1.1.1 EU Directives
Machines supplied by us fulfil the Directive for Machinery 89/
392/EEC and all supplements. If the machine is being used in
another country, it is possible that certain safety regulations and
specifications may not be fulfilled for use in that country. For
example, priority vehicle warning lamps may be used in some
countries, but are forbidden in others.
Please contact our dealer before using the machine if you have
any questions regarding the fulfilment of standards and regula-
tions in a specific country.
Notes on subsequent installation of electrical and elec-
tronic equipment and components
Electrical and electronic equipment and/or components which
have been installed subsequently, emit electromagnetic radia-
tion which can influence the function of the electronic compo-
nents and sections of the machine. This can have an influence
on the safety of the machine and endanger persons. For this
reason, please ensure that the following safety instructions are
observed.
If you are installing electrical or electronic equipment and/or
components in the machine and connect them to the vehicle
electrical system, you must check at own responsibility that the
installations do not cause any disturbance to the vehicle’s elec-
tronic system or other components. Above all, you must ensure
that any subsequently installed electrical and electronic compo-
nents comply with the EMV Directive 89/336/EEC in its current
edition and bear the CE mark.
The following requirements also have to be met for subsequent
installation of mobile communication systems (e.g. radio, tele-
phone):
zOnly equipment approved by national legislation may be
used
zThe unit must be fixed in position
zPortable or mobile units may only be used inside the vehi-
cles if they are connected to a fixed outside antenna
zThe transmitter unit must be spatially separated from the
vehicle’s electronic system
zMake sure when installing the antenna that this is installed
correctly with good earth connection between antenna and
vehicle mass
Also observe KOMATSU and manufacturer’s installation instruc-
tions for wiring, installation and maximum permitted power con-
sumption.

Foreword 1.2 Safety information
WA150PZ-5 – VEAM420100 1-5
Other signal words
In addition to the above, the following signal words are used to
indicate precautions that should be followed to protect the
machine or to give information that is useful to know.
NOTE
This word is used for precautions that must be taken to
avoid actions which could shorten the life of the machine.

1.2.2 Safety labels
Safety labels are affixed to the machine to inform the operator or
maintenance worker on the spot when carrying out operation or
maintenance of the machine that may involve hazard.
For details of safety labels, see "Safety labels (2-2)".
Safety labels using pictogram
Safety pictograms use a picture to express a level of hazardous
condition equivalent to the signal word. These safety pictograms
use pictures in order to let the operator or maintenance worker
understand the level and type of hazardous condition at all
times. Safety pictograms show the type of hazardous condition
at the top or left side, and the method of avoiding the hazardous
condition at the bottom or right side. In addition, the type of haz-
ardous condition is displayed inside a triangle and the method of
avoiding the hazardous 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.
In no event should you engage in prohibited uses or actions
described in this manual.
The explanations, values, and illustrations in this manual were
prepared based on the latest information available at that time.
Continuing improvements in the design of this machine can
lead to changes in detail which may not be reflected in this man-
ual. Consult KOMATSU or your KOMATSU distributor for the
latest available information of your machine or for questions
regarding information in this manual.

Foreword 1.7 CE-Conforming equipment
WA150PZ-5 – VEAM420100 1-19
1.7.2 Manufacturer-supplied CE-Conforming equipment, according to
document 419-93-H1250
The responsibility for observing valid regulations in the case of
wheel loaders with "interchangeable equipment" (e.g. bucket or
fork-lift) which was not supplied from works lies with the cus-
tomer which was subsequently fitted to the machine.
The directives for CE conformity and road-traffic registration are
deemed to have been fulfilled when the manufacturer of the
equipment confirms fulfilment of the form 419-93-H1250 along-
side.
The certification must be sent to the customer and the wheel
loader manufacturer. The CE conformity declaration for a spe-
cific wheel loader is only legally valid once this has taken place.
The dimensions X1, X2, Y1 and Y2 must be provided by the cus-
tomer for approval for use on public roads.
The dimension Sh (smallest tyre radius) must be added to the
dimension D2.
The figure G (in kg) represents the maximum load (equipment
and operating load) which may act upon this point.
