INTRODUCTION
We would like to thank you for buying an IVECO MOTORS product,
and compliment you on your choice of engine.
Before you carry out any operation involving the engine or its fittings,
please read the contents of this manual carefully; compliance with the
instructions provided in the manual is the best way to guarantee troublefree, long term operation of the engine.
The contents of this manual refer to the standard configuration of the
engine, and the illustrations are purely indicative. Some instructions are
provided by giving the sequence of operations to be carried out in order
to allow the engine and/or its fittings to perform in a certain way. In
some cases they will be dependent on the configuration of the
commands and the set-up of the vessel on which the engine is installed;
for any points that differ from the contents of this manual, please consult
the instructions provided by the Boatbuilder or a specific manual.
The information provided below was current at the date of publication.
The Manufacturer reserves the right to make modifications at any time
without prior notice, for technical or commercial reasons or to update
the engines to comply with legal requirements in the various Countries.
The Manufacturer declines all liability for any errors or omissions.
Please remember that the IVECO MOTORS Technical Service
Network is available to offer you its experience and professional skills,
wherever you may be.

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;
modifications to the
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.

SIGNS
Certain warning signs are affixed to the engine, and their meanings are
indicated below.
NOTE: The signs with an exclamation mark on them underline a
potential danger.
Lifting point (engine only).
Fuel Cap
(on the fuel tank, if there is one).
Oil Cap.
Oil dipstick.
Danger of burning:
Expulsion of hot water under pressure.
Danger of burning:
Presence of high temperature parts.
Danger of fire:
Fuel present.
Danger of impact or catching
on moving parts:
Presence of fans, pulleys, belts or the like.

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).
CAUTION!
Before starting the engine, make sure that no
combustible vapours or gasses are present in the
engineroom.
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 onboard 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.

STARTING AND STOPPING THE ENGINE
FROM THE ANALOGUE CONTROL PANEL
Procedure for start-up from the main IVECO
MOTORS control panel (supplied on demand)
Make sure that the electrical switch indicating ENGINE ROOM BRIDGE on the Relay Box unit (normally located in the engine room) is
in the BRIDGE position, then proceed as follows:
1. Lift the protective cover over the key switch (8), insert the key and
turn it to the right to position 8B.
2. Make sure that the analogue instruments are showing values that
conform with the relevant physical parameters (temperature,
battery voltage and oil pressure).
3. Wait for the beeper to stop sounding and for the alarm indicator
lights on the indicator module (5) to switch off, with the exception
of the “alternator recharge” and “low oil pressure” indicators. At
the same time, check that the indicator test has been performed
successfully (information on how to interpret this test and
indications on the module are given in the relevant paragraph).
4. Turn the key to position 8C; once the engine has started, release
the key and do not accelerate.
5. Make sure that the analogue instruments are showing values that
conform with the relevant physical parameters (temperature,
battery voltage and oil pressure).
6. If the engine does not start, after releasing the key it will only be
possible to turn it back to the start position after first returning the
switch to the rest position 8A.
