERIOD OF INACTIVITY

In order to prevent oxidation of the internal parts of the engine and of

certain components in the injection system, when the engine is

expected to be inoperative for periods of more than two months, the

following operations must be carried out in preparation for this:

1. Drain the lubricant from the sump, after first warming up the

engine.

2. Fill the engine with protective oil type 30/M (or alternatively oil that

complies with MIL 2160B type 2 specifications), up to the

"minimum" level indicated on the dipstick. Start the engine and keep

it running for approximately 5 minutes.

3. Drain the fuel from the injection circuit, from the filter and from the

injection pump pipes.

4. Connect the fuel circuit to a tank containing CFB (ISO 4113)

protective fluid, and feed in the fluid by putting the circuit under

pressure and running the engine for approximately 2 minutes, after

first disabling the injection system. This operation can be performed

by polarising terminal 50 of the starter motor with a positive

voltage equivalent to the rated voltage of the system, using a

conductor provided for that purpose.

5. Nebulise approximately 60 g of 30/M protective oil (10 g per litre

displacement) into the turbocompressor suction inlet, during the

pressurised filling operation described in the previous point.

6. Close all the suction, delivery, ventilation and bleeder openings in

the engine with suitable plugs, or seal them with adhesive tape.

7. Drain the residual 30/M protective oil from the sump. This oil can

be used again for a further 2 preparation operations.

8. Fit signs reading ENGINE WITHOUT OIL to the engine and to the

on-board control panel.

9. Drain the coolant, if it has not been mixed with suitable antifreeze

and corrosion inhibitors, and affix a sign to indicate the fact.

In the event of prolonged inactivity, the operations described must be

repeated every 6 months, following the procedure given below:

A) drain the 30/M protective oil from the sump;

B) repeat the operations described from point 2 to point 7.

Should you intend to protect external parts of the engine, proceed by

spraying OVER 19 AR protective liquid on unpainted metal parts, such

as the flywheel, pulleys and the like, avoiding belts, connector cables and

electrical equipment.

ENGLISH

RESTARTING THE ENGINE AFTER A LONG

PERIOD OF INACTIVITY

1. Drain the residual 30/M protective oil from the sump.

2. Fill the engine, as prescribed, with lubricant of the type and amount

indicated in the table REFUELLING.

3. Drain the CFB protective fluid from the fuel circuit, carrying out this

operation as indicated under point 3. of PREPARING THE

ENGINE FOR A LONG PERIOD OF INACTIVITY.

4. Remove the plugs and/or seals from the suction, delivery,

ventilation and bleeder openings in the engine, restoring it to a

normal state of use. Connect the turbocharger suction inlet to the

air filter.

5. Connect the fuel circuits to the vessel’s fuel tank, completing the

operations as indicated in point 4. of PREPARING THE ENGINE

FOR A LONG PERIOD OF INACTIVITY. During filling operations,

connect the fuel return pipe to a collection tank, so as to prevent

any residual CFB protective fluid from flowing into the vessel’s fuel

tank.

6. Check the engine and fill it up with coolant as prescribed.

7. Start the engine and keep it running until the idling speed rate has

stabilised completely.

8. Check that the instruments on the on-board control panel/s are

showing plausible values, and that no alarms are shown.

9. Stop the engine.

10.Remove the ENGINE WITHOUT OIL signs from the engine and

from the on-board control panel.

 ENGINE MALFUNCTIONS

The electronic unit overseeing management and control of all operation

of the engine is capable of recognising any malfunctions that may occur,

and of adopting strategies that will allow you to navigate in full safety.

The event, signalled by light-up of the EDC MALFUNCTION indicator

on the on-board control panels, results in programmed limitation of

power within certain thresholds, set according to the severity of the

case.

In the case of temporary malfunctions the reduction in performance will

remain in force until the engine is stopped.

Accelerator electronic circuit malfunction

When certain problems in the accelerator electric circuit are recognised,

the Electronic Unit controlling the engine adopts a strategy known as

“accelerated minimum speed running”, that will enable navigation to

continue in emergency mode.

The possible operating modes are as follows:

A. The accelerator lever does not “respond”: the running speed

stabilises at 750 rpm. to allow the vessel to proceed slowly and be

manouevered simply by turning the marine gear on and off, with-

out accelerating.

