1.1 FOREWORD

FOREWORD 1.1 FOREWORD This manual has been carried out by Komatsu Utility in order to supply their customers with all the necessary information on the machine and the safety regulations related to it, together 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 the machine, so that it can be consulted at any moment; it must be placed in the appropriate compartment behind the seat, where also the ownership documents and the logbook are usually kept (see “3.5.9 TECHNICAL DOCUMENTATION”). This manual must be given to the persons 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 upon request. Komatsu Utility machines are constantly improved in order to increase their efficiency and reliability; this manu- al sums up all the information regarding the most recent techniques applied at the moment in which the ma- chine is marketed. For any further and/or updated information, contact your Komatsu Utility Dealer.

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 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 are the data that must always be indicated to the Dealer when requiring assistance and ordering spare parts.

CAUTION The incorrect use of the machine and inappropriate maintenance operations may cause serious inju- ries and even death. Operators and maintenance personnel must carefully read this manual before using the machine or performing maintenance operations. Any serious accident that may occur during the use of the machine or during maintenance operations is due to failure to comply 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 described herein, the operator shall be responsible for his own safety and for the safety of any other person involved. 1

1.2 INFORMATION ON SAFETY

INFORMATION ON SAFETY 1.2 INFORMATION ON SAFETY Many accidents are caused by insufficient knowledge of and failure to comply with the safety regulations pre- scribed for the maintenance operations that must be performed on the machine. In order to avoid accidents, before starting work and before carrying out any maintenance operation, carefully read and be sure to understand all the information and warnings contained in this manual and given on the plates applied onto the machine, so that you can follow the instructions without making mistakes. To identify the messages regarding safety that are included in this manual and written on the machine plates, the following words have been used.

DANGER This word is used in the safety warnings in the manual and on the plates when the situation is dangerous and it may possibly result in serious injuries or even death. These messages describe the safety precautions to be taken in order to avoid any risk. Non-compliance with these instructions may also result in serious damage to the machine. CAUTION This word is used in the safety warnings in the manual and on the plates to sig- nal risks that may cause moderate damage or injuries. The message can be used even to indicate the risk of damage to the machine only.

IMPORTANT This word is used when precautions are indicated, which must be taken to avoid actions that may shorten the life of the machine. Komatsu Utility cannot reasonably predict every circumstance that might involve a potential hazard during the op- eration or maintenance of the machine; for this reason, the safety messages included in this manual and applied onto the machine may not include all possible safety precautions. If all the procedures and operations prescribed for this machine are kept to, you can be sure that the operator and the persons in the vicinity can work in total safety, with no risk of damaging the machine.

In case of doubt regard- ing the safety measures necessary for some procedures, contact Komatsu Utility or your local Dealer. DANGER Before starting any maintenance operation, position the machine on firm and level ground, engage the safety locks of the equipment and of the controls, stop the engine and apply the parking brake. DANGER To make the information clearer, some illustrations in this manual represent the machine without safety guards. Do not use the machine without guards and do not start the engine when the engine protection casing is open, if this is not expressly prescribed for some specific maintenance operations. 2
