Contact your Komatsu Dealer for updated information. q 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 both the hour meter and the maintenance plan frequently. q Komatsu Dealers have gathered a considerable amount of experience over years of work in close contact with the users. If more information is needed, do not hesitate to contact your Komatsu Dealer: he always knows how to get the best performance from the machine, he can recommend the equipment that is most suitable for specific needs and can provide the technical assistance necessary for any change that may be required to conform the machine to the safety standards and traffic rules.

Komatsu Dealers also provide assistance for the supply of original Komatsu spare parts, which alone guarantee safety and interchangeability. q 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. q The incorrect use of the machine and inappropriate maintenance operations may cause serious injury and even death. q Operators and maintenance personnel must carefully read this manual before using the machine or performing maintenance operations.

q 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. q 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 CAUTION
