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 described.
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.

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; sudden acceleration may result in very smokey
exhaust.
The maximum cruising speed must not be more than 90% of the
speed corresponding to maximum power (see 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.

17
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 comply with the WARNINGS provided. Should it be necessary
to replace the batteries, 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.

18
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.
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 (EN590 standards). Do
not use additives. Do not use fuels derived from the synthesis of
organic substances and vegetable oils (Biodiesel).
Low temperature diesel
EN590 specifications distinguish different classes of diesel fuel,

When working in the engine compartment, pay particular attention
to how you move, to avoid contact with moving parts or high
temperature components.
Wear goggles and use high pressure air jets (maximum air pressure
used to clean is 200 kPa (2 bar, 30 psi, 2 kg/cm2).
Wear a protective helmet when working in an area were there are
suspended loads or systems installed at head-height.
Use protective hand cremes.
Immediately replace wet overalls.
