Foreword:

• This publication provides the data, characteristics, instructions and procedures for carrying out repairs on the vehicle
  and its components. This publication is intended for qualified and specialized personnel. The personnel of the
  Komatsu sales and assistance network as well as all Komatsu authorized service points are specifically qualified
  and equipped to carry out the repair operations indicated in this publication. Before carrying out any intervention,
  make sure you have the publication for the vehicle model on which you are about to operate and also make sure that
  all the accident prevention devices, including but not limited to, glasses, helmet, gloves, shoes, etc. as well as the
  work, lifting and transport equipment, etc., are available and efficient. Ensure that the vehicle is in such a condition
  that the work can be carried out safely. The execution of the interventions in strict observance of the indications
  provided here, as well as the use of the specific equipment indicated, guarantees the correct repair intervention,
  observance of the execu-tion times and the safety of the operators. Any repair intervention carried out must serve
  to restore the conditions of functionality, efficiency and safety required by Komatsu. Any intervention on the
  vehicle to modify, alter or any other intervention not authorized by Komatsu will relieve Komatsu of all and any
