CAUTIONS
Use and servicing
-
When starting the engine the first time, have available
appropriate means to shut off engine air intake in case
of runaway speed rate.
-
Never disconnect the batteries electrically when the
engine is running.
-
Remove the batteries’ electrical connections before any
operation on the electrical system.
-
Ensure that battery terminals comply with the correct
polarity, that they are properly tightened and protected
against any short circuits and corrosion phenomena.
-
Do not connect or disconnect electrical connections
on supplied circuits.
-
Do not cause any sparks in the attempt to verify the
presence of electrical voltage.
-
Do not draw fuel from tanks made of copper alloys
and/or with pipes lacking filtering systems.
-
Do not wash the engine and its components with cor-
rosive or abrasive detergents, to avoid jeopardizing the
operating condition of the electrical connections.
Prolonged engine inactivity
The end of this section contains a list of the steps for
preparing the engine before long inactivity periods, and for
restoring it to its operating condition.
While an electronically controlled injection system provides
for better engine performance, it also makes it mandatory
for installing and servicing personnel to comply with some
fundamental rules that will surely become the norm as elec-
tronic engine control equipment becomes ever more wide-
spread.
Boat fitters and servicing personnel are invited to familiar-
ize themselves with the notes that follow and to contact
IVECO Aifo personnel whenever compliance should prove
impossible.
Failure to comply with the rules set out below
shall void the warranty and exonerate IVECO Aifo
from all liabilities.
Handling
The engine shall be handled by experienced personnel,
using the prescribed tool or an equalizer that will keep the
lifting lines parallel and with suitable equipment in terms of
load bearing capacity and size.
The two padeyes provided for lifting the engine alone shall
always be used simultaneously.
Installation
-
Use of switches or battery disconnects on the EMB
power supply line is not allowed.
-
Do not modify wiring; wire length cannot be changed.
-
Use only electronic device wiring compliant with the
IVECO standard, in terms of length, conductor type,
location, clamping, shielding and grounding braids con-
nection.
-
To avoid any interference, the wiring for devices other
than engine electronic systems must follow different
paths.
-
Do not connect any extraneous device to the engine
electrical equipment.
-
Do not provide electrical voltage to the boat’s system
before first verifying that there are no short circuits.
-
Do not insert pipes for drawing fuel from the engine
fuel supply pipelines.
-
Do not make any modification to the engine’s
hydraulic circuits and components.
-
Do not perform any electric arc welding operations
without first removing the electronic units from the
seat, placing them at a suitable distance for safety.
-
Do not subject electronic units to temperatures
exceeding 80 °C.
-
Do not paint electrical components and connections.
-
Do not alter the data contained in the engine control
unit.
-
Tighten threaded elements according to the prescri-
bed procedures and torque values.
Engine’s first start
Follow the procedure set out in the paragraph entitled
"Engine’s first start / Restoring normal operating conditions"
at the end of this section.
