EU DIRECTIVES 0.
Machines supplied by us fulfil the Directive for Machinery 89/392/EEC and its 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 regulations in a specific country.
Notes on subsequent installation of electrical and electronic equipment and components
Electrical and electronic equipment and/or components which have been installed subsequently, emit electromag-
netic radiation which can influence the function of the electronic components 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 electronic system or other components. Above all, you must ensure that any subsequently installed
electrical and electronic components 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, telephone):
!Only equipment approved by national legislation (e.g. BZT approval for Germany) may be used
!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
!Make 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 instructions for wiring, installation and maximum permitted
power consumption

SAFETY INFORMATION FOREWORD

SAFETY INFORMATION 0.
To enable you to use this machine safely, safety precautions and labels are given in this manual and affixed to the
machine to give explanations of situations involving potential hazards and of the methods of avoiding such situa-
tions.
Signal words
The following signal words are used to inform you that there is a potential hazardous situation that may lead to per-
sonal injury or damage.
In this manual and on machine labels, the following signal words are used to express the potential level of hazard.
Indicates an imminently hazardous situation which, if not avoided, will result in death or seri-
ous injury. This signal word is to be limited to most extreme situations.
Indicates a potentially hazardous situation which, if not avoided, could result in death or
serious injury.
Indicates a potentially hazardous situation which, if not avoided, may result in minor or mod-
erate injury. It may also be used to alert against unsafe practices.
Example of safety message using signal word
WARNING
When standing up from the operator‘s seat, always place the safety lock lever in the LOCK position.
If you accidentally touch the levers when they are not locked, this may cause a serious injury or damage.
Other signal words
In addition to the above, the following signal words are used to indicate precautions that should be followed to pro-
tect the machine or to give information that is are useful to know.

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.
This machine uses “Safety labels using pictograms“ to indicate safety procedures.
For details of safety labels, see "SAFETY LABELS ( 2-3 )".
Safety labels using pictogram
Safety pictograms use a picture to express a level of hazard-
ous condition equivalent to the signal word. These safety picto-
grams 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 condi-
tion at the top or left side, and the method of avoiding the haz-
ardous condition at the bottom or right side. In addition, the
type of hazardous 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
manual. Consult Komatsu or your Komatsu distributor for the
latest available information of your machine or for questions
regarding information in this manual.
The numbers in circles in the illustrations correspond to the
numbers in ( ) in the text. (For example: 1->1)
