2. WARNINGS AND CAUTIONS

To obtain the best engine performance, it is essential not to
deviate from the mission profile for which it was produced
and set up.The engine must not be used for purposes other
than those stated by the manufacturer. IVECO MOTORS
is willing to examine any need for particular installations
beforehand. Boat outfitters and maintenance specialists
are invited to closely follow the instructions contained
herein. No modifications to the engine, its accessories and
components, are allowed.
Failure to comply with the instructions that follow shall
void the warranty and relieve iVecO MOTOrs of all
liabilities.
For personnel safety
specialists and installers are cautioned to comply with
workplace safety rules and to adopt prescribed individual
protection devices when working.
o Drain the cooling, lubrication and fuel lines only after
the fluids have duly cooled. The pressurized cap of the
water line may be opened only after the engine has duly
cooled.
o Batteries contain a highly corrosive sulfuric acid solution:
must never be upset and must be handled with the
utmost caution to prevent spillage. Ensure that the bat-
tery compartment is adequately ventilated.
Handling
The engine must be handled by experienced personnel,
using the prescribed tool or a rocker arm that keeps the
lifting lines parallel and with adequate equipment in terms
of capacity and size. The two eyebolts provided for lifting the
engine alone must always be used simultaneously.
Installation
o Knife switches or battery breakers may be used on the
power supply line of the engine electrical equipment
provided they are not used to shut the engine off.
o Do not modify the wiring harnesses; their length may
not be modified: use only available extensions.
o Do not use electronic device wiring harnesses not com-
pliant with the IVECO MOTORS directive, in terms of
length, type of conductor, location, clamping, connection
of the shielding and earth braids.
o To avoid any interference, the wiring harnesses of the
different on-board electronic devices must follow differ-
ent paths from those of the engine electronic systems.
o Do not connect any extraneous user device to the
engine electrical equipment.
o Do not place voltage across the boat's on-board electri-
cal system without first verifying that there are no short
circuits.
o Do not branch pipes off to draw fuel from the engine
supply lines.
insTAllATiOn direcTiVe
o Do not make any change to the engine's hydraulic circuits
and components.
o Do not execute arc welding operations before removing
the electronic units from their seating, placing them at an
adequate safety distance.a.
o Do not subject electronic units to temperatures exceed-
ing 80 °C.
o Do not paint electrical components and their connections.
o Comply with prescribed procedures and torque values
when tightening threaded elements.
Start-up
o Ready the engine following the procedure set
out in Chapter 22.
o When starting the engine the first time, have suitable
means available to cut off air intake in case of a runaway
condition.
o Start the engine after ensuring that it is complete with
every part specified by the manufacturer and required
by the installation, without attempting to start it with
caps and occlusions to the lubrication, cooling and fuel
feed lines.
o Check that the fluid lines are perfectly sealed, especially
lines for fuels and lubricants, which may cause fires and
consequent harm to persons and equipment.
o Make sure that the various pipelines are not in contact
with warm surfaces or moving parts.
o The installing yard is required to carry out tests to verify
the functional compatibility between the electrical-elec-
tronic equipment of the engine and the other electronic
equipment present on the boat.
Tests and tuning up
o Never disconnect the batteries when the engine is run-
ning.
o Remove the electrical connections from the batteries
before any operation on the electrical system.
o Ensure that the battery terminals comply with the exact
polarity, are properly tightened and protected against
accidental short circuits and corrosion phenomena..
o Do not connect or disconnect electrical connections
when electrical power supply is present.
o Do not cause sparks in the attempt to verify the pres-
ence of electrical voltage.
o Do not draw fuel through unfiltered lines.
o Do not clean the engine and its parts with corrosive or
abrasive detergent substances, to avoid compromising
the integrity of electrical connections.
o The engine fluids and air, water, and oil filters discarded
after use must be properly stored and delivered to
appropriate collection centers.
