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 specications 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 specied 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 specically 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 ow 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 specications, 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

ammable materials, explosive atmospheres or easily

combustible powders, unless adequate and specic

precautions have been taken and are clearly stated and

certied for the machine.

. To prevent the risk of re, keep the machine at a distance of at

least one metre from buildings or other machines.

. Children and animals must be kept at a sufcient distance from

the machine to prevent any danger resulting from its operation.

. Fuel is ammable, so the tank must be lled 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 rst the kerosene and

then the diesel fuel. Consult Lombardini technical ofce for

mixture proportions. Petrol may not be used because of the

risk of it forming ammable 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 lter, check that the oil is

disposed of in such a way as not to harm the environment.

Any ltering sponges in the oil bath air lter should not be

soaked with oil. The cyclone pre-lter cup must not be lled

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 ll up only in the open air or in

well ventilated environments.

This manual contains safety precautions which are explained

below.
