Introduction 1.1. Foreword
Please note:
If the owner modifie s saf ety -re late d parts of the m ac hi ne, t he c ertificate of conformity of the manufacturer will lapse and the person
who has performed the modification has to issue a new cer tificate. Should you have any questions concerning this poin t,
please do not hesitate to ask Komatsu.
Our continuous effort to improve the machine's design may lead
to changes of machine details. Howev er, the introduction of these
improvements does not oblige us to perfor m them on machin es
which have already been delivered and are already in use.
If these improvements result in minor changes, these minor
changes will not be described in the operating instructio ns.
Should you require new available information about your machine
or have any questions conce rning the information given in the
operating instruct ions, please do not he sitate to contact either
Komatsu or your responsible Komatsu dealer.
These operating instructions may refer to attachments and special equipment not avail able from your loca l Komatsu dealer.
Should you requ ire attachments or special equip ment, ask your
responsible Komatsu dealer.
EU Directives
This machine is l ab ell ed wit h th e CE m ar k in dic ati ng tha t i t me ets
all basic requir ements con cernin g safety an d prote ction of he alth
of the EU Machinery Directive 89/392/EEC, its supple ments 91/
368 EEC and 93/44 EEC for Europe, and the regulation 95/27/
EEC. In addition, the harmonised European standards EN 292-2
and EN 474/1 of 1994, and EN 474-3 of 1996 were applied for
manufacture of th e machi ne. Th is fact i s docu mented i n the E U
Declaration of Conformity (CE) which is supplied together with the
machine.
This means that in those cases in which the machine is modified
in such a way that safe ty of the m achine i s affected, the p erson
responsible for safety of the machine is the one who has
arranged for the machine to be modified. If you use the machine
for any other purpose t han that de fined as c orrect use , you are
the person who has to ens ur e t hat s afe ty is mai ntaine d. Mo dif ic ations of the mach ine or u se of the mac hine for a ny oth er purpo se
than that specified as correct use may require a new CE mark
and thus new issuing of an EU Declaration of Conformity.
If a machine is used in oth er countries than Germany, it may be
possible that special national safety devices and specifications
are missing which may be requ ired for the ap plicati on in the rel evant country. For example, for Komatsu machines, the manufacturer has to design the cab roof in such a way that a warning
beacon can be attached to the roof. However, when driving the
machine on roads, this warning beacon must be covered.

persons. For this reason, strictly adhere to the following safety
notes.
If you later install electrical and electronical devices and/or components in the machine and connect them to the vehicle electrical
system, you are responsible for any malfunctions of the vehicle
electronics or other components resulting from this installation.
Above all, check that all electrical and electronical components
which you install lat er comply wi th the valid version of t he EMC
directive 89/336/EEC and that they are labelled with the CE mark.
The following requirements must additionally be met for a later
installation of mobile com munication sys tems (e.g. radio, tele phone):
● Only install devices which have a licence referring to valid
national regulations.
● The device must be stationary.
● Only use portable or mobile devices in the cab, if they are
connected to a stationary external aerial.
● Install the sender in s uc h a wa y that it is phys ical ly s epara ted
from the vehicle electronics.
● When installing the aerial, make sure that it is installed cor-
rectly with a good chassis earth connection between the

1.3. Introduction
1.3.1. Intended use
This loader is a machine with independent transmission, moving
on wheels. Driving in for ward di rection , the lo ader can lo ad or dig
material using its attachments intended for loading operations (i.e.
bucket).
The standard operation cycle of a loader includes filling up and
loading of the bucket, transporting the material and emptying the
bucket.
In combination with the forklift truck attachment the picking up,
transporting and putting down of stacked material is also
considered to be part of the machine’s intended use.
If you use the machine for any other purpose than specified
above, we will not accept any responsibility for safety. All
considerations concerning safety will then be up to the owner or
the operating and maintenance personnel. In any case, neither
you nor any other person are/is authorised to perform work and
functions explicitly prohibited in these operating instructions.

1.3. Introduction Introduction
1.3.2. Breaking-in the machine
Before the shipment, each machine was carefully checked and
adjusted. A machine that is to be newly commissioned has to be
treated with utmost care during its first 100 operating hours.
If the machine is used for work involving loads exceeding the
specified maximum load for the running-in period, its performance
may be impaired prematurely and its service life may be shortened. A new machine must be run i n and maintained very c arefully and thoroughly.
The following points are particularly important:
● Idle the engine for 5 minutes after starting it up.
● Avoid operation with heavy loads or at high speeds.
● Avoid sudden starts, sudden acceleration, sudden steering
und sudden stops except in cases of emergency.
The precautions given i n this manu al for opera ting, m ainten ance,
and safety procedures are only those that apply when this product
is used for the specified purpose. If the machine is used for a purpose that is not listed in this manual Komatsu cannot bear any
responsibility for safety. All consideration of safety in such opera tions is the responsibility of the user.
Operations that are prohibited in this manual must never be carried out under any circumstances.

Introduction 1.6. CE-conforming equipment
1.6.3. Manufacturer-supplied CE-conforming equipment
The responsibility for observing valid regulations in the case of
wheel loaders with "int erchangeabl e equipment" (e.g. bucket or
fork-lift) which was not supplied from works lies with the customer
which was subsequently fitted to the machine.
The guidelines for C E Con formity and road- traffic reg istrati on a re
deemed to have been fulfilled when the manufacturer of the
equipment confirms fulfilment of the document.
The certification must be sent to the customer and the wheel
loader manufactur er. The CE co nformi ty d ec larat ion fo r a s pecific
wheel loader is only legally valid once this has taken place.
The dimensio ns X1, X2, Y1 and Y2 must be provid ed by the
manufacturer of the equipment for approval for use on public
roads.
The dimension Sh (sm allest tyre radi us) must be add ed to the
dimension D2.
The figure G (in k g) represents the m aximum load (e quipment
and operating load) which may act upon this point.
