1.1 FOREWORD

FOREWORD 1.1 FOREWORD This manual has been developed by Komatsu Utility in order to supply their customers with all the necessary in- formation on the machine and the safety regulations related to it, as well as with the use and maintenance in- structions that enable the operator to exploit the capacity of the machine with optimal results and to keep the machine efficient over time. The operation manual, together with the spare parts catalogue, is an integral part of the machine and must ac- company it, even when it is resold, until its final disposal.

The manual must be handled with the greatest care and always kept on board, so that it can be consulted at any moment; it must be placed in the appropriate compartment behind the seat, where also the owner’s and registra- tion documents are usually kept. This manual must be given to the personnel who have to use the machine and carry out the routine maintenance operations; they must read the contents carefully more than once, in such a way as to clearly understand what are the correct operating conditions and the dangerous conditions that must be avoided. In case of loss or damage, request a new copy to Komatsu Utility or your Komatsu Utility Dealer.

The illustrations contained in this manual may represent machine configurations available on request. The machines are constantly upgraded in order to increase their efficiency and reliability; this manual sums up all the information regarding the state of the art at the moment when the machine is launched on the market. Consult your Komatsu Utility Dealer for any updated information. Punctual periodic annotations regarding the maintenance operations that have been carried out are important to have a clear prospect of the situation and to know exactly what has been done and what has to be done after the next maintenance interval.

Therefore, it is advisable to consult either the hour meter and the maintenance plan frequently. Over the years Komatsu Utility Dealers have gathered considerable experience in customer service. If more information is needed, do not hesitate to contact your Komatsu Utility Dealer: he always knows how to get the best performance from the machine, he can suggest the use of the equipment that is most suitable for specific needs and can provide the technical assistance necessary for any change that may be required to con- form the machine to the safety standards and traffic rules.

Furthermore, Komatsu Utility Dealers also ensure their assistance for the supply of Komatsu Utility genuine spare parts, which alone guarantee safety and interchangeability. The table included in this manual must be filled in with the machine data, which must always be indicated to the Dealer when requiring assistance and ordering spare parts. Incorrect use and maintenance of the machine may be hazardous and cause serious injury and even death. Operators and maintenance personnel must carefully read this manual before using the machine or per- forming maintenance operations.

Some actions involved in the operation and maintenance of the machine may cause serious injury or even death, if they are not performed in compliance with the instructions given herein. The procedures and precautions described in this manual are valid for application to the machine only when it is used correctly. If the machine is used for any purpose or in any way other than those de- scribed herein, the operator shall be responsible for his own safety and for the safety of any other per- son involved. 1 ATTENTION
