NON-OEM PARTS IN CRITICAL SYSTEMS For safety reasons, Komatsu America Corp. strongly recommends against the use of non-OEM replacement parts in critical systems of all Komatsu equipment. Critical systems include but are not limited to steering, braking and operator safety sys- tems. Replacement parts manufactured and supplied by unauthorized sources may not be designed, manufactured or assembled to Komatsu's design specifications; accord- ingly, use of such parts may compromise the safe operation of Komatsu products and place the operator and others in danger should the part fail. Komatsu is also aware of repair companies that will rework or modify an OEM part for reuse in critical systems.

Komatsu does not generally authorize such repairs or modifications for the same reasons as noted above. Use of non-OEM parts places full responsibility for the safe performance of the Kom- atsu product on the supplier and user. Komatsu will not in any case accept responsi- bility for the failure or performance of non-OEM parts in its products, including any damages or personal injury resulting from such use.

FOREWORD

OM1042 03/13 Introduction - Section 10 Page 10-1 FOREWORD This manual is written for use by the operator and/or the service technician and is designed to help these persons to become fully knowledgeable of the truck and all its systems in order to keep it operating safely and efficiently. All operators and maintenance personnel must understand the content in this manual before operating, maintain- ing or performing operational checks on the truck. All safety notices, warnings and cautions must be understood before operating or repairing the truck. The first section is an introduction to the manual and contains a table of contents to locate specific areas of inter- est.

Other sections include Safety, Operation, Maintenance, Specifications, and Optional Equipment. This manual shows dimensioning of metric and (U.S. standard) units throughout. All references to right, left, front, or rear are made with respect to the operator's normal seated position, unless specifically stated otherwise. Standard torque requirements are shown in torque charts in the Introduction section and individual torques are pro- vided in the text in bold face type, such as 135 N·m (100 ft lbs) . All torque specifications have ±10% tolerance unless otherwise specified.

The illustrations used in this manual are typical of the component shown and may not be an exact reproduction of what is found on the truck. A product identification plate is located on the frame in front of the right side front wheel and designates the truck model number, product identification number (vehicle serial number), and maximum Gross Vehicle Weight (GVW) rating. The product identification number (vehicle serial number) contains information which will identify the original manu- facturing bill of material for this unit. This complete number will be necessary for proper ordering of many service parts and/or warranty consideration.

The GVW is what determines the load on the drive train, frame, tires, and other components. The vehicle design and application guidelines are sensitive to the total maximum GVW. GVW is the total truck weight. This is equal to the empty vehicle weight + the fuel & lubricants + the payload. To determine allowable payload: Service all lubricants to the proper level including the fuel tank. Weigh the empty truck This includes all accessories, body liners, tailgates, etc. Record this value and subtract from the GVW rating. The result is the allowable payload. NOTE: Accumulations of mud, frozen material, etc. become a part of the GVW and reduces allowable payload.

To maximize payload and to keep from exceeding the GVW rating, these accumulations must be removed as often as practical. Exceeding the allowable payload will reduce expected life of truck components.
