GENERAL REMARKS AND SAFETY INFORMATION

SAFETY REGULATIONS

GENERAL NOTES

. Kohler 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 Kohler, 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

Kohler. This work should be carried out in accordance with

existing literature.

. Kohler 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.

- 8 -

. 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 Kohler 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.

. During operations which involve access to moving parts of

the engine and/or removal of the rotary guards, disconnect

and insulate the positive cable of the battery so as to prevent

accidental short circuits and activation of the starter motor.

. Check the belt tension only when the engine is turned off.

IMPORTANT

. To start the engine follow the specific instructions provided

in the engine and/or machine operating manual. Do not

use auxiliary starting devices not originally installed on the

machine (e.g. Startpilot systems which utilise ether etc.)

. Before carrying out any work on the engine, turn it off and

allow it to cool down. Do not perform any operation while the

engine is running.

. Check that the discharged oil, the oil filter and the oil

contained in the oil filter are disposed of in such a way as not

to harm the environment.

. Close the fuel tank filler cap carefully after each fílling

operation. Do not fill the tank right up to the top, but leave

sufficient space to allow for any expansion of the fuel.

. Do not smoke or use naked flames while filling.
