General remarks and safety information
GENERAL NOTES
.
Lombardini engines are built to provide safe and
longlasting performances, but in order to obtain these
results it is essential that the maintenance requirements
described in the manual are observed along with the
following safety recommendations.
. The engine has been built to the specifications of a machine
manufacturer, and it is his responsibility to ensure that all
necessary action is taken to meet the essential and legally
prescribed health and safety requirements. Any use of the
machine other than that described cannot be considered
as complying with its intended purpose as specified by
Lombardini , which therefore declines all responsibility for
accidents caused by such operations.
. The following instructions are intended for the user of the
machine in order to reduce or eliminate risks, especially
those concerning the operation and standard maintenance
of the engine.
. The user should read these instructions carefully and get to
know the operations described. By not doing so he may
place at risk his own health and safety and that of anyone
else in the vicinity of the machine.
. The engine may be used or mounted on a machine only
by personnel suitably trained in its operation and aware of
the dangers involved. This is particularly true for standard
and, above all, special maintenance work. For special
maintenance contact personnel trained specifically by
Lombardini . This work should be carried out in accordance
with existing literature.
.
Lombardini declines all responsibility for accidents or for
failure to comply with the requirements of law if changes
are made to the engine’s functional parameters or to the
fuel flow rate adjustments and speed of rotation, if seals
are removed, or if parts not described in the operating and
maintenance manual are removed and reassembled by
unauthorized personnel.
WARNING
.
In addition to all other machine specifications, ensure that
the engine is in a near horizontal position when starting.
lf starting manually, ensure that the necessary operations
can be performed without any risk of striking against walls
or dangerous objects. Rope starting (except for recoil rope
starting) is not permitted even in emergencies.
. Check that the machine is stable so that there is no risk of it
overturning.
.
Get to know the engine speed adjustment and machine stop
operations.
. Do not start the machine in closed or poorly ventilated
environments. The internal combustion process generates
carbon monoxide, an odourless and highly toxic gas, so
spending too long a time in an environment where the engine
discharges its exhaust products freely can lead to loss of
consciousness and even death.
.
The engine may not be used in environments containing
flammable materials, explosive atmospheres or easily
combustible powders, unless adequate and specific
precautions have been taken and are clearly stated and
certified for the machine.
.
To prevent the risk of fire, keep the machine at a distance of at
least one metre from buildings or other machines.
. Children and animals must be kept at a sufficient distance from
the machine to prevent any danger resulting from its operation.
.
Fuel is flammable, so the tank must be filled only when the
engine is turned off. Dry carefully any fuel that may have
spilled, remove the fuel container and any cloths soaked
in fuel or oil, check that any sound-absorbing panels made
of porous material are not soaked with fuel or oil, and make
sure that the ground on which the machine is located has not
absorbed fuel or oil.
.
Before starting, remove any tools that have been used for
carrying out maintenance work to the engine and/or the
machine and check that any guards removed have been
replaced. In cold climates it is possible to mix kerosene with
the diesel fuel to make the engine easier to start. The liquids
must be mixed in the tank by pouring in first the kerosene and
then the diesel fuel. Consult Lombardini technical office for
mixture proportions. Petrol may not be used because of the
risk of it forming flammable vapours.
.
During operation the surface of the engine reaches
temperatures that may be dangerous. Avoid in particular all
contact with the exhaust system.
. The liquid cooling circuit is under pressure. Do not carry out
any checks before the engine has cooled down, and even
then open the radiator cap or the expansion tank cautiously.
Wear protective clothing and glasses. lf there is an electric
fan, do not approach the engine while it is still hot as the fan
may come on even when the engine is not running. Clean the
cooling system with the engine turned off.
. While cleaning the oil bath air filter, check that the oil is
disposed of in such a way as not to harm the environment.
Any filtering sponges in the oil bath air filter should not be
soaked with oil. The cyclone pre-filter cup must not be filled
with oil.
. Since the oil must be emptied out while the engine is still hot
(approx. 80°C), particular care should be taken in order to
avoid burns. In any case make sure that oil does not come into
contact with your skin because of the health hazards involved.
. Fuel vapours are highly toxic, so fill up only in the open air or in
well ventilated environments.
This manual contains safety precautions which are explained
below.
