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

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

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. From the main IVECO MOTORS control panel: turn the
key switch to the rest position 8A.
B. From the secondary IVECO MOTORS control panel:
press the red STOP button (8).
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 in the relevant paragraph.
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. START button (11) and release it when the engine has started,
making sure that the instruments with analogue displays are
showing plausible values.

Operation
When the key switch is turned to position 8B an efficiency test will be
performed on all the indicator lights, lasting 5 seconds, with the
exception of the “Pre-lubrication”, “Pre-post heating”, “EDC electronic
injection 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 stopped.
Alpha-numeric display
This provides the following information:
• engine running speed
• total running hours (see note A)
• exhaust gas temperature (on request)
• instant fuel consumption (see note B)
The information required is selected by pressing the “Scroll select”
button on both the control panels, main and secondary.

(A)The control panel's internal electronics are programmed to count
the working hours and issue warnings when the time limit for
ordinary maintenance operations expires; this function requires
that the counter be reset after each maintenance operation, which
is carried out from the main control panel as follows:
- Pressing and holding the “Prog” (9) and “Scroll select” buttons (10),
turn the key switch from position 8A to position 8B and wait for
the display to show the pre-set value (e.g: 600 hours). Release the
buttons and press the “Prog” (9) button again once only to start
the new count.
