q 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 inside the seat support, where the registration documents and the logbook are usually kept. q This manual must be given to the staff 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 or your Komatsu Dealer.

q The illustrations contained in this manual may represent machine configurations available on request. Komatsu machines are constantly improved in order to increase their efficiency and reliability; this manual sums up all the information regarding the most recent technology applied at the moment in which the machine is launched. For any further and/or updated information, contact your Komatsu Dealer. q Punctual periodic annotations regarding the maintenance operations that have been carried out are important, since they provide a clear report on the situation and say 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 Over the years Komatsu Dealers have gathered considerable experience in customer service. 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.

Furthermore, Komatsu Dealers also offer assistance for the supply of Komatsu genuine spare parts, which guarantee safety and interchangeability. q The table included in this manual must be filled in with the machine data, which are also the data that must be communicated 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 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. q The application of the procedures and precautions described in this manual will ensure safety only provided that the machine 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
