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 and safe use of the engine
never, under any circumstances
wiring and to the units equipping the engine, or connect them
the
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 be handled 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 machine in
which it installed has satisfied all necessary safety requirements,
or until the machine 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.