B. The accelerator lever “responds partially”: the minimum running

speed is set to 750 rpm. When the accelerator lever is moved to

approximately half way, the speed gradually increases up to 2000

rpm.; when the lever is returned to minimum the speed rapidly

decreases to 750 rpm.

NOTE: In mode “A” it is possible to proceed at speeds higher than the

accelerated minimum, managing start/stop, acceleration and

deceleration functions as illustrated in the section MANAGING THE

ENGINE FROM THE RELAY BOX. Should it be necessary to operate

the engine as above, always comply with the accident

prevention rules provided in the Section “Controls and

maintenance.

CAUTION!

The engine electronic control unit can adopt safety

strategies at any time during navigation, should

conditions arise that are considered to put the engine

at risk.

When conditions of this kind occur, proceed with the

greatest possible care and attention, first making sure

that all those on board are secure and holding on to

safe hand-holds.

CAUTION!

Management of the engine from the “Relay box”

involves inhibition of the bridge controls; as a result of

this, when running the vessel from the bridge, the

only way to stop propeller thrust in the engine

quickly is using the marine gear disengagement lever.

ENGLISH

 EMERGENCIES ON BOARD

The user of a vessel that has been constructed according to safety

regulations, when following the instructions provided in this manual and

the indications given on the engine labels, will be working in safe

conditions.

Should improper conduct result in accidents, always request the

intervention of trained first aid specialists immediately.

In an emergency and while awaiting the arrival of first aid specialists,

follow the instructions given below.

Engine malfunctions

When navigating with a malfunctioning engine, take the greatest possible

care when manouevering and make sure that all those aboard are

holding firmly to safe hand-holds (see section on ENGINE

MALFUNCTIONS).

In case of fire

Extinguish the fire using the fire-fighting equipment provided aboard, and

in the manner indicated by Fire prevention authorities (the fire-fighting

equipment required on board is compulsory under current safety

legislation).

Burns and scalds

1. Extinguish any flames on the burned person's clothing, by:

• throwing water over them;

• using a powder fire-extinguisher, without directing the jet at the

person's face;

• covering with blankets or rolling the victim on the ground.

2. Do not attempt to remove pieces of clothing that may have stuck

to the skin;

3. In the case of scalding, immediately but carefully remove any

clothing that may be soaked in the hot liquid;

4. Cover the burn with a special burn dressing or sterile bandage.

Carbon monoxide intoxication (CO)

Carbon monoxide from the engine exhaust is without smell, and is

dangerous both because it causes intoxication, and because when

combined with air it forms an explosive mixture.

In closed rooms, carbon monoxide is extremely dangerous, as it can

reach critical concentrations within a very short time.

When assisting an intoxicated person in a closed room:

1. Ventilate the room immediately, to reduce the concentration of

gas.

2. When entering the room, hold your breath, do not light flames,

lights or ring electric doorbells or phones, to avoid the risk of

explosion.

3. Carry the intoxicated person out into the fresh air or into a well

ventilated room, resting him on one side if he is unconscious.

Electrocution

The engine's electrical 12 V or 24 V electrical system does not involve

the risk of electrocution, however, in the event of a short-circuit caused,

for example, by a metal tool, there is a risk of burning due to overheating

of the object through which the electrical current runs. In these

circumstances:

1. Remove the object that caused the short-circuit, using means that

provide sufficient heat insulation.

2. Switch off the power at the main switch, if there is one.

Injuries and fractures

The vast number of possible circumstances and the specific nature of

operations required means that the intervention of a medical team is

necessary.

1. In the event of bleeding, keep the edges of the wound pressed

together until help arrives.

2. If there is any suspicion of a fracture, do not move the injured part

and only move the patient if absolutely necessary.

Caustic burns

Caustic skin burns are caused by contact with extremely acid or alkaline

substances.

For electric maintenance technicians these are typically caused by acid

from batteries; in these circumstances, proceed as follows:

1. Remove any clothing soaked in the caustic substance.

2. Wash the area with lots of running water, avoiding parts that have

not been burned.

If either battery acid, lubricants or diesel come into contact with the

eyes: wash the eyes with water for at least 20 minutes, keeping the

eyelids open so that the water flows over the eyeball (move the eye in

all directions to wash more thoroughly).
