OM1059 07/08 Introduction - Section 1 Page 10-1 INTRODUCTION FOREWORD This manual is written for use by the operator and/or the service technician. It 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 read and understand the materials in this manual before operating the truck or performing maintenance and/or operational checks on the truck. All safety notices, warnings, and cautions must be understood and followed when operating or repairing 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 GVW (Gross Vehicle Weight) rating. The Komatsu truck model designation consists of three numbers and one letter (i.e. 930E). The three numbers represent the basic truck model. The letter E, when present, designates an electrical wheel motor drive system. 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 Gross Vehicle Weight (GVW). GVW is total weight: the empty vehicle weight + the fuel and lubricants + the payload. To determine allowable payload, fill all lubricants and fuel tank to the proper level. Weigh the truck and record this value. Subtract it from the GVW to determine the allowable payload. NOTE: Accumulations of mud, frozen material, etc., become 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 the expected life of truck components.
