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.
SAFETY REGULATIONS
. 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.
