Introduction; Foreword - Komatsu 930E-4SE Operation & Maintenance Manual

OM1074 8/11

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 of its systems in order to keep it operating safely and efficiently. All
operators and maintenance personnel should read and understand the information in this manual before operating
the truck or performing maintenance and/or operational checks on the truck. All safety notices, warnings, and
cautions should be understood and followed when operating the truck or performing repairs on the truck.
A product identification plate is located on the frame in front of the right side front wheel. It 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 "M", when present, designates a Mechanical drive system.
The letter "E", when present, designates an Electrical wheel motor drive system.
The Product Identification Number (vehicle serial number) contains information which identifies the original
manufacturing bill of material for this unit. This complete number will be necessary for proper ordering of many
service parts and/or warranty consideration.
The Gross Vehicle Weight (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 maximum GVW.
GVW is total weight: empty vehicle weight + fuel & lubricants + payload.
To determine the allowable payload, fill all lubricants to the proper level and fill the fuel tank of an empty truck
(which includes all accessories, body liners, tailgates, etc.), and then weigh the truck. Record this value and
subtract it from the GVW. The result is the allowable payload.
NOTE: Accumulations of mud, frozen material, etc, become part of the GVW and reduces the allowable payload.
To maximize payload and to keep from exceeding the maximum GVW rating, these accumulations should be
removed as often as practical.
Exceeding the allowable payload will reduce the expected life of truck components.
