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 liability and, in particular, if the vehicle is covered by warranty, implies the immediate forfeiture of the warranty.
• Komatsu is not responsible for carrying out repairs. Komatsu is available to provide all the clarifications necessary for the execution of the interventions as well as to provide indica-tions in cases and situations not provided for in this publication.

The data and information contained in this publication might not be updated as a result of changes made by
Komatsu, at any time, for technical or commercial reasons or due to the need to adapt the vehicle to the legal
requirements of the different countries. In case of discrepancy between the indications provided in this publication
and what is actually found on the vehicle, please contact the Komatsu network before proceeding with any
intervention.
The complete or partial reproduction of the text or illustrations herein is forbidden.
The service manual is divided into the following sections:
• INTRODUCTION
• ENGINE
• INJECTION
• CHASSIS
• ELECTRICAL COMPONENTS
The “INTRODUCTION” chapter contains the Safety Regulations, the description of the symbols used in the document,
the engine identification dataplate and the scheduled maintenance plan.
Each section is divided into chapters; each chapter can be identified by a unique four-digit numerical code and is
related to a sub-assembly of the engine.
