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):
z Only equipment approved by national legislation may be
used
z The unit must be fixed in position
z Portable or mobile units may only be used inside the vehi-
cles if they are connected to a fixed outside antenna
z The transmitter unit must be spatially separated from the
vehicle’s electronic system
z Make sure when installing the antenna that this is installed
correctly with good earth connection between antenna and

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 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.

Foreword 1.7 CE-Conforming equipment
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 customer 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 alongside.
The certification must be sent to the customer and the wheel
loader manufacturer. The CE conformity declaration for a specific wheel loader is only legally valid once this has taken place.
The dimensions X1, X2, Y1 and Y2 must be provided by the customer 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.
