Unauthorised modifications on the upperframe can
have an influence on the ROPS protection system
which is intended to secure the driver in case of an
accident.
Modifications may be considered to be officially
approved, if at least one of the following conditions
has been met:
1 The attachment, the accessory, the unit, or the
part has been manufactured or distributed by
Volvo Construction Equipment and has been
installed according to the factory-approved
method described in a publication available from
Volvo Construction Equipment; or
2 The modification has been approved in writing
by the Engineering Department for the relevant
product line at Volvo Construction Equipment.
Travel system
The travel motion is accomplished by the main
chassis via two rubber tracks (steel tracks optionally

Anti-theft device
An anti-theft device makes it more difficult to steal
the machine. Volvo offers an anti-theft device as
optional equipment. If your machine is not yet
equipped with it, check the possibility of having
such a device activated by your dealer.
CareTrack
The machine may be equipped with CareTrack, a
telematics system developed by Volvo
Construction Equipment. The system stores
machine data, e.g., machine position, operating
hours, fuel consumption, fuel level, that can be sent
by wireless transmission to a computer. CareTrack
is available in different versions, depending on the
required information level.
CareTrack makes it easier to plan for service and
reduces costly downtime. Productivity is improved
by knowing if machines are being operated
correctly and how much fuel is being consumed.
CareTrack also allows the customer to restrict the
operating area of the machine, by using virtual
fences. This helps to eliminate unauthorized
machine use and theft. For further information,
contact a Volvo Construction Equipment dealer.
The CareTrack system transmits data, in the same
way a mobile phone does, with a maximum output
rate of 10 W. The transmitter is always on and the
operator cannot switch it off.
Local precautions and restrictions applicable to
mobile phones, for example safety distance, also
apply to the CareTrack system.

CE-marking, EMC-directive
CE marking
(Declaration of Conformity)
This machine is CE-marked. This means that, when
delivered, it meets the applicable "Essential Health
and Safety Requirements", stated in EU's so-called
Machine Safety Directive, 2006/42/EC.
Any person making changes that affect machine
safety is also responsible for the same.
An EU Declaration of Conformity as well as a sound
certificate regarding sound power in dB(A) are
supplied as proof that the requirements are fulfilled.
The sound certificate includes both measured
external values and guaranteed sound power level.
These declarations are issued by Volvo for every
individual machine. This EU-declaration also
includes attachments manufactured by Volvo. The
documentation is a valuable document and shall be
saved in a safe location for at least ten years. The
documentation shall always accompany the
machine when it is sold.
If the machine is used for other applications or with
other attachments than described in this manual,
safety must always be ensured in each individual
case. A change may in certain cases require a new
CE-marking and issuing of a new EU Declaration of
Conformity. The person responsible for this is the
same person who makes the change.
EU EMC Directive
The machine's electronic equipment may in some
cases interfere with other electronic equipment, or
be interfered with by external electromagnetic
interference, which may result in safety risks.
EU's EMC directive about "Electromagnetic
compatibility", 2004/108/EC, provides a general
description of what requirements can be made of
the machine from a safety perspective, where
permitted limit values have been determined and
stated in international standards.
A machine or device must meet the requirements
to be CE-marked. Our machines have been
specially tested for electromagnetic interference.
The machine's CE-marking and the Declaration of
Conformity also cover the EMC directive.

Communication equipment,
installation
NOTICE
All installation of optional electronic communication
equipment must be performed by trained
professionals and in accordance with the Volvo
Construction Equipment instructions.
Protection against electromagnetic interference
This machine has been tested according to EU's
directive 2004/108/EC that regulates
electromagnetic interference. Therefore, it is very
important that all non-approved electronic
accessories, such as communication equipment,
are tested before they are installed and used, since
they may interfere with the machine's electronic
system.
Guidelines for installing aerial
The guide lines listed below must be followed
during installation:
The position of the aerial must be selected to
provide satisfactory adaptation to the surrounding
area.
The aerial downlead must be of the coaxial cable
type. Make sure that the cable is undamaged, that
the screen is not split at the ends and that it
thoroughly surrounds the contact sheaths and
has good galvanic contact with the same.
The surface between the mounting bracket for the
aerial and the point of attachment must be free
from dirt and oxide. Apply corrosion protection to
the surfaces after installation so that good
galvanic contact is maintained.
Take care to separate cables that may cause
interference from those which may suffer
interference. Cables that may cause interference
are voltage feed cables and the aerial cable to the
communication equipment. Cables that may
suffer from interference are connecting cables for
the electronics of the machine. Install cables as
close as possible to plate surfaces which are
connected to ground (earthed), as these have a
screening effect.
