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 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 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 specically 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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 Kohler 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.
. 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 specic 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 lter and the oil
containedintheoillteraredisposedofinsuchawayasnot
toharmtheenvironment.
. Close the fuel tank ller cap carefully after each fílling
operation.  Do not ll the tank right up to the top, but leave
sufcientspacetoallowforanyexpansionofthefuel.
. Donotsmokeorusenakedameswhilelling.
