GENERAL INFORMATION
The illustrations contained in this document were up to date at the time of publication.
The illustrations are provided purely as a rough guide and may show the machine with its
protective devices removed for easier understanding.
1.3.3 Scope of this manual
This document has been prepared pursuant to standards and legislation in force at the time
of its publication.
The purpose of this manual is to provide all the information necessary to be able to use and handle
the machine in a correct and safe manner according to the use envisaged by the manufacturer.
The manual contains a description of the machine, its technical and functional characteristics,
descriptions of the safety and control devices, all information necessary for the operator to use it
correctly and safely, the methods for performing checks and maintenance, as well as the information
for compiling the check register.
This manual refers exclusively to the machine type and model indicated on the cover.
This manual is not intended to train inexpert operators or to teach people how to use the
machine. All descriptions assume that the machine will only be used by operators trained

adequate operator training.
The operator is directly responsible for the machine and its use.
This manual does not contain instructions for maintenance operations, which must be
performed only by specialised personnel or by CTE SpA authorised service centres.
CAUTION
Before using the machine, carefully read the manual and be sure you understand
all the safety standards and operating instructions.
Contact the manufacturer or the nearest service centre if in doubt.
Correct use and maintenance contribute to the proper operation and longer lifetime of the machine.

1.3.7 Conservation
This manual is an integral part of the machine and should be stored with care in the cab
dashboard so it can be readily consulted at any moment.
The manual must always accompany the machine along with the CE declaration of conformity,
the check register and any other documents relating to the machine, including in the event
that it is sold, up until such time as it is removed from service or disposed of.
Make a note of the fabrication number on the cover in order to easily identify the manual.
If the manual is lost or has deteriorated, request a new copy from the manufacturer, quoting
the code on the cover or the machine’s factory number.
