The operating manual is to be considered part of the machine and
should be stored in the lid of the hinged panel in the left side of
the operator's cab.
Any safety-relevant modification to the machine by the owner
voids the manufacturer's declaration of conformity.
Our continuous efforts to improve the machine's design may
result in minor changes to the machine.
The introduction of these improvements however does not con-
stitute an obligation on our part to implement the same changes
in machines already delivered and operating. Minor changes due
to improvements are not covered by this manual.

EU Directives
Machines delivered by Komatsu are compliant with the Machine
Directive 2006/42/EEC and its amendments. If the machine is
used in another country, it is possible that certain safety devices
and specifications may not be compliant with the requirements
applicable in the country of use. For example, warning beacons
may be used in some countries while being prohibited in others.
If there is any question about whether your product complies with
the applicable standards and regulations of your country, consult
your Komatsu distributor before operating the machine.
Notes on subsequent installation of electrical and electronic
equipment and components
Electrical and electronic equipment and/or components installed
after delivery emit electromagnetic radiation which may possibly
influence the function of the electronic components and assem-
blies of the machine. This may affect the safety of the machine or
endanger persons. For this reason, please ensure that the follow-
ing safety instructions are observed.
If you are installing electrical or electronic equipment and/or com-
ponents in the machine and connect them to the vehicle's electri-
cal system, you are obliged to have the installation verified for not
interfering with vehicle's electronic system or other components.
In particular, please ensure that any subsequently installed elec-
trical and electronic components comply with the EMC Directive
2004/108/EC in its currently valid version and that they have CE
marks.
The following requirements also have to be met for subsequent
installation of mobile communication systems (e.g. radio, tele-
phone):
Only equipment approved by national legislation (e.g. BZT
approval for Germany) may be installed.
The unit must be fixed in position.
Portable or mobile units may only be used inside the vehicles
if they are connected to a fixed outside antenna.
The transmitter unit must be spatially separated from the
vehicle’s electronic system.
Ensure that the antenna is installed properly with a good
earthing connection between the antenna and the vehicle
earth.
Also observe installation instructions by Komatsu or the manufac-
turer for wiring, installation and maximum permitted power con-
sumption.

corresponds to the signal word. The pictures used are intended
to help the operating and maintenance personnel understand the
level and type of hazard at all times. Safety pictograms show the
type of hazardous condition at the top or on the left side, and the
method of avoiding the hazardous condition at the bottom or on
the right side. In addition, the type of hazardous condition is dis-
played inside a triangle, and the method of avoiding the hazard-
ous condition is shown inside a circle.
Komatsu cannot predict every circumstance that might involve a
potential hazard in operation and maintenance. Therefore, the
safety messages in this manual and on the machine may not
include all possible safety precautions.
If any procedures or actions not specifically recommended or
allowed in this manual are used, it is your responsibility to take
the necessary steps to ensure safety.

1.3 Introduction
This loader is an independently powered machine moving on
wheels. Using the equipment (e.g., a bucket or fork) installed to
its front, the loader can be used to load or dig material while mov-
ing forwards.
This Komatsu machine is designed to be used mainly for the fol-
lowing work:
Digging
Smoothing
Pushing
Loading
1.3.1 Intended use
If you use the machine for any other purpose than those specified
above, we will not accept any responsibility for its safety. Any con-
siderations regarding 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 func-
tions explicitly prohibited in these operating instructions.

1.3.2. Breaking in the machine
Every machine has been thoroughly tested and set up before
shipping. However, a new machine needs to be handled carefully
during the first 100 hours of service.
If the machine is worked excessively hard during the breaking-in
period, this will cause premature deterioration of performance
and shorten the machine's service life. A new machine needs to
be broken in and serviced carefully.
Particularly observe the following points:
Let the engine run at idle for 5 minutes after starting.
Avoid operation with heavy loads or at high engine speeds.
Avoid sudden starts and stops, hard acceleration and sudden
steering movements, except in emergencies.
The precautions for operation and maintenance in this manual as
well as the safety information apply only as long as the product is
used according to the specified intended use. If the machine is
used for any purpose not listed in this manual, Komatsu cannot
accept any responsibility for safety. In such cases, any safety
considerations are the sole responsibility of the operator.
Never perform any type of work or use the machine in any way
that is expressly prohibited in this manual.
